Explanation:

Statement 1 and 2: This was due to increased use of chemical fertilizers. Also, continuous use of groundwater for tube well irrigation has reduced the water-table below the ground.

Statement 3: An absurd statement. In fact, many HVVs helped reduce fungal infections.

Statement 4: Seed Replacement Ratio is a measure of how much of the total cropped area was sown with certified seeds in comparison to farm saved seeds.

This has certainly increased post green revolution as farmers started using certified seeds more and more.
