English...writing about environment

I believe in the world should be a clean and safe planet for all of us. How can we have take care of this amazing world?

Firstly, how many of us go to do their daily tasks in using a bike or other public transportation?
Only a few prefer to move on clean and zero CO2 emission transportation to commute to their jobs, houses, events... etc.
What is the main reason for lots of people do choosing not to use green vehicles? I think most people prefer the of commodity and fast speed of their own cars to move everywhere. But what happens with this way of living?...Maybe many of them do not know their city the city where they are living because of their use of cars. or Another result may be that they do not use to do exercise because of the lack of energy to walk, run or move without artificial energy as a car or motorbike.

This last statement is a little unclear. It is not necessarily incorrect, but another way you could say it may be: "they feel that there is no need to because cars do it for them".

Secondly, I try to understand why society does not open their mind to realize the real problem as the climate changes, to give up the CO2 emission transportation. We are in the worse period of time in Earth with higher levels of CO2 in the The levels of high CO2 are worsening in Earth's atmosphere. If we walk and ride our bikes everyday, we will change the planet's climate. Perhaps we still have time to change it before it would be is too much late.

To sum it up...the climate change is a reality and we can move our bodies to survive on this planet!!!

(Thanks so much if someone could help me to correct my mistakes...I suposse they would be lots...really thanks!!!)
