could somebody check my writing? :D

Hi everyone! Look around and start saving our world!
I want to help our world because it is the place which is my home and import_ant places should be protect by habitants. My parents are ecofriendly and they support me and my plans.
Last week we started encourage people to reduce the amount of waste. People the most liked our campaign literatures which they had got. We told them that they should ride bikes often than cars.
My neighbors were very impressed my ecofriendly activity. They gave me a lot of money for it and it was very kind of them because donations helped me buy some banners.
I would like to encourage you to help our environment. Sometimes, you can sorting your rubbish or consuming less energy and it will be very much. If you want to join in the fun, you can contact me on the facebook.
I hope you will think it over!
