We all love being with nature and enjoying the beauty of nature. But did we notice how often the climate is changing? Sometimes it's extremely hot, whereas sometimes it just starts raining suddenly. This is all due to the excess use of chemicals released out of the factories, rising temperature, more use of oil, gas, coal, and more carbon dioxide released in the atmosphere which warms up the earth. This is because on one hand - there is excess use of chemicals, harmful gases released out of the factories, burning more oil, gas, and coal which releases more carbon dioxide in the atmosphere. And on the other hand, destroying forests and not having enough trees to absorb that carbon dioxide. This results in rising temperatures and warms up the earth.
