Why Do Forests Absorb More CO2 Than They Release?

Imagine forests as giant sponges that drink up CO2 like a thirsty kid drinks lemonade. During the day, trees use sunlight to eat CO2 and grow, this is called photosynthesis. But at night, they breathe out some of it, just like humans do. However, because they are busy eating CO2 during the day more than they breathe it out at night, forests end up absorbing more CO2 overall.
