There are loads of substances that are “essential elements of life” in some contexts and pollutants or health threats in others. Hydrogen, carbon and oxygen are three of these. Try rolling in benzene some time and see how that works for you. What is benzene made of? Try breathing in some O3 and see how your lungs do; yet, it protects us in certain conditions from tumors. For that matter, try putting yourself in a room filled with carbon dioxide and see how that essential element of life treats you. Even arsenic has its uses in certain amounts and for certain ends. Our reaction to elements and molecules and substances is conditional. Allow yourself to think conditionally.

Greenman, 33.3. percent is a big change, in percentage terms. In molecular terms, it’s still 1 in 10,000. Nice try. T Lu is also correct about historic CO2 levels – before humans ever started burning fossil fuels – and the fact that you have been living off the energy from the earth’s productivity during that time.

Jim, arsenic is a known pollutant. It is not an essential element of life, like carbon, hydrogen, and oxygen. You are comparing apples to orangutans (not even oranges).

To both, know how much of the tax raised from cap and trade is going to “alternative energy R&D”? About 23%. Know where the balance is going? A) to +/- 40 new federal dept./agencies to administer CO2 programs/cap & rape, and B) Obama’s “wealth redistribution” (aka middle class tax cuts). This isn’t about the environment. Green jobs? At least one and as many as 4 “dirty” jobs will be eliminated for each “green” job created.

These figures are easily checked, but your mindset doesn’t want to know facts, especially if it stands in the way of your “green agenda”.

In short, CO2 isn’t a “pollutant” except in politics, and this is about wealth redistribution. You are eco-socialist who know NOTHING about atmospheric science and related cost/benefit analysis. You are simply watermelons: green on the outside and red on the inside.

Hope you have the balls to allow this post.

t lu, look at things in perspective – what you’re talking about is a dramatic shift. From 3 parts per 10,000 to 4 parts to 10,000 is an increase of 33.3 percent. That’s a big change.

Do you know what a small amount of arsenic in your blood is required to kill you? Would you argue that that small level means that the arsenic doesn’t matter? Get real – one drop of mercury in your morning coffee would drop you flat, but are you going to say that you don’t need to worry about it, because it’s just a drop?

blah, blah, blah, blah, blah, blah.

And if you complain that I’m making fun of you, you’re a NAZI — just like that Luftwaffe goon Al Gore.
