We found trade-offs among the environmental and animal welfare impacts of pig farms — those that had low greenhouse gas emissions typically had low land use but poor animal welfare and high antimicrobial use. Some farms performed well in all four impacts, but these farms were not consistently associated with any particular farm or label type.
A growing population, climate change and the environmental impacts of conventional agricultural practices are worsening food insecurity. New research shows that use of nanofertilizers can increase food production while simultaneously decreasing the negative environmental effects of agriculture.
Pollution by per- and polyfluorinated alkyl substances (PFAS) is widespread in global water resources and likely to be underestimated, according to global analysis of available PFAS data.
Critical clean energy materials exhibit supply risks due to unbalanced cross-country production and consumption patterns. A study now maps the global distribution of mineral property rights, through foreign direct investment, to show its potential role in reducing critical materials’ supply risks.
River sediments play a critical role in sustaining coastal ecosystems. This study examines patterns of coastal suspended sediment concentration (SSC) for 349 deltas worldwide via satellite images and investigated the possible driving factors.

Deep-sea mining could provide a substantial supply of metals that we urgently need to decarbonize our society, yet its environmental impact remains intractable. Considering on-land resources remain abundant and can be extracted using well-established risk management, deep-sea mining cannot currently be justified.

Policies and subsidies can help, and have helped, to establish the electric vehicle market. As subsidies are withdrawn and policies shift, the public will play a role in the future market infiltration.
