Wrongfully. So fascists can implement a carbon credit scheme.
My fist is toxic if I jam it down your throat and rip out your lungs. let's not sculpt boutique situations to justify moronic policy, ok, shnookums.
Nah, your fist would only be a minor annoyance.
But since you seem woefully under educated on the science we are discussing, let me see if I can help you.
How about we start with the definition of "pollutant".
From the American Heritage Science Dictionary:
"A substance or condition that contaminates air, water, or soil. Pollutants can be artificial substances, such as pesticides and PCBs, or naturally occurring substances, such as oil or carbon dioxide, that occur in harmful concentrations in a given environment. Heat transmitted to natural waterways through warm-water discharge from power plants and uncontained radioactivity from nuclear wastes are also considered pollutants."
You are operating under the misconception that pollution ONLY involves chemicals that are dangerous at any concentration.
While that may make you feel better, it isn't the scientific definition.
Any substance that contaminates the air, water, or soil. A significant increase in CO2 fits that definition.
But let me allow you a chance to define it.
It is a scientific FACT that CO2 allows the energy from the sun to pass thru. It is a scientific FACT that CO2 does not allow the heat from the earth to escape.
It is a scientific FACT that a significant increase in CO2 in the atmosphere would, therefore, cause a net gain in the temperature of the planet.
So what term would YOU use to classify the gas that causes an increase in the temperature?
What term would YOU use to classify a gas that, in sufficient quantities, changes the heat exchange rate for the planet?
