Question

why and how are our grasslands being converted to barren wastelands and cropland deteriorating​

Answer 1

Answer:

Our grasslands are being converted into barren wastelands, and croplands deteriorate. ... Over-grazing of animals has caused havoc to our grasslands. Similarly, the pressure of population on croplands has been affecting their productivity. Degradation of environment has led to such disasters.

Answer 2

Answer:

Just as over fishing affects fisheries, our grasslands are being destroyed for wood and for commercial purposes such as land to hold our ever growing population. Some grasslands are even being torn down to create croplands and farmlands. With each successive harvest, we reduce the fertility of the soil and the lands deteriorate, hence turning into barren waste lands.
