Today’s consumers are swimming in a sea of information. Products are marketed with big, bold words such as “sustainable”, “ethical” and “organic”. They sound good, they catch our attention, and they make us feel better about what we buy.

The reality is, in today’s market, figuring out which claims are true is no easy task.

One big reason is greenwashing, when brands use these buzzwords to sell products without living up to what the words actually mean. In fashion especially, these terms are thrown around so often that their meaning has been watered down. Instead of being about genuine change, they are often just a sales tool.

So, how can you know what to look out for?

Who should take responsibility for green claims?

Greenwashing takes many forms. Sometimes brands know they are misleading; this is direct greenwashing. Other times, it’s indirect, when brands simply do not know the full story of their own supply chains. A T-shirt, for example, might start as raw cotton in one country, get processed into fabric in another, sewn into a garment, and then shipped overseas for sale.

At each stage, there are different suppliers, factories and workers. The brand has limited visibility over what happens in these tiers. When a brand claims it produces ethically, but does not, that is greenwashing. If it involves exploitation or forced labour, it then becomes modern slavery, turning greenwashing into something more dangerous.

This raises a big question: who is responsible? The obvious answer is the brands. They design, order, and sell the products, and they profit from them. Consumers are paying for these goods, so they should have access to credible information, not just vague claims or nice-sounding labels.

The fashion industry is constantly in the spotlight for problems in its supply chains. Stories about poor working conditions, environmental damage, and lack of transparency pop up all the time. But just like a viral trend on social media, the attention often fades quickly, and people move on to the next story.

Certifications aren’t perfect

There are many certifications in the fashion industry trying to help, but they are not foolproof. A label might promise ethical sourcing, but that does not guarantee transparency or prove that every step was ethical.

A large portion of China’s cotton comes from the Xinjiang region, which has long been linked to forced labour; concerns were highlighted in a United Nations report in 2022. Another example is deforestation in Brazil, where cotton from affected areas was certified under the “Better Cotton” scheme. Many major brands – like ASICS producing the Australian Olympic uniforms – have faced scrutiny for sourcing cotton from controversial regions.

Tracing global supply chains is hard. But the responsibility does not disappear just because it’s complicated.

In Australia, the Modern Slavery Act took effect in January 2019 to tackle issues such as forced labour and exploitation. Penalties include heavy fines or jail time.

However, there is a major loophole, as only companies with an annual revenue over A$100 million are required to report under the act. For big corporations, even if they are caught, the penalty can be tiny compared to the profits they have made.

This is not just an Australian problem, it’s global. For example, luxury brand Dior was placed under judicial administration after being found negligent for failing to act against worker exploitation in its subcontracted supply chain in Italy. The pattern is often the same; a company gets accused, sometimes even fined, but the cost is minimal compared to their annual revenue, so it’s barely a setback.

Is there a role for government?

So, should the responsibility rest only with brands? Not entirely. Governments also benefit from these companies through taxes and trade. They profit indirectly when the companies profit, and they benefit from the jobs these companies provide.

A stronger approach would involve government bodies and brands working with supply chain mapping companies, such as Textile Genesis, TrusTrace or FibreTrace. These platforms, often powered by blockchain and artificial intelligence, track a product through every stage of production.

Blockchain – which uses a decentralised database – can be a game changer.

Unlike websites or paper trails, blockchain data cannot be altered without leaving trace. Once recorded, the information is permanent, and it can be shared across manufacturers, brands and government bodies to maintain real-time disclosure.

When products enter a country, the ethical claims behind them could be verified in real time, instead of relying on brands to respond after an allegation is made.

The upfront cost is high and adoption might be slow. But in the long run it could save money on compliance, audits and damage control, while also building consumer trust.

Brands would still make profits, but consumers would have the confidence the products they are buying live up to the claims. Instead of government agencies being passive players, they would actively enforce that products meet the standards consumers expect.

In short, brands need to be held accountable, but so do governments. Greenwashing, modern slavery, and unethical sourcing will keep slipping through the cracks, unless they both work together.

