Why did Zimbabwe lose more than 1. 5 million hectares of forest in 2016? [origin

16. The forests in eastern Zimbabwe supply the country with wood and most of its fresh fruit. But the removal of large numbers of trees and use of fire to clear land have caused a lot or damage to the area. Officials say Zimbabwe lost more than 1.5 million hectares of forest in 2016. This is mostly because of local communities cutting the trees for firewood or setting fires in forested areas to make hunting easier.
17. With high inflation and food shortages across Russia, some Russians are growing their own vegetables. The country’ s struggling economy has kept food prices rising and put millions of people in poverty. In the Soviet Union, Russians who lived in traditional country homes—called dachas—often grew their own food. Today, many Russian families—including some in cities—are again growing food to deal with the hard economic times.
18. American scientists announced this week that genetically engineered food is generally safe for humans and the environment. They found that changing the genetics of what we eat does not carry the health risks that opponents claim. The Associated Press noted that the growth of genetically engineered crops has yet to lead to a jump in food production, as supporters claimed. The report did not find any conclusive evidence of environmental problems from such crops.
19. More than 700 million people worldwide have trouble getting clean, safe water. That number comes from the Water Project, a non-profit group. It estimates that one in nine people does not have access to safe and clean drinking water. Governments, non-governmental organizations and charities sent representatives to Stockholm, Sweden, earlier this month for World Water Week activities. The subject for this year’ s water week campaign was " water and waste, reduce and reuse. "
20. Several recent studies examined how machine automation and artificial intelligence will change the future of work. Some estimates predict these technologies could displace up to 30 percent of workers worldwide by 2030. One study predicted about 38 percent of American jobs could be at high risk due to automation by the early 2030s. In Germany, up to 35 percent of jobs could be at risk. About 30 percent could be affected in Britain and 21 percent in Japan.
