Explanation:
The benefits of preserving the nature is bigger than the costs of preserving nature. All we need to do is understand and educate ourselves how important nature is to all living beings on Earth. Preserving the nature would mean that there would be a healthy Earth for all generations to come in the future. There would be clean air, beautiful landscapes and cool breeze on Earth.
As predicted by researchers, Earth will not last for another hundred years if we keep on polluting and harming it. The time has come to take big measures and preserve the nature. Every individual is responsible in this task and all we need is a commitment to build an environmental friendly world.
