Human beings cannot live on this earth without causing threat to nature essay
Answers
Answer:
Earth is home to millions of species. Just one dominates it. Us. Our cleverness, our inventiveness and our activities have modified almost every part of our planet. In fact, we are having a profound impact on it. Indeed, our cleverness, our inventiveness and our activities are now the drivers of every global problem we face. And every one of these problems is accelerating as we continue to grow towards a global population of 10 billion. In fact, I believe we can rightly call the situation we're in right now an emergency – an unprecedented planetary emergency.
We humans emerged as a species about 200,000 years ago. In geological time, that is really incredibly recent. Just 10,000 years ago, there were one million of us. By 1800, just over 200 years ago, there were 1 billion of us. By 1960, 50 years ago, there were 3 billion of us. There are now over 7 billion of us. By 2050, your children, or your children's children, will be living on a planet with at least 9 billion other people. Some time towards the end of this century, there will be at least 10 billion of us. Possibly more.
We got to where we are now through a number of civilisation- and society-shaping "events", most notably the agricultural revolution, the scientific revolution, the industrial revolution and – in the West – the public-health revolution. By 1980, there were 4 billion of us on the planet. Just 10 years later, in 1990, there were 5 billion of us. By this point initial signs of the consequences of our growth were starting to show. Not the least of these was on water. Our demand for water – not just the water we drank but the water we needed for food production and to make all the stuff we were consuming – was going through the roof. But something was starting to happen to water. Our emissions of CO2 modify our atmosphere. Our increasing water use had started to modify our hydrosphere. Rising atmospheric and sea-surface temperature had started to modify the cryosphere, most notably in the unexpected shrinking of the Arctic and Greenland ice sheets. Our increasing use of land, for agriculture, cities, roads, mining – as well as all the pollution we were creating – had started to modify our biosphere. Or, to put it another way: we had started to change our climate.

Explanation:
Human beings cannot live on this earth without causing threat to nature.
Human beings may be the most developed mammals on the earth but that doesn't mean he will be independent in his life. Contrarily, he is and need to be dependent on the other resources of nature for his livelihood.
Man cannot produce things on his own and has to depend on plants and other animals for his food and work. He 'employs' animals to help him in ploughing the fields and uses the plants as his food to sustain his life and also to keep himself safe from the outside environmental forces.
All of these are considerable as long as he makes sure to not over use them or exploit his usage. But as is the nature of men, even after using them in a sufficient manner, he still becomes greedy and keeps on using them. And he did not even think about the replenishing or replacement part of the process. If he had planted trees for the ones he cut, or takes good care of the animals he utilize, or even makes sure that the earth is clean and safe from pollution, he is maintaining the balance and keeping it in equilibrium. But rather than think of the balance, he just takes whatever he wants and utilizes them, content in his own happiness. Then, this leads to the exploitation of the very nature from which he gets his living, thus causing a threat to nature in the end.