The tools to make the fashion industry more transparent and honest already exist; it’s just a matter of using them.

Human-driven climate change threatens many species, including birds. Most studies on this topic focus on long-term climate trends, such as gradual rises in average temperatures or shifts in rainfall patterns. But extreme weather events are becoming more common and intense, so they warrant further attention.

Our new research shows extreme heat is having a particularly severe effect on tropical birds. We found increased exposure to extreme heat has reduced bird populations in tropical regions by 25–38% since 1950.

This is not just a temporary dip – it’s a long-term, cumulative effect that continues to build as the planet warms.

Our research helps explain why bird numbers are falling even in wild places relatively untouched by humans, such as some very remote protected tropical forests. It underscores the urgent need to reduce greenhouse gas emissions, to conserve the remaining biodiversity.

Digging into huge global datasets

We analysed data from long-term monitoring of more than 3,000 bird populations worldwide between 1950 and 2020. This dataset captures more than 90,000 scientific observations.

Although there are some gaps, the dataset offers an unmatched view of how bird populations have changed over time. Some parts of the world such as western Europe and North America were better represented than others, but all continents were covered.

We matched this bird data with detailed daily weather records from a global climate database that stretches back to 1940. This allowed us to track how bird populations responded to specific changes in daily temperatures and rainfall, including extreme heat.

We also looked at average yearly temperatures, total annual rainfall, and episodes of unusually heavy rainfall.

Using another dataset that reflects human industrial activity over time, we accounted for human pressures such as land development and human population density.

By combining all these sources of data, we created computer models to evaluate how climate factors and human impacts influence bird population growth.

Our research confirmed the work of other climate scientists showing extreme heat events have increased dramatically over the past 70 years, especially near the equator.

Birds in tropical regions are now experiencing dangerously hot days about ten times more often than they did in the past.

What we found: extreme heat is the biggest climate threat to birds

While changes in average temperature and rainfall do affect birds, we found the increasing number of dangerously hot days had the greatest effect – especially in tropical regions.

This is a major concern because tropical birds often have small home ranges and are highly specialised in terms of the habitats and climates they persist in. In many cases tropical birds exist within a small range of heat tolerance.

At temperatures beyond a bird’s limit of endurance, they go into hyperthermia, where their body temperature rises uncontrollably. In this state, birds may adopt a drooped-wing posture to expose more skin for heat loss, hold their beaks open and pant rapidly, spread their feathers, and become lethargic or disoriented. In severe cases, they lose coordination, fall from perches, or even collapse unconscious.

If they survive the experience, they can suffer long-term damage such as heat-induced organ failure and reduced reproductive capacity. Heat exposure reduces breeding success by lowering adult body condition and reducing time spent foraging – because the birds must rest or seek shade during the hottest hours.

It also causes heat stress in eggs and nestlings. In extreme events, nestlings may die from hyperthermia, or parents may abandon nests to save themselves.

Heat also increases a bird’s demand for water — not because they sweat (birds lack sweat glands) but because they lose water rapidly through evaporative cooling. This happens mainly via panting (respiratory evaporation) and, in some species, gular fluttering (rapid vibration of throat skin to increase airflow), as well as evaporation through the skin. As temperatures climb, these processes accelerate, causing significant dehydration unless birds can drink more frequently or access moister food.

Our study found that across tropical areas, the impact of climate change on birds is perhaps even greater now than the impact of direct human activities such as logging, mining or farming. This is not to say habitat destruction due to these activities is not a serious issue – it clearly is a major concern to tropical biodiversity. But our study highlights the challenges climate change is already bringing to birds in tropical regions.

A clear warning

Our research highlights the importance of focusing not just on average climate trends, but also on extreme events. Heatwaves are no longer rare, isolated incidents – they are becoming a regular part of life in many parts of the world.

If climate change continues unchecked, tropical birds – and likely many other animals and plants – will face increasing threats to their survival. Change may be too fast and too extreme for many species to adapt.

