Airborne DNA is a new frontier for studying ecosystems, monitoring species, and assessing conservation efforts.
Architecture can no longer be conceived as an isolated object, detached from the technical networks that sustain contemporary life. This condition calls for new readings and approaches.
The South Florida Reef Tract, once decimated by dredging in the 1950s, has bounced back, a resilient sign of hope in these ecologically depressing times.
Genetic sequencing has revealed that the state's nutria populations are most genetically similar to populations in Oregon, suggesting that California's current nutria invasion was the result of intentional reintroduction.
At a young age, I learned quickly how oil wealth and power could burn the land while people struggled. I saw heat rise off the streets, the Nile strained, and the air thickened with injustice. In my teenage years, through Aotearoa, being on the edge of the Pacific, I felt the ocean breathing heavy, swallowing the shores of islands that have done the least to cause this harm.
Around a third of UK gardeners use pesticides, and our studies found that house sparrow numbers, for example, were nearly 40% lower in gardens where the pesticide metaldehyde was used. By reducing pesticide use, you can actively encourage birds back into your outdoor spaces, as they rely on invertebrates such as slugs and snails as natural prey.
'Our results show that the next 20 years are critical,' lead author Dr Rob Cooke told the Daily Mail. 'By around 2050, we reach a point where the choices we make on emissions and land use will largely determine whether Britain moves towards a much more degraded or a much more nature‑positive future.'
If you enter the amounts of different types of plastic that you clean up into the Wildlife Impact Calculator, it will tell you how many animal lives would have been at risk, had those items made their way into the ocean and been ingested.
When British author Karen Armstrong won the TED prize in 2008, she used the money to convene a group of religious thinkers from a wide range of faiths to craft an updated version of the Golden Rule for the 21st century. What emerged was the Charter for Compassion, which calls on people around the world "to work tirelessly to alleviate the suffering of our fellow creatures, to dethrone ourselves from the center of our world and put another there, and to honor the inviolable sanctity of every single human being, treating everybody, without exception, with absolute justice, equity and respect."
Climate breakdown is occurring more rapidly with the heating rate almost doubling, according to research that excludes the effect of natural factors behind the latest scorching temperatures. It found global heating accelerated from a steady rate of less than 0.2C per decade between 1970 and 2015 to about 0.35C per decade over the past 10 years.
The question of how to protect fish and the ecological health of rivers that feed California's largest estuary is generating heated debate in a series of hearings in Sacramento, as state officials try to gain support for a plan that has been years in the making. "I am passionate that this is the pathway to recover fish," said state Natural Resources Secretary Wade Crowfoot. "This is the paradigm we need: collaborative, adaptive management versus conflict and litigation."
