What are the human activities that causes environmental degradation?

Why is soil erosion caused by rain?
Soil erosion caused by rain occurs when rainfall hits the soil surface with enough force to dislodge and transport soil particles. This process is exacerbated by factors such as steep slopes, lack of vegetation, and soil compaction, which reduce the soil's ability to absorb and resist the impact of raindrops. Over time, repeated episodes of rain erosion can lead to significant loss of topsoil and degradation of soil quality.
What 4 human activities destroy soil?
Deforestation: Clearing forests for agriculture or development exposes soil to erosion and degradation. Overgrazing: Too many animals grazing in an area can lead to soil compaction and loss of vegetation, which exposes soil to erosion. Intensive farming: Practices like monocropping, excessive tilling, and heavy pesticide use can degrade soil health and fertility. Urbanization: Construction and development activities can lead to soil compaction, contamination, and loss of natural vegetation cover.
What are the 4 main causes of erosion?
The four main causes of erosion are water (such as rivers, streams, and rainfall), wind, ice (glaciers and freeze-thaw cycles), and human activities (deforestation, construction, and agriculture). These factors can contribute to the wearing away of soil, rocks, and other materials on Earth's surface.
What are 4 reasons arable and is decreasing?
Urbanization: Land is being converted for residential and commercial purposes, decreasing available arable land. Climate Change: Shifts in weather patterns and extreme events are affecting crop productivity and soil quality. Soil Degradation: Overuse of land, improper farming practices, and erosion are degrading arable land. Expansion of Infrastructure: Construction of roads, dams, and other infrastructure is encroaching on arable land.