And as tropical regions host a huge share of the world’s biodiversity, including nearly half of all bird species, the ripple effects could be far-reaching.

Conservation strategies must take this into account. Protecting habitats from human industrial development remains important, but it’s no longer enough on its own. Proactive action to help species adapt to climate change needs to be part of wildlife protection plans – especially in the tropics.

Ultimately if we are to preserve global biodiversity, slowing down and eventually reversing climate change is essential. That means cutting greenhouse gas emissions, investing in ways to draw down existing carbon dioxide levels, and supporting policies that reduce our impact on the planet. The fate of tropical birds – and countless other species – depends on it.

As the annual humpback whale migration is underway with thousands of whales passing by the Australian coast, there are reports of dolphins joining the mass movement.

But this isn’t a one off. In fact, our new study, published today in Discover Animals, shows interspecies interactions between dolphins and whales are widespread and frequent around the world.

An astonishing interaction

There have been several reports of whale and dolphin interaction in the past.

One that astonished the public back in 2004 featured a humpback whale in Hawaii repeatedly lifting a bottlenose dolphin on its head.

Researchers suggested such close contact between whales and dolphins is likely very rare – and maybe related to care giving.

But other forms of interactions resembling joint feeding, play and harassment are now being frequently documented thanks to drone technology. Many are also featured on social media.

A ‘whale’s-eye view’ of the world

For our new study, we undertook an analysis of 199 independent whale-dolphin interaction events involving 19 different species. These interactions spanned two decades and occurred across 17 countries.

We drew from social media platforms – such as Facebook, YouTube and Instagram – and footage contributed by citizens to get a variety of observations.

Each entry was carefully reviewed to identify the species involved, validate the interaction and categorise behaviours. Two additional cases came from camera tags attached to humpback whales. These offered an underwater “whale’s-eye view” of their encounters with dolphins.

We categorised behaviours such as rolling, tail slaps, bow riding, and rubbing, and classified dolphin positions relative to whale body parts such as head, flank and tail fluke.

Having fun or fighting?

The study contradicted earlier assumptions that interspecies interactions between dolphins and whales are very rare.

The most common interaction was dolphins swimming near the whale’s head (akin to bow riding). This accounted for 80% of observed dolphin positions. Humpback whales were the most involved whale species, while bottlenose dolphins led the dolphin side.

Based on videos we analysed, dolphins initiated most interactions through bow riding, swimming in formation, or even touching whales.

In more than one-quarter of the events, the whales responded in seemingly similar ways. For example, humpback whales often rolled, exposed their bellies, or gently turned toward dolphins.

Tail slaps and other signs of distress or aggression were rare (roughly 5% of cases).

As a result of this, we classified more than one-third of all interactions between humpback whales and dolphins as positive or possible social play.

The two camera-tag videos revealed previously undocumented interaction. Dolphins were observed following humpback whales not only at the surface but down to the ocean floor. They maintained eye contact or even touched the whales’ head – suggesting intentional, possibly social, engagement.

Reflecting advanced emotional capabilities

The findings reshape our understanding of how social marine mammals interact across species. They suggest interspecies interaction among marine mammals may be far more prevalent and complex than previously believed.

Dolphins may seek out whales as companions for stimulation, play or even courtship-like behaviour. Meanwhile, certain whale species, particularly humpback whales, may not only tolerate but also engage with dolphins in a social capacity.

This interspecies dynamic adds a new dimension to marine mammal social ecology and could point to cultural elements in whale and dolphin societies. The playfulness, cooperation and apparent enjoyment observed in many interactions reflect advanced cognitive and emotional capabilities.

The study also demonstrates the power of new technologies and community science. Social media and drones proved invaluable for collecting a range of diverse behavioural data that traditional surveys might miss.

Social media data has limitations, such as geographic and observer bias caused by different angles, heights, equipment and frequency of use of social media. But it does complement other data and helps uncover previously unknown behaviours.

Whales and dolphins don’t just coexist but also seek each other out. Future studies incorporating acoustic recordings and longer observation periods could further unravel the motivations and meanings behind these fascinating encounters.

