Plants and Ecology

Reagan had what we call a mysterious mind, on the other hand, Bush just has a mystery for a mind. The mind of the american electorate is the biggest mystery of all.
Vote early, vote often, vote Kucinich.

Both Reagan and Bush must haved learned about science from reading the same comic books. I think I'll let someone like Farmerman come to the rescue of this thread.

Idiots!

Re: Plants and Ecology


To tell you the truth, 80 percent of air pollution stem from man-made sources- not just vehicles and industries but also from Carbon dioxide that we expire.

Plants do release respiration products like CO2 when they arent photosynthesizing. Conifers give off volatile organic compounds. I have no ide about the percentages, and thats immaterial anyway. We can control our emmissions .

Plants use more CO2 for photosynthesis that they give off in respiration. The balance is in the plant body itself. When the plant dies the CO2 is either eaten, and the CO2 returns to the atmosphere, or else becomes humus or peat or coal, eventually. I think the point is that before technology, the CO2 level in the atmosphere would vary somewhat but become stabilized by the increase or decrease of plant ranges and growing seasons determined by the warming or cooling climate. But the rapid increase of CO2 put into the air by the rapid buring of fossil fuels is way beyond the capability of plants to stabilize, especially when considering the rapid loss of forests.
