Why is the lost of topsoil great concern?

The loss of topsoil is a great concern because topsoil is crucial for supporting plant growth and providing nutrients for crops. Loss of topsoil through erosion can lead to decreased agricultural productivity, increased water runoff and sedimentation in water bodies, and reduced ability to sequester carbon from the atmosphere, contributing to climate change. It can also lead to desertification and land degradation, impacting food security and ecosystem health.
