What is considered a carbo sink?

A carbon sink is a natural or artificial system that absorbs more carbon dioxide (CO2) from the atmosphere than it releases, effectively reducing the concentration of CO2 in the air. Examples of carbon sinks include forests, oceans, and soil, where plants and other organisms capture CO2 during photosynthesis and store it as biomass or organic matter. These systems play a crucial role in mitigating climate change by offsetting greenhouse gas emissions.
