Why can humanis neither change the sun's radiation nor the earth's orbit around the sun?

Human beings are largely responsible for the alarming increase in greenhouse gases, primarily through two major activities: the burning of fossil fuels and deforestation. Since the end of the 19th century, industrial expansion has rapidly increased the combustion of coal, mineral oil, and natural gas to power factories, heat homes, run vehicles, and generate electricity, all of which release massive amounts of carbon dioxide into the air daily.

Moreover, humans strengthen the greenhouse effect by widespread deforestation, which involves cutting down and often burning trees to obtain wood, clear land for mining, or create pastures. This practice not only releases stored carbon dioxide when trees are burned but also destroys an essential natural "storehouse" that absorbs carbon dioxide from the atmosphere and delivers oxygen, further contributing to the imbalance of greenhouse gases.

According to the passage, the main cause of the increase in carbon dioxide level in the atmosphere is the burning of fossil fuels.

The passage details that industrial activities, rapidly increasing since the end of the 19th century, required vast amounts of energy produced through the combustion of coal. Moreover, other fossil fuels like mineral oil and natural gas are extensively burned to heat homes, power cars and airplanes, and generate electricity, all contributing to the release of carbon dioxide into the air.

Furthermore, the passage clearly states that humans intensify the greenhouse effect through deforestation, which is the cutting down of trees. This practice creates a dual problem: trees that are burned release large volumes of carbon dioxide, and the destruction of forests eliminates a crucial natural absorber of carbon dioxide, thus significantly boosting its concentration in the atmosphere.

Enormous areas of forests are destroyed by people every year due to several human activities that prioritize immediate needs over environmental sustainability.

As stated in the passage, people destroy vast forest areas primarily for three main reasons: to obtain wood for various purposes, to clear regions for mining activities to extract valuable resources, and to create pasture land for livestock grazing. These actions are often driven by economic motives and the growing demands of an increasing global population.

This widespread deforestation leads to a dual problem that significantly impacts the environment. Firstly, when trees are burned to clear forests, they release large volumes of carbon dioxide gas into the atmosphere, contributing to the greenhouse effect. Secondly, forests naturally absorb a significant amount of carbon dioxide from the air and release oxygen. Therefore, by clearing forests, humans destroy an essential natural storehouse of carbon dioxide, further exacerbating the problem of increasing greenhouse gas concentration.

In essence, the destruction of forests is a direct consequence of human activities aimed at resource extraction and land conversion, leading to critical environmental issues like increased carbon dioxide levels and the strengthening of the greenhouse effect.
