Soil degradation and erosion - picture a lush, green field slowly turning into a dusty wasteland. This is the process where our soil loses its fertility and becomes less capable of supporting life. Like an overused car battery, the soil's productivity declines over time due to various factors.

Overgrazing

Ever watched a zombie movie where hordes of zombies consume everything in their path? Overgrazing is somewhat similar! When too many animals use the land, they munch away all the vegetation, leaving the soil bare and compacted. Imagine a herd of cows on a grass field, if left for too long, they'd eat up all the grass and trample the soil until it's as hard as concrete. This leads to less water seeping into the ground (infiltration), and more water flowing over the surface (overland runoff).

Over - cultivation & monoculture

Imagine being on a diet where you only eat burgers every day. Sounds cool at first, but your body will start lacking other essential nutrients. Similarly, when farmers grow the same crop (monoculture) on a piece of land repeatedly, it sucks out specific nutrients, causing soil fertility to decline. But there's a way around this problem, which is like having a balanced diet for the soil - by using polyculture or crop rotation, where different crops are planted in the same area at different times.

Deforestation

Think about the soil as a fragile piece of china and the vegetation as its packaging. Without its protective cover (like plant roots and canopy), the soil becomes more vulnerable and can easily break or in this case, get eroded. When forests are chopped down (deforestation), the soil is like a soldier without armor, ready to be swept away by wind and water.
