Major study finds world's most productive farming regions are especially vulnerable to rising temperatures, and face steep declines in agricultural output this century.
A new point in history has been reached, entomologists say, as climate-led species’ collapse moves up the food chain even in supposedly protected regions free of pesticides
Antarctica's remote and mysterious current has a profound influence on the climate, food systems and Antarctic ecosystems. Can we stop it weakening by 2050?
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.
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.
High-level policy discussions have built momentum for “food system transformation” that would help farmers address the climate crisis.

Existing production destroys more value than it creates due to medical and environmental costs, researchers say
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
Potential external cost savings associated with the reduction of animal-sourced foods remain poorly understood. Here we combine life cycle assessment principles and monetarization factors to estimate the monetary worth of damage to human health and ecosystems caused by the environmental impacts of food production. We find that, globally, approximately US$2 of production-related external costs were embedded in every dollar of food expenditure in 2018—corresponding to US$14.0 trillion of externalities. A dietary shift away from animal-sourced foods could greatly reduce these ‘hidden’ costs, saving up to US$7.3 trillion worth of production-related health burden and ecosystem degradation while curbing carbon emissions. By comparing the health effects of dietary change from the consumption versus the production of food, we also show that omitting the latter means underestimating the benefits of more plant-based diets. Our analysis reveals the substantial potential of dietary change, particularly in high and upper-
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.

Fourth year in a row in which number of people facing food crises increased substantially
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
The excessive use of phosphorus is depleting reserves vital to global food production, while also adding to the climate crisis
Ecosystems rely on interconnectedness — bees pollinate the flowers, predators eats prey, and so on. But these webs, though highly evolved, can be delicate. One link goes missing, and a ripple effect is felt throughout the entire system. As more species are lost, that balance becomes increasingly fragile, sometimes to the point of collapse.
The coasts of Alaska are piled up with dead birds dying of starvation. Experts say that climate change is resulting in shifts in the food chain.
