    In view of the current food crisis, it is said, that we need another green revolution. Highlight the major limitations of the earlier green revolution.

Answer:

                    Majorlimitations of the earlier green revolution are as follows (i) Generally undesired characters also breed along with desired ones. (ii) Regular use of fertilizers affected both soil fertility and quality. (iii) Extensive use of pesticides/insecticides/weedicides resulted in harmful effects on the natural components of the ecosystem. So, another green revolution that can curb these problems and enhance the quality food production in limited land resources is certainly required.
