Nut, we greedy humans have exploited its resources to such an extent that even the most essentials are not available to some people. Being responsible inhabitants of this planet, we must take some measures to reverse the damage caused to our planet. It has seen a lot of exploitation. We have been cutting trees recklessly for our use. For every tree lost, the Earth loses a part of itself. We must plant as many trees as we can in our limited lifetimes, to bring the previous lush green forests back to life. If we can all plant a sapling each, every year then, the Earth will be filled with nearly 7 billion trees in one year."
