	A.	increase
	B.	become worthless
	C.	decrease
	D.	not change

29.

	D.	it is relatively easy to encourage countries to pay their share of pollution abatement costs.

30.

The largest form of greenhouse gases caused by human activity is:

	A.	methane gases from livestock farming.
	B.	carbon dioxide from the use of fossil fuel.
	C.	carbon dioxide from deforestation.
	D.	nitrous oxides from synthetic fertilizer usage.

31.

Which of these is not a major cause of greenhouse gas emissions?

	A.	deforestation
	B.	livestock production
	C.	soybean farming
	D.	burning fossil fuels

Answer 1

26. Today we are placing high value on a cleaner environment for future. Thus, it means the value of future is greater than the present.

A. The present value of future environmental benefits is lower.

28. If a government creates a market of tradable permits for greenhouse gases, the price of these permits would increase if environmentalists buy up permits to reduce the total amount of greenhouse gases.

Since, they have purchased the permits thus, less number of permits are available the prices would increase.

29. Global climate change is a global public good as it is due to the emission of greenhouse gases and all countries contribute cumulatively in increasing the overall concentration of these gases.

It may be noted that even though a country is not contributing to greenhouse gases but still they will be hampered by it. Similarly, even if a country is not working on to reduce global warming but the steps taken by other countries will improve them too. So, we can say climate change is associated with free rider problem.

30. The largest form of greenhouse gases caused by human activity is:

B. Carbon dioxide and use of fossil fuel.

We burn fossil fuel to fulfill our energy needs but in process of this a number of greenhouse gas is emitted that increases the global warming. We are majorly dependent on fossil fuels for our energy needs.

31. Due to deforestation the recycling of carbon dioxide decreases. As we know trees recycle carbon dioxide into oxygen. Thus it increases global warming.

More the livestock more will be the dung of the animals. This will increase the amount of methane in the atmosphere. Hence, this too increases greenhouse gas emission.

Burning fossil fuel is the major source of greenhouse gas emission.

C. Soybean Farming is not a major cause of greenhouse gas emission.
