To decrease the use of coal and protect the environment,there are multiple solutions we can use.First,we could stop cutting down trees and plant more trees,which decrease the production of coals.Second,we can save energy in our daily life by taking bick or public transportation,rather than driving a car.We can also limit the emission of the exhaust of vihicles by making certain laws of vihicles' production.In addition,we can use some other energy source to replace the coal.For instance,we can use clean energy,such as solar energy and wind energy.
Through these ways,I believe we could bring a change to the environment and make the world better!
