Which of the following approaches would be the most effective way to reduce greenhouse carbon dioxide?

a. Increase waste deposition into the deep ocean.

b. Plant more environmentally-suitable plants.

c. Increase use of fuel sources that do not produce carbon dioxide as a by-product.

d. Decrease livestock agriculture

Greenhouse gases include carbon dioxide, methane, nitrous oxide and other gases that accumulate in the atmosphere and create the heat-reflective layer that keeps the Earth at a livable temperature. These gases form the insulation that keeps the planet warm enough to support life.

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.

b. Plant more environmentally-suitable plants.

• Planting new trees is one of the most effective ways to reduce atmospheric carbon dioxide (CO2) and limit global warming. As forests grow they remove CO2 from the air through photosynthesis, working as a natural reservoir to store carbon.
• The most effective way to reduce greenhouse carbon dioxide is to Plant more environmentally-suitable plants.

a. Increase waste deposition into the deep ocean.

• The most effective way to reduce greenhouse carbon dioxide is to Plant more environmentally-suitable plants. Not by Increase waste deposition into the deep ocean. Hence this option is not correct.

c. Increase use of fuel sources that do not produce carbon dioxide as a by-product.

• The most effective way to reduce greenhouse carbon dioxide is to Plant more environmentally-suitable plants. Not by Increase use of fuel sources that do not produce carbon dioxide as a by-product. Hence this option is not correct.

d. Decrease livestock agriculture

• The most effective way to reduce greenhouse carbon dioxide is to Plant more environmentally-suitable plants. Hence this option is not correct.
