When something is free, people use a lot of it. Economists are urging governments to compute values for natural resources – wildlife, plants, air, water – to create motives for protecting them.
Wildlife populations have plummeted by 68% since 1970. But we have a plan to turn things around.
A new plan targets areas around the world that can store carbon and protect large numbers of species. It calls for preserving these lands, working with Indigenous peoples and connecting wild areas.
Framing cats as responsible for declines in biodiversity is based on faulty scientific logic and fails to account for the real culprit – human activity.
Evolution seems to lead to increasing complexity of species. But perhaps a dominant, intelligent species like humans will always end up destroying itself.
The risks to nature from man-made global warming – and the imperative to act – are clear.
300,000 years ago, there were lots of different species of human. Now it’s only us – and we're probably the reason why.
The conventional channels for scientists to inform and influence policy are not addressing the climate and ecological crises quickly enough.
Populations of plankton are in decline. If we push this critical foundation of the marine food chain to extinction, we could cripple ecosystems for millions of years.
Every cloud has a silver lining – even the debris cloud from an asteroid impact
Realising the silence of outer space was what made us appreciate our precarious position down on this pale blue dot – so beginning our obsession with extinction.
Not all of the solutions to the climate and ecological crisis have to be painful.
Growing evidence suggests that the extinction of the dinosaurs involved profound, complex and interconnected changes to the global systems that support life. Much like we are facing today.
Australia is losing mammals faster than any other country, as well as plenty more plants and animals besides. Extinction is theft from future generations – it's time to treat it as such.
Ecosystems can collapse suddenly and totally. Frozen zoos are trying to create archives of genetic material to prevent total extinctions.
The natural world depends on insects to function, but they may be the next casualty of climate change.
Death is inevitable for individuals and also for species. With help from the fossil record, paleontologists are piecing together what might make one creature more vulnerable than another.
Scientists believe since 2010 we have entered the sixth period of mass extinction. CO2 emissions will change the lives of plants and animals in the next three to four decades.
As much as one-third of animal species in the tropics could be eradicated if their habitats continue to be converted for monoculture farming. We can all do something to make a difference.
The planet has seen five 'mass extinctions' over the past half billion years, but each was followed by an explosion in biodiversity.
