Final answer:
Climate change degrades soil primarily through increased erosion and desertification as a result of altered climate patterns and unsustainable land use. The environmental impact being discussed is soil erosion (Option C). This degradation poses significant risks to agricultural communities and food security.
Step-by-step explanation:
Climate change can degrade soil in multiple ways, but two significant methods are through increased soil erosion and desertification. Soil erosion occurs when changes in climate patterns, such as more intense and frequent rainfall or drought, strip away the top fertile layer of soil, reducing its quality and agricultural productivity. Desertification involves the transformation of fertile land into arid or desert-like conditions, often exacerbated by droughts and unsustainable land management practices prompted by climate shifts. The environmental impact being discussed in this statement is C) Soil erosion.
Addressing these impacts requires understanding the broader effects of climate change such as the increased frequency of extreme weather events, shifts in precipitation patterns, and changes in agricultural practices. Communities dependent on farming face heightened risks, as their livelihoods are intricately linked with soil health and climatic conditions. Implementing sustainable farming techniques and reducing greenhouse gas emissions are integral in mitigating soil degradation.
