Also I hate when people say that switching to some more efficient thing takes X number of cars off the road. what about shutting down X coal plants or X trains or X amount of cows farting?

I know moderation is the key. However Co2 above certain levels, just 5% by volume, is toxic. Are we anywhere near that(varies from .03-.06% depending on location)? hell no. Co2 levels were considerably higher 500 million years ago... I'm just bored at work and im splitting hairs

Just doesnt support life? sounds toxic to me!
According to the Australian Maritime Safety Authority, "Prolonged exposure to moderate concentrations can cause acidosis and adverse effects on calcium phosphorus metabolism resulting in increased calcium deposits in soft tissue. Carbon dioxide is toxic to the heart and causes diminished contractile force. At concentrations of three per cent by volume in air, it is mildly narcotic and causes increased blood pressure and pulse rate, and causes reduced hearing. At concentrations of about five per cent by volume it causes stimulation of the respiratory centre, dizziness, confusion and difficulty in breathing accompanied by headache and shortness of breath. At about eight per cent concentration it causes headache, sweating, dim vision, tremor and loss of consciousness after exposure for between five and ten minutes."
Also Co2 is used in gas chambers as well. its a toxic gas. Once again im just splitting hairs cause im bored.
