Humans cannot change the sun's radiation. But they can control the increase amount of carbon dioxide. The main cause of the increase of carbon dioxide level in the atmosphere is the burning of fossil fuels. Since the end of the 19th century, industrial activities increased rapidly giving rise to many factories. These factories use coal, natural gas to produce electricity. Nowadays, about 85 million barrels of crude oil are burnt daily. It produces carbon dioxide. Therefore it is clear that more and more greenhouse gases like carbon dioxide are being generated world wide by humans. Moreover, we are also increasing the green-house effect by cutting down trees. We cut down trees everyday to make fire, furniture and other purposes. As a result, carbon dioxide is increasing and oxygen is decreasing day by day.
Read and think about the questions.
1. Can man influence the climate? If the answer is yes, explain how?
2. Which human activities are responsible for increasing carbon dioxide in the atmosphere?
3. How can trees help to save our environment?
Comment your thought.. Thank you :-)
