Answer:
Humans can reduce their greenhouse gas emissions (typically carbon, methane, etc.) by switching to all-electric appliances (a good brand that services this is Energy Star), using clean, renewable resources such as wind, solar, hydro, and thermal energy, and switching from a gas-powered car to electric, a huge step to reducing greenhouse gas emissions.
Step-by-step explanation:
Greenhouse gases are gases that get trapped in the atmosphere and tend to produce more heat on Earth, the way a greenhouse traps heat for the purpose of growing plants better. However, greenhouse gases are bad for our atmosphere, and doing the things listed above can help improve our atmosphere. Hope this helps :)
