Résumé
The world faces substantial environmental challenges - climate change, pollution, and extinction. But the good news is that we have solutions to these problems. In the past 50 years, a remarkable number of environmental problems have been solved, while substantial… progress is ongoing on others: endangered species pulled back from the precipice of extinction; thousands of new parks, protecting billions of hectares of land and water; the salvation of the ozone layer, vital to life on Earth; the growth of renewable energy powered by wind, water, and sun; remarkable strides in cleaning up the air we breathe and the water we drink; the banning of dozens of the world’s most toxic chemicals. Past successes will pave the way for even greater achievements in the future. 2015.
