Sentient Media reveals less than 4% of climate news stories mention animal agriculture as source of carbon emissions
Five of the seven breached planetary boundaries are linked to food systems. By transforming production and adopting a “planetary health diet,” we can halve food-related climate emissions and prevent millions of deaths, according to the 2025 EAT-Lancet Commission.

Exclusive: Increasingly extreme weather a threat to production and supply chains in Britain and elsewhere

juin 2025

Even if agricultural practices adapt in response to higher temperatures, five of the world's six main staple crops will suffer severe losses due to climate change. Global corn yields are projected to fall by about 12 or 28 per cent by the end of the century

Acute global food insecurity rose for the sixth year in a row in 2024, according to the 2025 Global Report on Food Crises (GRFC), a collaborative effort coordinated by the Food Security Information Network. The report shows that climate extremes, conflict, forced displacement and economic shocks continue to drive malnutrition and food insecurity around the world, with disastrous impacts on those living in many of the most vulnerable regions in the world.

Eat-Lancet report recommended shift to more plant-based, climate-friendly diet but was extensively attacked online [...] The report recommended that if global red meat eating was cut by 50%, the “planetary health diet” would provide nutritious food to all while tackling the harms caused by animal agriculture, which accounts for over 14% of all greenhouse gas emissions worldwide. It suggested individuals – particularly in wealthy countries – should increase their consumption of nuts, pulses and other plant-based foods while cutting meat and sugar from their diets.

The world could fall short of food by 2050 due to falling crop yields, insufficient investment in agricultural research and trade shocks, according to Joe Biden’s special envoy for food security, Dr Cary Fowler. Fowler, who is also known as the “father” of the Svalbard Global Seed Vault, a global store of seeds for the most significant crops, said studies by agricultural economists showed the world needed to produce 50-60% more food by 2050 in order to feed its growing population. But crop yields rates were projected to decline by between 3-12% as a result of global heating.

décembre 2024

Depleted soil leads to reduced yields, forcing farmers to rely on fertilizers that raise food production costs, consumer prices.
Microplastics and nanoplastics may be present in food, primarily from environmental contamination where foods are grown or raised.

août 2024

High-level policy discussions have built momentum for “food system transformation” that would help farmers address the climate crisis.

Simultaneous harvest failures across major crop-producing regions are a threat to global food security. Concurrent weather extremes driven by a strongly meandering jet stream could trigger such events, but so far this has not been quantified. Specifically, the ability of state-of-the art crop and climate models to adequately reproduce such high impact events is a crucial component for estimating risks to global food security. Here we find an increased likelihood of concurrent low yields during summers featuring meandering jets in observations and models. While climate models accurately simulate atmospheric patterns, associated surface weather anomalies and negative effects on crop responses are mostly underestimated in bias-adjusted simulations. Given the identified model biases, future assessments of regional and concurrent crop losses from meandering jet states remain highly uncertain. Our results suggest that model-blind spots for such high-impact but deeply-uncertain hazards have to be anticipated and acc

After hottest day ever, researchers say global heating may mean future of crop failures on land and ‘silent dying’ in the oceans
Climate breakdown and crop losses threaten our survival, but the ultra-rich find ever more creative ways to maintain the status quo, says Guardian columnist George Monbiot

Recycled and reused food contact plastics are “vectors for spreading chemicals of concern” because they accumulate and release hundreds of dangerous toxins like styrene, benzene, bisphenol, heavy metals, formaldehyde and phthalates, new research finds.

the biophysical limits of food production are being reached. Second, current food production systems are actively destroying the very resource base upon which they rely. Third, the majority of food production and all its storage and distribution is critically dependent upon fossil fuels, not only making the food supply vulnerable to price and supply instability, but also presenting an impossible choice between food security and reducing greenhouse gas emissions. Fourth, climate change is already negatively impacting the food supply and will do so with increasing intensity as the Earth continues to warm and weather destabilises. Fifth, the trajectory of increasing food demand that cannot easily be reversed. Sixth, the prioritisation of economic efficiency and profit in world trade has undermined food sovereignty and the resilience of food production at multiple scales, making both production and distribution highly vulnerable to disruptive shocks. Considered individually, each one of the hard trends presents a
