Human need and greed is indeed causing the extinction of nature. As the only species on Earth who has ever had the capacity to exploit the planet in such a way, we are responsible for more destruction of habits and animals than any living creature on the planet. Hopefully, we can use that same ingenuity to reverse some of our damage.
Day by day the needs of human beings are increasing. As we are totally dependent on nature so as our population is growing our need is also growing. We are using all the resources of nature and due to this nature is going towards extinction. If we shall not stop this extinction then our existence will be in danger.
