If I ever take up an interest in science, I might look into climate change and find out some facts! Good idea!

And I know, Peter and his videos are so annoying but I just can’t look away. Know what I mean?

He is a science propagandist who uses discredited facts, such as, “CO2 created the ice ages,” to promote belief that consensus science is already proven. Besides, they’re all annoying. You should take the time to research the facts yourself.

Even non-limiting nutrients of our diet are food. Is there some other term we should be using?

The video does a good job showing that higher levels of CO2 are damaging, but it doesn’t refute the idea of it being food for plants.

Another question: Is air a food for humans?

Fine print at the bottom, 8pt Italic French Cursive: “…in those circumstances where CO2 is the limiting factor to plant growth.”
