question 6 of 20
lawmakers discuss methods of preventing pollutants that could directly start a positive feedback loop in the area shown in the picture.
which of these actions should they take?
a. lower allowed concentrations of particulate matter released from factory smokestacks.
b. increase the number of jets flying in the upper troposphere.
c. ban the composting of food waste.
d. increase funding for coal technology.

Explanation:

Lowering particulate - matter emissions from factory smokestacks reduces pollutants that can cause environmental problems and potentially start positive - feedback loops. Increasing jet flights can release pollutants and contribute to climate change. Banning food - waste composting is counter - productive as composting is beneficial for soil health and reduces waste in landfills. Increasing coal - technology funding would likely lead to more coal use and higher pollutant emissions.

Answer:

A. Lower allowed concentrations of particulate matter released from factory smokestacks.