Prime Minister Anthony Albanese has announced Australia will recognise Palestine as a state at the United Nations leaders’ week in late September.

Unlike some other countries, the government has put no conditions on the recognition, relying on assurances received from the Palestinian Authority, the current Palestinian governing body in the West Bank.

Announcing the decision on Monday, Albanese said he had spoken to Israeli Prime Minister Benjamin Netanyahu last Thursday. In what Albanese said was a long call, Netanyahu argued the case against the proposed Australian action.

“I put the argument to him that we need a political solution, not a military one, because a military response alone has seen the devastation in Gaza, and that has contributed to the massive concern that we see from the international community,” Albanese said.

Albanese told a joint news conference with Foreign Minister Penny Wong “a two-state solution is humanity’s best hope to break the cycle of violence in the Middle East and to bring an end to the conflict, suffering and starvation in Gaza”.

Asked whether this was a symbolic gesture, Albanese said, “This is a practical contribution towards building momentum. This is not Australia acting alone. What we are seeing is a range of countries engaging in detailed dialogue.”

Albanese said that over the past fortnight, he had discussed the issue with UK Prime Minister Keir Starmer, French President Emmanuel Macron, New Zealand Prime Minister Chris Luxon and Japanese Prime Minister Shigeru Ishiba.

He also had a call last week with the Palestinian Authority President Mahmoud Abbas.

Albanese said the Palestinian Authority had committed to there being no role for Hamas in a Palestinian state and reaffirmed it recognised Israel’s right to exist, as well as making other pledges.

Shadow Defence Minister Angus Taylor said there is a risk the decision would be rewarding Hamas for its attacks on Israel on October 7 2023.

When asked earlier about such criticism, Albanese said “Hamas don’t support two states”.

“This is an opportunity to isolate Hamas, that has been forged by the very clear statements of the Palestinian Authority on June 10, and the very clear statements of the Arab League,” he said.

Before the announcement, Netanyahu strongly condemned the move.

He said it was “shameful” and “disappointing” that European countries and Australia would “march into that rabbit hole” and buy “this canard”. He made it clear Israel would not be deterred.

Asked about Australia and other countries moving to recognition, he said, “Well, first of all, those who say that Israel has a right to defend itself are also saying, ‘but don’t exercise that right’.”

He said Israel was applying force judiciously and “they know it”.

“They know what they would do if right next to Melbourne or right next to Sydney you had this horrific attack. I think you would do, at least what we’re doing – probably maybe not as efficiently and as precisely as we’re doing it.”

The Albanese government’s decision, which was reported to a cabinet meeting early Monday, followed years of pressure within the Labor party which has ramped up dramatically in recent months.

Wong spoke at the weekend to US Secretary of State Marco Rubio about Australia’s proposed course.

The Executive Council of Australian Jewry said in a statement about the announcement: “Israel will feel wronged and abandoned by a longstanding ally. The Palestinian Authority will feel that a huge diplomatic prize has been dropped in its lap, despite its consistent failures to reform, democratise and agree to peaceful coexistence alongside a Jewish state. Hamas and other Islamist groups will see that barbarity on a grand scale can lead to desired political transformation”.

Many people are familiar with the saying that a woman is “eating for two” during pregnancy. Although this is an exaggeration, nutritional needs do certainly increase during pregnancy to support the growing baby.

But what’s perhaps less known is that energy needs are actually even slightly higher during breastfeeding than during pregnancy.

Human breastmilk is a dynamic liquid and its composition (including carbohydrates, fats, proteins, vitamins and minerals) varies over the entire breastfeeding period, and even between feeds.

It can change depending on what mum is eating, environmental factors, and what the baby needs, through a biofeedback system (sometimes called “baby backwash”). For example, if a baby is starting to get sick, breastmilk will adjust to include more leukocytes, immune cells that fight infection.

So what should breastfeeding women be eating? And how does a mother’s diet influence the nutritional makeup of her milk?

