The correct options are
A To increase the yield of the crops
B To decrease the use of chemical pesticides
C To decrease the dependence on chemical fertilizers
The Green Revolution succeeded in obtaining high yielding and improved crop varieties. However, it was at the expense of ecological balance.

To prevent further pollution, scientists saw the need to make transgenic plants which were not dependent on these chemicals. At the same time, they sought to decrease the use of chemical pesticides while maintaining the high yield nature of the Green Revolution crop varieties
