Kidneys compensate for acid-base imbalances by : Reabsorbing HCO₃ from urine back to the blood and also secreting H⁺ back to the urine.
<h3>Acid-base Imbalance </h3>
When the amount of acid or base produced in the human body is greater than or less than the required amount of acid or base, and the rate of excretion by the kidneys is above or below normal, the body will experience an Acid-base imbalance situation.
To correct acid-base imbalance in the body the kidney will reabsorb HCO₃ form the urine and while secreting Hydrogen ions back to the urine.
Hence we can conclude that Kidneys compensate for acid-base imbalances by : Reabsorbing HCO₃ from urine back to the blood and also secreting H⁺ back to the urine.

Basically everything would die off. All plants take in CO2 from the atmosphere, which is then used in photosynthesis creating glucose and oxygen. Oxygen is a definite need for us and then of course the plants are eaten and the glucose/carbon cycles through the food chain.
Since there isn't an unlimited amount of carbon available to us, we need the carbon cycle to replenish the stores.
