Which of the following factors is contributing to Global Warming?

1. Burning of coal
2. Deforestation
3. Methane gas released in animal waste
4. Use of fossil fuel
5. Use of Hydropower

Choose the correct answer from the options given below:

(A), (B), (C) and (D) only

The correct answer is: Option 3: (A), (B), (C) and (D) only

Here's why:

Burning of coal: This is a major contributor to global warming. Coal releases greenhouse gases like carbon dioxide when burned, trapping heat in the atmosphere.
Deforestation: Forests absorb carbon dioxide, a significant greenhouse gas. Deforestation reduces this natural absorption capacity, contributing to rising global temperatures.
Methane gas released in animal waste: Methane is another potent greenhouse gas. While not the biggest contributor, methane from animal agriculture does play a role in global warming.
Use of fossil fuel: Burning fossil fuels like oil and natural gas releases greenhouse gases, similar to coal.
Use of Hydropower: Hydropower is a renewable energy source and does not contribute to global warming. It produces electricity without releasing greenhouse gases.

"Global warming is a gradual increase in the average temperature of the earth’s lower atmosphere as a result of the increase in greenhouse gases since the Industrial Revolution. It is caused by man-made increases in carbon dioxide and other greenhouse gases through the burning of fossil fuels and deforestation. Adding carbon dioxide, methane and such other gases (that have the potential to absorb heat) to the atmosphere with no other changes will make our planet’s surface warmer. Among factors that may be contributing to global warming are the burning of coal and petroleum products (sources of carbon dioxide, methane, nitrous oxide, ozone); deforestation, which increases the amount of carbon dioxide in the atmosphere; methane gas released in animal waste; and increased cattle production, which contributes to deforestation, methane production, and use of fossil fuels. Hydropower is more environmentally friendly as compared to other significant sources of electrical power that rely on fossil fuels. In contrast to fossil fuel-powered facilities, hydropower plants do not release the waste heat and gases that are significant contributors to global warming."
