In this week’s episode of The Conversation Weekly, we speak with three scientists who study the ways plants and animals evolve in a world dominated by humans.
Brown carbon refers to a range of pollutants found in smoke from wildfires. They can contribute to global warming before they undergo a process that alters their chemical properties.
From persistent chemicals to exhaust particulate matter, snow accumulates highly toxic pollutants. Regulations are needed to address the impacts on water supplies and the food chain.
Billions of face masks and other personal protective equipment have been used throughout the pandemic. Containing plastic, these items are damaging wildlife and their environments.
UV absorbents and industrial antioxidants are used in many household goods to protect them from UV radiation. They can have an adverse impact on ecosystems.
Climate change is colliding with old factory sites where soil or water contamination still exist, and the most vulnerable populations are particularly at risk.

A 1972 report warned that unchecked consumption could crater the world economy by 2100. Fifty years and much debate later, can humanity innovate quickly enough to avoid that fate?
This Plastic Free July, we need to be teaching children to demand less plastic from the world’s worst producers instead of expecting change from individual recycling efforts.

Thanks to humans, the concentration of planet-warming carbon dioxide in the atmosphere is now 50% higher than before the industrial era. These gases are raising Earth’s temperature.

A new study of dairying in Canterbury shows previous estimates vastly underestimate the impact of intensive farming. A 12-fold reduction in cow numbers could be needed to meet safe water standards.
