Understanding Greenhouse Gases
Greenhouse gases (GHGs) are components of the Earth's atmosphere that trap heat, contributing to the greenhouse effect, which is essential for maintaining the planet's temperature. Among the various GHGs, the question highlights three significant ones: CO2, N2O, and CH4.

1. Carbon Dioxide (CO2)
- CO2 is the most prevalent greenhouse gas produced by human activities, primarily through fossil fuel combustion, deforestation, and various industrial processes.
- It has a long atmospheric lifetime, which means it can remain in the atmosphere for hundreds of years, significantly influencing global warming.

2. Nitrous Oxide (N2O)
- N2O is released during agricultural activities, particularly through the use of nitrogen-based fertilizers, as well as from fossil fuel combustion and certain industrial processes.
- This gas has a much higher global warming potential (GWP) than CO2, making it a potent contributor to climate change.

3. Methane (CH4)
- CH4 is released during the production and transportation of coal, oil, and natural gas. Additionally, it comes from livestock and other agricultural practices, as well as from the decay of organic waste in landfills.
- Methane has a GWP significantly greater than CO2 over a 20-year period, highlighting its impactful role in short-term climate change.

Conclusion
- Each of these gases contributes to the greenhouse effect in different ways, making option 'D'—“All of these”—the correct answer.
- Understanding these gases and their sources is crucial for developing strategies to mitigate climate change and reduce their impact on the environment.

Similar Commerce Doubts

Read the following passage and answer the questions that follows:In economics, rationing is an artificial restriction of demand and is done to keep price below the equilibrium (market-clearing) price determined by the process of supply and demand in an unfettered market. Thus, rationing can be complementary to price controls which can be explained through indifference curve approach.There are two kinds of rationing done by the government to reduce consumption—price rationing and non-price rationing. By rationing, we mean exercise tax and by non-price rationing, we mean all types of control on the quantity consumed. Non-price rationing could be done by giving away coupons that would enable low income families to obtain some goods at affordable prices, which could not be possible if the prices were to increase alone. With coupon schemes, it would develop a black market for coupons, which would paradoxically increase the utility for those who are in need of that commodity by collection of more of these coupons from those who are not in need. This ensures greater marginal utility for those people who are in need of the commodity and will provide exchange of money to those who sell these coupons. For this, it is necessary for the government to encourage trading of the coupons.The major importance of introducing rationing is to keep the price of important commodities under control, as for a necessary commodity, there will be an excessive demand in the market which will drive their price up in the market and high prices leads to reduction of consumption and utility for those who could not afford it. This ensures that the resources are planned in favour of the poor people of the country and restricts the rich people to ensure excessive purchase of limited resources of the country. This ensures development and equality of welfare and utilitybetween the rich and the poor people. Rationing of the good is done by the government and not the private sector. There is the same limit put on every person on the budget spending to which people could buy the commodities and within the limit, one could buy any amount of the commodity.Q.
