Unsustainable exploitation of the natural world threatens food and water security of billions of people, major UN-backed biodiversity study reveals.
Human destruction of nature is rapidly eroding the world’s capacity to provide food, water and security to billions of people, according to the most comprehensive biodiversity study in more than a decade.
The rate of decline is moreover accelerating. In the Americas – which has about 40% of the world’s remaining biodiversity – the regional population is gobbling up resources at twice the rate of the global average. Despite having 13% of the people on the planet, it is using a quarter of the resources, said Jake Rice, a co-chair of the Americas assessment.

Wind, solar, and storage could meet 90–100% of America’s electricity needs.
The authors found that with 100% power capacity and no mechanism to store energy, a wind-heavy portfolio is best (about 75% wind, 25% solar) and using large aggregate regions is optimal. It is possible to supply about 75-80% of US electrical needs. If the system were designed with excess capacity (the 150% case), the US could meet about 90% of its needs with wind and solar power.
The use of clean energy to power an entire country (or a group of countries) is achievable. It’s no longer viable to say “we can’t.”

Climate change is profoundly unfair: By failing to address it, today’s leaders are imposing what could prove to be an unbearable burden on future generations. But how can they be made to recognize the danger and act? Using the U.S. legal system, a group of children has found a novel way to do so.
