How we can save the environment?

Saving the environment is an ongoing concern which many countries have to deal with. Fortunately, there are a number of possible solutions which could lead to permanent reduction in the air pollution that has grew up in countries around the world. To start with would be to plant more trees so that there is more oxygen. Trees are fresh and inhale the dirt from environment. So there would be at least fresh air. Another solution would be to use public transport or bicycles, then the air in cities would be a lot cleaner and less fuel would be wasted. Therefore there would be no anymore cars that pollute the air with their gas. For this reason everyone would be healthful as a walking or less stressful without using a car. One way would be that stricter laws should be put into effect to prevent factories from polluting the environment then both the air and water would be cleaner. Thus factories wouldn't trash and flow their dirt out. Clearly using less car, planting trees and stricter laws for factories are always work for the counties. All in all, there are many solutions to the problem of saving environment. The sooner these solutions are put into action, the more clean and safe earth would be in the world.
