Hope this helpsWe must look after the world – it is our home
(In) These days, the world is a place in which one has to cope with global warming, changing climate, natural disasters, pollution, acid rains and endangered species.
Some people claim that protecting nature is unnecessary. They believe (that when one) letting nature follow its own course, (it) is better than interfering (with them.) They think that interference is unnatural and it is a wrong way.
However, other people believe that this opinion is erroneous. Every person can contribute to saving the planet. If one wishes to breathe clean air, one should reduce (using a) car usage because of pollution. By using public transport, car sharing, walking or biking/cycling (to get) to work and around and about, one can improve ones level of fitness as well as the state of the environment.
To sum up, it seems to me that protecting nature is really neccessary. (And) Every person should care about the environment (as he cares) in the same way as caring about the home, because the environment is our biggest home.
