Question

when a commercial landfill becomes full, what happens next, according to environmental laws?
a plastic cover, dirt, and grass seeds are added.
it is left open so the smell can permeate the area.
it is watered heavily to increase chemical runoff.
all of the trash in the entire landfill is burned.

Explanation:

When a commercial landfill is full, environmental laws require proper closure. Adding a plastic cover, dirt, and grass seeds helps prevent pollution (e.g., leachate) and stabilize the site. Leaving it open (causes odor and pollution), heavy watering (increases harmful runoff), or burning (releases toxins) are all environmentally - harmful and not in line with regulations.

Answer:

A. A plastic cover, dirt, and grass seeds are added.
