Loss of forests causes dual problems. Trees are burned up and release huge amount of carbon dioxide gas into the atmosphere. On the other hand, when forests are cleared, an important storehouse of carbon dioxide is destroyed. Thus, the lose of forests causes dual problems.

To control the increase of greenhouse gases we should stop cutting down trees and burning fossil fuels like coal. mineral oil, natural gas, etc.

Forests help us by absorbing a lot of carbon dioxide from the air and deliver oxygen in exchange. They help to bring about rain and prevent soil erosion.

Yes, man can influence the climate. By cutting down trees and burning fossil fuels human creates greenhouse effect which influences the climate.

Humans can neither change the sun's radiation nor the earth's orbit around the sun because it is beyond the ability of human being. We do not have the power or ability to change the radiation of sun or the orbit of earth.

Human activities such as burning fossil fuels, industrial activities and cutting down trees cause more carbon dioxide emission in the atmosphere. Thus, human beings are responsible for the increase in the greenhouse gases.

The main cause of the increase in carbon dioxide level in the atmosphere is the burning of fossil fuels.

Enormous areas of forests are destroyed every year to obtain wood and to clear regions for mining and to create pasture.

Energy for factories was produced through the combustion of coal.

Humans are responsible for the increase of carbon dioxide in the atmosphere.

The carbon dioxide storehouse is destroyed with the forests as they absorb a lot of carbon dioxide form the airs and deliver oxygen instead.

Industrial revolution has given rise to so many factories.

About 85 million barrels of crude oil are used daily nowadays.

The carbon dioxide has increased in the atmosphere alarmingly in the last century.

Man can control the increase in the amount of greenhouse gases and its effects on the atmosphere.

Deforestation means destroying forest by felling and burning down trees.

According to the passage, changing the sun's radiation and changing the earth's orbit around the sun are beyond our means.

According to the passage, changing the sun's radiation and changing the earth's orbit around the sun are beyond our means.

(a) control (b) reason (c) accumulated (d) burnt (e) purposes

It is true that most of the natural phenomena are beyond humans' control, yet he can (a) control some aspects like the greenhouse effect by his wise activities. Carbon dioxide is the main (b) reason of it. Carbon dioxide is being (c) accumulated in the atmosphere by the burning of fossil fuels. In fact, industrial activities have given rise to many factories where coal is (d) burnt for energy. Moreover, mineral oil and natural gas are also used for various (e) purposes .

(a) increasing (b) producing (c) meet (d) afforestation (e) stake

So, it is our duty to stop cutting down trees indiscriminately. We should also inspire the general mass to plant more and more trees for our existence on earth. There are several reasons why the carbon dioxide concentration has been (a) increasing in the atmosphore. Our mills and factories burn coal, mineral oil. natural gas etc. with a view to (b) producing energy. We also burn these materials to (c) meet our everyday needs. But for our own safety, we have to encourage (d) afforestation . Otherwise our existence on earth will be at (e) stake .

(a) climate/ climatic (b) polluting (c) producing (d) fossil (e) major/main

Human beings are highly responsible for (a) climate/ climatic change. They are (b) polluting the environment by (c) producing greenhouse gases such as carbon dioxide, methane, CFC etc. Combustion of coal, burning of (d) fossil fuels, doforestation are the (e) major/main causes of pollution.
