Překlad do angličtiny

Za ukol jsem měli napsat slohovku ,,I i ruled the world,, , mohl by prosím něko zkontrolovat chyby ? děkuju :D
If i ruled the world

If i ruled the world, the first thing I'd do is prevent global warming. In my opinion, that's one of the most serious problems we face. I'd reduce petrol powered car and I'd use alternative sources.
I'm convinced that it could help to limit global warming. I'd also ban terrorism and ensure world peace, because I think the world peace is the most important for everyone. I’d also prevent famine. In my opinion the famine is next serious problem. I am convinced that if we have enough foods, we will have a better life.

The next thing I would do is to ban drugs and cigarettes. At the first it is expensive and the second it’s very unhealthy. I want make smokers to stop with smoking. Of course, I don’t believe that smokers will be happy, but I will make sure them that without smoking will life nicer.

There are some less serious things I would do too, for example I'd ban rap music I think it's terrible. Finally, I'd make television advertising because I think it's annoying.
