Scientists are using biotechnology to improve the efficiency of cow milk production. Using this technology, a dairy farmer
obtains the same amount of milk while using only 90% as many cows. Which of the following statements predicts the most
likely environmental impact of this technology?
The amount of grain consumed by each cow will decrease.
The amount of waste produced by each cow will decrease.
The amount of land required for raising cows will decrease.
The amount of gas required for transporting cows' milk will decrease.

Biotechnology in dairy farming can lead to reduced waste production per cow, decreased land usage for raising cows, and potential environmental benefits by lowering greenhouse gas emissions.

Explanation:

The amount of waste produced by each cow will decrease. Biotechnology advancements in dairy farming can lead to more efficient milk production, potentially reducing the waste generated per cow. This improvement could have a positive environmental impact by decreasing the overall waste output from dairy farms.

The amount of land required for raising cows will decrease. With increased milk production efficiency, fewer cows may be needed to achieve the same milk output, thus reducing the overall land usage for dairy farming.

Cows and Carbon Dioxide: Livestock production, including dairy farming, contributes to greenhouse gas emissions. By using biotechnology to improve milk production efficiency and reduce the number of cows needed, there could be a potential decrease in the environmental impact relating to carbon footprint.
