How does agriculture affect the land?
Agriculture affects the environment in multiple ways. … When we clear land for agriculture, we often lose some soil. The plant species originally on this land are gone, and what we replace those with may be plants that aren’t as effective and retaining the soil and its nutrients. Thus, the soil degrades over time.
How does farming and agriculture affect water pollution?
The most prevalent source of agricultural water pollution is soil that is washed off fields. Rain water carries soil particles (sediment) and dumps them into nearby lakes or streams. … When these sources exceed plant needs, or are applied just before it rains, nutrients can wash into aquatic ecosystems.
How does agriculture cause greenhouse gases?
Airborne greenhouse gases are responsible for the effects of climate change. Carbon dioxide is emitted by farm equipment moving across the farm’s fields during tilling, planting, the application of pesticides and fertilizers and harvest. The more passes across the farm field, the more carbon that is emitted.
