Question

Which human action would help reduce global warming
Right bicycle rather than walk to school
Use more fertilizer to increase crop production
Clear more forest to produce more farmland
Eat less red meat, so pure cattle need to be raised

Answer 1

The action that would help reduce global warming is to **eat less red meat, so fewer cattle need to be raised**.

Livestock production, particularly cattle, contributes significantly to greenhouse gas emissions, including methane, which is a potent greenhouse gas. Reducing the demand for red meat can lead to lower cattle production, helping to decrease these emissions.

In contrast:

- Riding a bicycle rather than walking to school is a good practice for reducing carbon footprint, but it doesn't directly relate to reducing global warming on a larger scale as much as dietary changes would.
- Using more fertilizer can lead to increased emissions of nitrous oxide, another potent greenhouse gas.
- Clearing more forest for farmland contributes to deforestation, which releases stored carbon dioxide and reduces the planet's capacity to absorb CO2, thus exacerbating global warming.

Overall, dietary choices, particularly reducing red meat consumption, have a more significant impact on climate change mitigation.
