Why is food for vegetation (CO2) considered pollution while bread is not considered poison?

Maybe we should make a list of all the 100% safe chemicals first.

Let's work through the atmosphere:

1. Nitrogen - Not safe. If your room was 100% nitrogen you would die.

2. Oxygen - Not safe. If your room was 100% oxygen you would feel quite strange. It would force you to give up smoking, though! So perhaps it is not all bad.

3. Argon - Not safe, again you would die in an argon-filled room.

4. Water - Not safe. Drowning would occur.

5. Carbon Dioxide - Not safe.

6. Neon - Not safe. If you had a battery with a high enough voltage you would not need any light bulbs.

In fact, I can't think of a safe chemical in the atmosphere.

The EPA could have picked on any chemical to demonise. The big money didn't like CO2 so the picked that.

I don't consider CO2 pollution, But there is a natural balance of CO2 in the environment and upsetting that balance is bad. So the words people use are just inadequate to describe the concepts being discussed.

CO2 shouldn't be considered a poison anymore than water but when you have wacko leftists that have an industry and an economy to destroy then it is useful to call CO2 pollution. I have a pretty severe wheat allergy so for me it is pretty toxic and it is everywhere and in just about everything it seems.

My doctor never told me I was allergic to gluten but that may very well be. She just said "wheat" and on my test where they stick your arm with all sorts of potential substances that might cause allergies, wheat was equal to histamine (Nurse said she never saw that before) and forced her to give me Benodril. I've gone to the emergency room twice for wheat related allergies (anaphalactic shock). Both times I lost consciousness. The last time was after my wife's wonton soup so I sometimes tell the story where her cooking put me in the emergency room. Luckily she has a good sense of humor about it. No more wheat for moi.

Bread could be considered poison for some, especially say diabetics. The other answer is the greenhouse effect.

Who says CO2 is a "poison"?

Science haters?

In very small amounts, cyanide is a nutrient, in larger amounts it is deadly.

CO2 is the same, in that respect.

But if you hate science, and are incapable of understanding some other deception about it, why post fake questions here? Why not instead learn how to deceive more persuasively?

too much C02 traps heat and makes the oceans acidic

and bread is 'poisonous' to people with gluten allergies

pollution is anything in excess

you're such an idiot you can't understand

Plants also need water, do you think most of them would do better if their fields were flooded?

I really don't understand why you even believe your question makes sense.

no i fell
