Great job! You got all the answers correct.
The human action that would help reduce global warming is:
- Eat less red meat so fewer cattle need to be raised.
- Ride a bicycle rather than walk to school.
Explanation: Eating less red meat reduces the demand for cattle, leading to a decrease in the number of cattle raised for meat production. This is beneficial because cattle produce methane, a potent greenhouse gas that contributes to global warming. By reducing the demand for red meat, we can decrease the number of cattle, which in turn reduces methane emissions.
Similarly, riding a bicycle instead of walking to school (when feasible) can reduce greenhouse gas emissions. This is because bicycles do not require fuel like cars or motorcycles, which emit carbon dioxide (CO2) during combustion. By choosing a non-motorized mode of transportation, we can reduce our carbon footprint, helping to mitigate global warming.
On the other hand, using more fertilizers to increase crop production and clearing more forests to produce farmland are not helpful actions to reduce global warming. Increased fertilizer use can result in the release of nitrous oxide (N2O), another potent greenhouse gas. Clearing forests also leads to the release of stored carbon, further contributing to greenhouse gas emissions. Both of these actions have negative environmental impacts and can exacerbate the problem of global warming.