Nutritional needs increase during breastfeeding

Fully breastfeeding mums can produce around 800 millilitres of milk a day in the first six months after birth, which has an energy content of roughly 3 kilojoules per gram.

Even factoring in using up excess fat stored during pregnancy, mums still need on average an extra 2,000 kilojoules to support milk production. This is roughly equivalent to adding a cheese sandwich, a handful of nuts and a banana on top of normal dietary intake.

Interestingly, requirements don’t drop off after the baby starts solids. In the second six months, milk production is thought to drop to an average of 600ml per day, as babies start to eat solid foods. But because maternal fat stores deplete by this stage, additional energy requirements remain similar.

Some nutrients are particularly important during breastfeeding, including protein, calcium, iron, iodine and vitamins.

For example, compared with a non-pregnant, non-breastfeeding woman, protein requirements increase by almost half when breastfeeding (from 0.75 grams to 1.1 grams per kg of body weight per day).

Meanwhile, iodine requirements almost double (from 150 micrograms per day to 270 micrograms per day). Iodine is important for thyroid function, and can impact baby’s growth and brain development.

It’s important women who are breastfeeding eat a variety of foods, including:

• high-protein foods (meat, fish, eggs, nuts, seeds, soy-based protein such as tofu and tempeh, legumes such as chickpeas, baked beans and lentils)
• dairy foods or alternatives (for dairy alternatives, check calcium is included)
• whole grains
• fruits and vegetables.

While making all that milk, drinking more water also becomes extremely important. Thirst is a good guide, but around 2.5 litres per day is generally recommended, or more if it’s hot or with exercise.

Is there anything I shouldn’t be eating?

What a mum consumes can pass into her breastmilk. For example, in one study, babies whose mothers drank small amounts of carrot juice while breastfeeding were more accepting of cereal flavoured with carrot juice compared with a control group of babies whose mothers drank water.

It’s therefore important to limit alcohol and caffeine, which can also pass though to the baby. No alcohol is the safest choice, but if you’re planning to have a drink, tools such as the Feed Safe app can be used to estimate when your breastmilk should be free of alcohol.

Up to 200mg of caffeine per day (equivalent to roughly a cup of brewed coffee, an energy or cola drink, or four cups of tea) is considered safe for breastfeeding.

Breastfeeding mums don’t need to take any particular foods out of their diet to prevent allergies in their baby. In fact, experts believe babies exposed to common allergens via breast milk could be less likely to develop allergies to these foods, however we need more research into this question.

Although relatively uncommon, babies can be allergic or intolerant to certain aspects of their mothers’ diet when breastfeeding. They may react in the form of colic or wind, reflux, mucus or blood in their poo, eczema or rash, or appear to be in pain.

In these cases, mum’s diet may need adjustment. The most common culprits include cows’ milk (the protein, not the lactose component), soy and egg.

It’s recommended to remove suspected foods from the diet for a minimum of three weeks. This should ideally be done with supervision from an Accredited Practising Dietitian who specialises in allergy, to ensure the mother’s nutritional needs continue to be met.

4 tips for breastfeeding mums

1. it’s a good idea to get a blood test to check your vitamin D and iron levels – these can be depleted over pregnancy and are important for breastfeeding. If your levels are low, you can discuss options with your doctor

2. iodine requirements are so much higher in breastfeeding that an iodine supplement of 150 micrograms a day is recommended to support infant growth and neurodevelopment

3. have a variety of nutritious snacks that can be eaten with one hand for those late-night feeds, such as peeled boiled eggs, a peanut butter sandwich on wholegrain bread, or avocado and cheese on a rice cake. My personal favourite is homemade rocky road with dark chocolate, nuts, seeds and dried fruit

4. keep a drink bottle with water nearby when breastfeeding.

If you’re considering a gift for a family with a new baby, remember new parents’ personal needs often take a back seat when bub arrives, including eating well. Consider a hearty frozen meal, muffins with oats and nuts, a nice stainless steel water bottle, gourmet trail mix or even some homemade rocky road.
