One of the big problems is the enviroment and pollution. Now a days every people through our cities and countries with our car. Doesn´t mind killing the enviroment. I would like to recommento you get the bus or underground, because the cities have lot of pollution. Public transport has advantages, for example, if you don´t earn lot of money, you should use the bus service, in stead of your car, because the bus service is cheaper tahn your car.

Talking from my own experience, I think these problems can be solved. I had finished work in the office when my friend John visited me. He wanted to visit the city, he loves sightseen, and w through the city by bus and underground and we didn´t need to my car. Every people could do it. On the contrary, other people prefer to use their car.

Pollution is a serious danger for river and seas. Let me conclude by saying that if you don´t take care the enviroment, river and seas will be dead. Not only is it bad for you also the future of the children.
