Answer:
A. Higher standard of living for most people
The Green Revolution brought massive improvements in agriculture, which led to a great increase in food production that benefited most people around the world.
C. Pollution from fertilizers
The higher yields and output brought by the Green Revolution were facilitated by the extensive use of fertilizers in lands that are not as fertile/suitable for agriculture. This extensive use has also brought a new series of environmental problems.
D. Animal antibiotics and growth hormones
The Green Revolution was also manifested in the field of animal husbandry. In this field, antibiotics and growth hormones became commonplace for the same reason that fertilizers became commonplace in vegetable crops: increase output and productivity.
Answer:
c. Lack of food sources
Explanation:
The groundwater has been used more and more around the world. There are large reserves of it, but in the past few decades the groundwater reserves have constantly been going down. The main reason for this is the lack of food sources. Because the global population is constantly on the rise, more and more food is needed, and in order to produce it, more and more farmlands are created. The increased number of farmlands means that more water is needed for irrigation, thus the groundwater reserves are the ones that suffer the most.
