An introduction to global warming

There are many controversial issues in the world today. We are going to look at the issue of global warming. In the following, I am going to outline some causes and effects concerning the topic.
First of all, let’s talk about the causes of global warming. The pores in the ozone layer are the main reason for the global warming. The holes are caused mainly because of pollution. The use of petrol in our day to day life makes the problem even bigger. Petrol and coal is used in factories and industries commonly and a lot.
So we have to do something to solve this important problem. Why we shouldn’t make a green environment free of polluting agents? I think we have to use green cars which do not pollute our environment. An important point to take note of is that we can make our world better by looking for other alternative and non-polluting sources of energy. Such as solar energy and wind power and try to make them better.
Finally, global warming is a serious issue that we have to collaborate and solve. We have to try and teach people more about the importance of our environment.
