$\huge\bold\pink{SOIL\:EROSION}$

Soil erosion is a global matter of concern today. We cannot even list the benefits of proper fertile soil in one single article; such huge are its utilities. Let us just say that soil supports life on Earth. Plants, trees, humans, animals, micro-organisms everything grows on the soil. As if the soil pollution and soil contamination was not enough, the soil erosion has now increased and just added to our agony. If all the soil is eroded away, that day is not far away when there will be absolutely no soil left for us. Time for us to conserve soil along with all other forms of life on earth.

Soil erosion is caused by some factors. We cannot just blame human activities for the carrying away of soil particles. There are many natural reasons that lead to soil erosions. Factors like glaciers, surface runoffs, river and stream waters, lightning, exfoliation of rocks and several such factors lead to the erosion of soil. But well, humans cannot be left out completely. Around 40-50% of the soil erosion on earth is caused by humans and their irresponsible behaviors. Deforestation, improper farming techniques, intensive agriculture, construction of roads, bridges and dams all lead to soil erosion.

Enough said about what leads to soil erosion. But have you ever thought what can soil erosion lead to? What effects can soil erosion have on the earth? That’s what we are here to discuss today, the harmful and hazardous effects caused by soil erosion. Let’s have a look.

While it is true that intensive agriculture and improper farming methods lead to soil erosion, it is equally true that soil erosion affects further agriculture. When the soil is being eroded, it is not just the soil that is taken away, the minerals and nutrients that naturally occur in the soil are also carried away along with it. Soil erosion removes the topmost layer of the soil, which no doubt, is the most fertile and most productive part of any soil. When the top layer is removed, rills and gullies are formed in the soil.

The harmful effects of the removal of the topmost layer of the soil just do not end here. When the top layer is removed, the soil’s ability to store water and other nutrients are reduced. It also exposes the subsoil, which is the second layer of the soil. This subsoil has very poor physical and chemical properties.
