Answer and Explanation:
The idea of potentially reusing or recycling CO2 has received less attention. However, science has long recognized that it is possible to recombine carbon from CO2 with hydrogen from water to produce hydrocarbons, or familiar fuels like gasoline.
Carbon Recycling in Context
When animals eat plants or eat other animals that have eaten plants, they ingest carbon. Photosynthesis produces oxygen as a byproduct, which is fortunate for us! Plants and animals decompose and return carbon to the soil when they die.
