Keep the planet safe

The global warming is a big problem that all of us should take into consideration if we want a better world. Everyday we can see how the pollution damages the environment and fauna and flora are being destroyed. So, what can we do to resolve these problem?

First of all, we have to reduce the CO2 emissions. For example, if everybody goes to work by bus instead of the by car we will cut down the car’s CO2 emissions. And It could be even better if we choose a bicycle or we just go walking.

Secondly, the rivers and seas need more attention. Generally, people use to throw things out regardless of what happens with to the animals which are living there.

Another point is the recycling*. Glass, paper and plastic must be recycled by everybody. For instance, we can take a bag with us when we go to the shop in order to not buying use** plastic bags.

To sum up, I believe that we can change the world by recycling and keeping rivers and seas clean. However, I would say that go walking everywhere is my best advice.

* This sentence is awkward. A simple change would be: "Another issue is recycling." but I think I would say something like: "Another way to help our planet is by recycling."

** I only changed this one because of a cultural disconnect. In the United States we don't purchase the bags and it would not make sense to most US citizens who have not traveled to Europe.

This is very good Advanced writing. You are able to talk about abstract topics in a way that the average native speaker would understand easily. Good job.
