Hi Mazen,
There are many things that contribute to global warming. The largest problem has to do with animal agriculture. The amount of animals in factory farms creates the largest emissions of chemicals that affect the environment. Movies like Cowspiracy talk about this problem. If people changed their diet to be plant-based, the greenhouse effect would be greatly lessened. Here is a link to an article I just found: https://www.ciwf.org.uk/factory-farming/environmental-damage/#:~:text=As%20covered%20in%20our%20climate,increasingly%20hostile%20to%20live%20in
Each person can do their own part in helping to save this planet by eating a compassionate diet that is plant based and does not involve the killing of anyone. When we don't care about others, then we don't care about the environment either. When we have compassion for animals, the world's environmental problems will improve.
Another thing we can do to reduce chemical emissions is to take public transportation and carpool (or vanpool). A friend of mine works with a group of people who commute. They share in the cost of a rental van and take turns driving.
I hope that helps.
Thank You,
