Question

what is one way intensive agricultural practices contribute to climate change?

a. tree loss to agriculture increases the land’s albedo.

b. certain methods of plowing release greenhouse gases.

c. livestock manure absorbs greenhouse gases.

d. fewer trees are available to replenish petroleum stores.

Explanation:

• Option A: Tree loss for agriculture typically decreases albedo (more absorption of solar radiation), so A is incorrect.
• Option B: Intensive plowing methods (like tillage) can disturb soil, releasing greenhouse gases (e.g., CO₂, methane) from soil organic matter, contributing to climate change. This is correct.
• Option C: Livestock manure produces greenhouse gases (e.g., methane) rather than absorbing them, so C is incorrect.
• Option D: Trees don't replenish petroleum stores (petroleum is a fossil fuel from ancient organic matter), so D is incorrect.

Answer:

B. Certain methods of plowing release greenhouse gases.
