VOICED: Scientists in N.Zealand try to tackle cow

The video discusses the environmental impact of livestock, particularly cows and sheep, on greenhouse gas emissions. It highlights research efforts to measure and reduce methane and nitrous oxide emissions through various methods, including dietary changes and technological innovations. The video also addresses the challenges farmers face in adopting these practices, such as economic concerns and the unpopularity of carbon taxes.

What percentage of the world's greenhouse gas emissions is attributed to livestock, according to the United Nations?

• 10%

• 18%

• 25%

• 35%

In New Zealand, what is the approximate number of cows contributing to more than half of the country's greenhouse gas emissions?

• 10 million

• 12 million

• 8 million

• 5 million

What is one method used by scientists to study methane emissions from livestock?

• Collecting soil samples

• Using an intricate tubing system

• Installing GPS trackers on animals

• Using drones to monitor emissions

What is the global warming potential of nitrous oxide compared to carbon dioxide?

• 310 times more

• 200 times more

• 500 times more

• 100 times more

Why might farmers be hesitant to adopt new practices for reducing emissions?

• Insufficient government support

• High costs without immediate benefits
