Farmers, particularly those working on small farms, face soil antibiotic exposure risk, which is compounded by low income. Creating larger farms can reduce the exposure risks, but it might also limit employment opportunities for farmers. A global analysis suggests that establishing optimally sized farms in priority areas can help to balance exposure risks and farmer livelihoods.

Strategic planning has the potential to reduce the effects of mariculture on marine biodiversity. This approach can reduce the global biodiversity impacts of mariculture by up to 30.5% from 2020 levels, while meeting predicted global increases in demand for cultivated seafood of 1.82-fold for finfish and 2.36-fold for bivalves by 2050.

Second-generation oxidation boosts the production of anthropogenic organic aerosol, according to an analysis of urban haze in an experimental chamber.

As climate change and biodiversity loss intensify, the deep seabed beckons as a source of metals for batteries. Initiating this new exploitation conflicts with international agreements to decelerate biodiversity loss through wider protections of ecosystem integrity. The poor record of terrestrial mining must not be an excuse to mine the ocean floor. Improved oversight and biodiversity protection as miners increase production on land will produce a better global biodiversity outcome.

Only a holistic approach can help to mitigate the intensified global systemic environmental risks under climate change.

Margaret (95, UK) asks Dr Jennifer Harkness how pollution from fracking can impact local water quality.
