Read the passage and answer the questions

Humans can neither change the sun's radiation nor the earth's orbit around the sun. But they can control the increase in the amount of greenhouse gases and its effect on the atmosphere. Only during the last hundred years the carbon dioxide concentration has been raised alarmingly in the atmosphere and we humans can be held responsible for this.

The main cause of the increase in 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 required energy. which was produced through the combustion of coal. Besides coal, other sources of energy such as mineral oil and natural gas were also burned to heat our houses, run cars and airplanes or to produce electricity. Nowadays, about 85 million barrels of crude oil are burned daily. Every time a fossil raw material is burned, it releases carbon dioxide into the air,

Therefore, it is clear that more and more greenhouse gases like carbon dioxide are being generated worldwide by humans. Moreover, we are also strengthening the greenhouse effect by deforestation, which means cutting down trees. Every year enormous areas of forests are destroyed by people to obtain wood and to clear regions for mining and to create pasture. This loss of the forest causes dual problems. Trees that are burned up release large volumes of carbon dioxide gas into the air. On the other hand, as forests absorb a lot of carbon dioxide from the air and deliver oxygen instead, we also destroy an important storehouse of carbon dioxide when we clear forests.

উত্তরঃ

Trees help us in maintaining ecological balance in two important ways:

They absorb carbon dioxide from the air, which helps reduce the amount of greenhouse gases in the atmosphere.

They release oxygen into the air, which is essential for the survival of humans and animals.

By doing this, trees help control the greenhouse effect and keep the atmosphere healthy and balanced.

উত্তরঃ

The impact of fossil fuels on the atmosphere is that they release carbon dioxide, a greenhouse gas, when burned. This increase in carbon dioxide level strengthens the greenhouse effect, which contributes to global warming and climate change. The burning of fossil fuels like coal, mineral oil, and natural gas for energy, transportation, and electricity is a major cause of this problem.

উত্তরঃ

According to the passage, the things that are out of human control are:

The sun's radiation

The earth's orbit around the sun

These natural factors cannot be changed by humans.

উত্তরঃ

According to the passage, human beings can do the following things for a congenial (friendly and healthy) atmosphere:

Control the increase of greenhouse gases like carbon dioxide.

Avoid excessive burning of fossil fuels such as coal, oil, and natural gas.

Reduce deforestation by not cutting down trees unnecessarily.

Protect and plant more trees, as they absorb carbon dioxide and release oxygen.

By taking these actions, humans can help maintain a healthier and more balanced atmosphere.

উত্তরঃ

The passage teaches us that human activities, especially burning fossil fuels and deforestation, are major causes of the increase in greenhouse gases, which harm the atmosphere. We should take responsibility and take steps to reduce pollution and protect the environment for a better future.
