Question

Which three methods are valid for preventing further environmental damage from CO2?

Answer 1

Remove Excess CO2 via scrubbing
Replace energy from fossil fuels with geothermal solar energy.
Sequester released CO2 before it reaches earth's atmosphere

Answer 2

Three methods are valid for preventing further environmental damage from CO2:

A) Removing excessive $CO_2$  from the atmosphere through scrubbing.

B) sequester the released $CO_2$ before it reaches the atmosphere.

D) Replace energy obtained from fossil fuels with geothermal and solar energy.

Explanation:

Scrubbing is a process through which we can precipitate the $CO_2$, these are used in Industrial exhausts to limit the $CO_2$ release.

Sequestration is the storage of Industrial$CO_2$ produced by fossil fuels in an underground aquifer or any other structure for long term storage.

Solar and Geothermal energies are called as Green energy, as they do not release any green houses gases in production. They are renewable source of energies. Replacing them with fossil fuels reduces release of $CO_2$
