The impact of environment on society
Coal pollution
1 Not start the fire because when you burn trees or burn something it will make some smoke and if many people burn, burn and burn it will become the pollution. You can help by not burn trees.
2 When the factory let the smoke come out more, more and more so if it comes out many it will be pollution and they can help.
3 When you use the car it also will let the smoke come out from the car. If it just one car is just a little smoke but almost everyone that use the car so we need to help by using the bicycle.
