When it comes to environmental news, doom and gloom often rules the day. And it’s easy to get discouraged. But scientists from Yale University say most polluted ecosystems can recover in as little as 5 or 10 years.
The study means it’s not too late to turn things around if societies commit to cleanup, restoration and sustainability, according to Yale’s analysis of 240 independent studies. The findings appear in this month’s issue of the peer-reviewed journal PLoS ONE.

As the world approaches peak water, technology to harvest freshwater from non-potable sources becomes increasingly important. Researchers at Yale University have recently developed such desalination technology using the power of osmosis.
Zimbabwe, which currently faces seemingly intractable social, political and economic problems, has some of the worst environmental indicators in the world with ecosystems either in decline or under severe threat.
Suffice to state, the country did institute some good environmental protection programmes in the decade following the attainment of independence from British rule in 1980, markedly, Zimbabwe has about half of the world’s population of black rhinoceroses, an endangered species. During that period, the government even went as far as adopting a radical policy of shooting poachers on sight in order to protect endangered animal species.
In recent years, however, Zimbabwe has experienced desertification, soil and water pollution, slash and burn agriculture resulting in soil erosion mainly caused by an unplanned land resettlement programme initated by incumbent President Robert Mugabe’s government in 2000.
Yale University’s 2008 environmental performance index (EPI) which ranks 149 countries according to a weighting of carbon and sulfur emissions, water purity and conservation practices, positions Zimbabwe at number 95 thus highlighting the grim state of the environment in the country.
