Question

human activities and climate change quick check
which human action would help reduce global warming? (1 point)
○ clear more forests to produce more farmland.
○ use more fertilizers to increase crop production.
○ eat less red meat so fewer cattle need to be raised.
○ ride a bicycle rather than walk to school.

Explanation:

• Clearing forests (first option) increases CO₂ as trees absorb it, worsening warming.
• More fertilizers (second option) can cause pollution and don't reduce warming.
• Eating less red meat (third option) reduces cattle farming; cattle produce methane (a greenhouse gas), so fewer cattle mean less methane, helping reduce warming.
• Riding a bike instead of walking (fourth option) is illogical as walking has no emissions, and biking also has low emissions, but this action doesn't help reduce warming compared to the relevant impact of reducing cattle - related methane.

Answer:

C. Eat less red meat so fewer cattle need to be raised.
