They have been developing a range of scientific tools, from maps and models to air-pollution sensors, to assess the cumulative burden of environmental and social injustices. It now falls to US researchers, activists and policymakers to work out the details of what ‘environmental justice’ really looks like. These could include poor neighbourhoods near polluting industrial facilities, for example. Reference: Proceedings of the National Academy of Science paper The science of environmental justiceĪ key policy of US President Joe Biden’s administration, the Justice40 initiative, pledges that 40% of the government’s investments in climate and clean energy will go to disadvantaged communities. With those land-management practices curtailed by settler colonialism, the tree density in parts of the Klamath Mountains is at a record high, and at risk of serious wildfires. Combined, the evidence shows how cultural burning - small, controlled fires that keep biomass low and reduce the risk of more widespread burning - promoted stability in the forests of the Klamath Mountains for at least 1,000 years. And by analysing sediment cores from lakes, researchers inferred tree density and the amount of fire in the area at various times. Nature | Leisurely scroll How to turn a forest into a tinderboxĪ 3,000-year history of a large fire-prone forest in California has been reconstructed with the help of traditional ecological knowledge shared by members of the Karuk, Yurok and Hoopa Valley Tribes.

After being measured and weighed by a rescue team, the ray was released unharmed back into the river. The 4-metre-long Urogymnus polylepis was captured after it swallowed a smaller fish on a baited hook. Stunned fishers came face to face with this giant freshwater stingray after accidentally hauling it up from the murky depths of the Mekong River in Cambodia.
