What would happen to co2 if there was less plants

More carbon dioxide (CO2) would be in our atmosphere.

Explanation:

Plants undergoing photosynthesis take in carbon dioxide (CO2) and give out oxygen (O2). They essentially use the CO2 to make sugars that keep them alive. Excess plant CO2 is then given off back into the environment, just like how we exhale CO2 after taking a breath.

So, no plants to take in the CO2 equals more CO2 in the environment.

Think of it kinda like this: I like Pop Tarts. If there is less or none of me in the world, there are more Pop Tarts just... out there... waiting to be eaten.
