Текст
The problem starts here. cars burn petrol,factories and power stations burn coal and emit toxic fumes. so,the air that we breathe becomes polluted. this pollution is gathered in clouds and with the oxygen and water in the atmosphere it becomes acid. when it rains,this pollution lands on trees,houses,buildings,cars,clothes,everywhere!!!this is called acid rain when acid rain falls into lakes,streams,rivers and seas, they become toxic. this is water pollution and it harms kills or wipes out fish and plant species. the good news is that governments have been trying to reduce the air pollution that causes acid rain. some industries have been using new technologies for some time to help make factory smoke less harmful to the environment. but we need to do more. we can help reduce the amount of acid rain by using ours cars less or by using solar power to heat our homes.
