Carbon Dioxide is plant food.
They take it in and release oxygen in return.

Those of us who stayed awake in second grade science class already know this. Apparently the global warming crowd does not.

It’s nature’s answer to recycling. Any other viewpoint is just plain dumb.

Try this on for size...

- Animal life on Earth take in Oxygen and expel CO2.
- Plant life on Earth take in CO2 and expel Oxygen.
- Human life on Earth has been growing in population and expelling more CO2 through increased respiration and the oxidation of fuel sources to stay alive.
- Plant life on Earth is expanding (greening) due to an increase in CO2 to use for transpiration.

Cause and effect?

So, Carbon Dioxide is LIFE?
