Who is hurt by air pollution?
The World Bank says air pollution is one of the worst environmental problems in large cities around the world. Air pollution causes breathing problems. It also threatens crop production in farm areas near huge cities.
The United Nations Environment Program says that air pollution reduces the amount of crops produced, h also reduces the nutrient level of crops. As a result, both the buyer and the seller of crops are hurt by air pollution.
The UN says dirty air is a major source of metal in crops. These metals include lead, zinc and copper. These metals can build up to dangerously high levels in the parts of plants that people eat. The German Appropriate Technology Exchange, GATE, reports that eating these metals can cause developmental problems and low intelligence levels among children. Some kinds of cancers and kidney damage have also been linked to metals in crops.
选项
A、The buyer.
B、The seller.
C、Both the buyer and the seller.
D、None.
答案
C
解析
从报道的“As a result,both the buyer and the seller of crops are hurt by air pollution.”可以看出,惟有C为正确答案,A,B都不全面。
