D Correct answer
Explanation

Expanding agricultural land and increasing water withdrawals are not strategies for promoting water conservation in agriculture. Instead, water conservation in agriculture focuses on optimizing water use and reducing water losses.

Multiple choice

The documentary 'Cowspiracy' focuses on the environmental impact of animal agriculture. Which of the following is NOT a key argument presented in the film?

  1. Animal agriculture is a major contributor to greenhouse gas emissions.

  2. Animal agriculture is a leading cause of water pollution.

  3. Animal agriculture is responsible for a significant portion of deforestation.

  4. Animal agriculture is a sustainable and environmentally friendly practice.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

'Cowspiracy' argues that animal agriculture is a major contributor to environmental problems, including greenhouse gas emissions, water pollution, and deforestation. It does not present the argument that animal agriculture is a sustainable and environmentally friendly practice.

Multiple choice

A farmer is considering two different crop rotation systems, A and B. System A has a 10% chance of resulting in a yield loss of 20%, a 30% chance of resulting in a yield increase of 10%, and a 60% chance of resulting in no change in yield. System B has a 20% chance of resulting in a yield loss of 30%, a 40% chance of resulting in a yield increase of 20%, and a 40% chance of resulting in no change in yield. Which system has the lower risk of yield loss?

  1. System A

  2. System B

  3. Both systems have the same risk of yield loss

  4. Cannot be determined from the given information
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The risk of yield loss is measured by the expected value of the yield loss distribution. The expected yield loss for System A is (0.1 * -0.2) + (0.3 * 0.1) + (0.6 * 0) = -0.02. The expected yield loss for System B is (0.2 * -0.3) + (0.4 * 0.2) + (0.4 * 0) = -0.06. Therefore, System A has the lower risk of yield loss.

Multiple choice

  4. By reducing the need for chemical fertilizers
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Wind turbines can help to reduce greenhouse gas emissions in agriculture by reducing the need for fossil fuels to power farm equipment and irrigation systems.

Multiple choice

How can wind energy help to reduce the need for chemical fungicides in agriculture?

  1. By providing a source of nitrogen

  2. By reducing soil erosion

  3. By increasing soil moisture

  4. By improving soil quality
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Wind turbines can help to reduce the need for chemical fungicides in agriculture by improving soil quality and reducing the incidence of fungal diseases.
