Therefore, the question of wealth and health should attract great attention from the public so that they might make the balance.Is Stress a Bad Thing? 有压力是坏事吗Are you afraid of stress?

But water pollution exists not only in Taihu Lake but alsoin some other rivers, lakes and seas in our country.Without any doubt, water pollution is a serious problem today. Rivers, lakes and even oceans all over the world are being polluted by garbage and dangerous chemicals. Oil and other chemicals can kill fish and make water unsafe for drinking.More and more people have realized how serious the problem is.
