CLEAN: Scientists in N.Zealand try to tackle cow e

The video tutorial discusses various experimental conditions to measure methane emissions, such as using different animal feeds, vaccines, and inhibitors. It highlights the significant global warming potential of nitrous oxide, which is 310 times that of carbon dioxide, and the hesitance of farmers to adopt new practices without economic incentives like carbon taxes. The tutorial also covers techniques for measuring gas emissions, including the use of chambers and sampling methods.

Which of the following is NOT mentioned as a method to study methane emissions in animals?

• Changing the animal's diet

• Increasing the animal's exercise

• Using different animal species

• Administering a vaccine

How much more potent is nitrous oxide compared to carbon dioxide in terms of global warming potential?

• 310 times

• 200 times

• 400 times

• 100 times

What is a potential benefit of keeping nitrogen in plants?

• It decreases soil erosion

• It reduces water usage

• It increases crop diversity

• It promotes more grass growth

Why might farmers be hesitant to invest in methods to reduce nitrous oxide emissions?

• Limited market demand

• Complex technology requirements

• High labor costs

• Lack of evidence for effectiveness

What is the purpose of using a chamber in the context of the video?

• To store feed samples

• To measure gas emissions

• To control temperature

• To house animals for observation
