15. Soil Degradation
Soil degradation, an urgent issue threatening our planet, is a major environmental problem that demands our attention. Our soil, a vital resource for food production and ecosystem health, is facing alarming degradation due to various factors. Let’s delve into the depths of this issue, understand its causes, and explore its consequences.
Causes of Soil Degradation
1. Erosion: Soil erosion occurs when the top layer of soil is washed away by water or blown away by wind, leaving behind bare and infertile land. This process is often intensified by unsustainable agricultural practices and deforestation.
2. Decline in Organic Matter: The continual removal of crops without replenishing organic matter leads to a decline in soil fertility. This reduction in organic matter disrupts crucial nutrient cycling processes and reduces soil’s ability to retain water.
3. Loss of Biodiversity: When soil ecosystems lose their diverse array of beneficial organisms, such as earthworms, bacteria, and fungi, their ability to maintain soil health and structure diminishes. Deforestation, intensive farming, and urbanization contribute to this loss of biodiversity.
4. Compaction: Human activities like heavy machinery use and constant traffic lead to soil compaction, which results in a decrease in soil porosity and a limited ability to absorb and store water.
