Match the human activity and how it increases the greenhouse affect
laiz [17]

Answer:

1. primary cause of human-created carbon emissions = burning fossil fuels

2. destroys natural carbon sinks leading to more carbon dioxide in the air = deforestation

3. emits methane from decomposing matter = waste disposal in landfills

Explanation:

1. "Fossil fuels" are <em>nonrenewable resources</em> that are considered essential for the operation of many factories and industries. <em>Burning them accounts for most of the carbon emissions on Earth</em>, and this leads to<em> "global warming."</em>

2. "Forests" are considered "carbon sinks" because they have a role of <u><em>absorbing the carbon dioxide in the atmosphere</em></u>. Cutting down the trees (deforestation) makes forests barren. It then leads to more carbon dioxide in the air.

3.<em> Waste disposals in landfills contribute to the amount of methane that is released into the atmosphere.</em> Methane is considered a <em><u>potent greenhouse gas</u></em> that affects people's health.
