Answer: D

Explanation: Carbon sequestration may be carried out by pumping carbon into ‘carbon sinks’— an area that absorbs carbon.

  • Natural sinks – Oceans, forests, soil etc.
  • Artificial sinks – Depleted oil reserves, un-mineable mines, etc.

Carbon capture has actually been in use for years. The oil and gas industries have used carbon capture for decades as a way to enhance oil and gas recovery. Only recently have we started thinking about capturing carbon for environmental reasons.
