So the wind and rain will dissolve or take away the bare soil. 7). Correct answer D. Now although the answer I put is correct, its not all that is correct. Erosion, compaction, nutrient imbalance, pollution, acidification, water logging, desertification, and fast-growing human population all contribute to the the reasons why Earth’s available agricultural land is being reduced. 9). Correct answer D. . Now although the answer I put is correct, its not all that is correct. Reduce overgrazing, limit herd sizes, killing invasive species, and leaving land unused for periods of time are all ways to sustain the productivity of rangeland. 10.) Correct answer C.

This is because typically when developing a nation the goal is to get a clean and small footprint, if they did have a larger and less ecological foot print the developing nation wouldn’t develop right. 37). The correct answer A. This is because Many causes have been cited for this collapse, including a lack of political will to impose adequate quotas, overoptimistic stock assessments by fishery scientists, poaching from foreign fleets, exceptional mortality from natural predators, climate change, subsidies to fishers, and overcapitalization. So therefore the knowing this information the answer would be A, the tragedy of the commons in open waters.
