Which of the following negative impacts on the environment are a result of waste being transported/diverted to landfills?
A . Increased pre-consumer recycled content
B . Decreased post-consumer recycled content
C . Waste is incinerated and used to generate energy
D . Solid waste produces methane and potent greenhouse gas

Answer: C

Explanation:

Waste that is transported or diverted to landfills can have negative impacts on the environment, such as occupying valuable land, contaminating soil and water, and emitting harmful gases. One of the most significant impacts is the production of methane, a potent greenhouse gas that contributes to global warming and climate change. Methane is generated when organic waste decomposes anaerobically (without oxygen) in landfills. Methane has a global warming potential 28 times higher than carbon dioxide over a 100-year period12.
