Question

in which of the following ways has the green revolution been unfriendly to the environment?
soil conservation
crop rotation

The introduction of new crop varieties can have positive effects like higher yields. However, the use of pesticides can harm non - target organisms (such as beneficial insects, birds, and aquatic life), contaminate soil and water, and lead to the development of pesticide - resistant pests, which are all negative impacts on the environment.
