Its not a case of the more the better. Its kinda like water....plants need water in the right amount but too much will drown them....unless of course they are underwater plants. (I just wanted to add that before one of the skeptics pointed it out). Haha
Our bodies expell co2 and too much in the human body will kill you.
Here's a little info on co2 for you...all the skeptics out there who don't understand or want to understand the greenhouse effect should study it a little because thats what the problem is all about...thats what causing our temperatures to rise and thats what gonna cost us a bundle to control.
Too much carbon dioxide and too few trees
by Steven Strauss
Nature provides its own greenhouse effect, which makes life on planet earth possible. But human activity is intensifying that effect dangerously.
Carbon dioxide in the atmosphere permits the heat rays of the sun to pass through it as the rays approach the earth’s surface, but does not permit the reverse passage as the rays are reflected back. The heat thus becomes trapped.
As more carbon dioxide fills the atmosphere, more heat is trapped. The temperatures of oceans, land masses, and ice caps rise. Warmer oceans evaporate more water into the air, leading to more powerful storms.
Warmer land masses breed more insects, leading to an increase in mosquito-borne diseases, such as malaria, dengue fever, and West Nile virus. Warmer ice caps break apart, destroying traditional fishing sites and livelihoods and threatening the survival of polar life.
Three-fourths of greenhouse CO2 comes from the industrial and automobile consumption of oil and coal.
But nature also has a built-in protector against a too-strong greenhouse effect: plant life is a natural sponge for atmospheric carbon dioxide. In the process of photosynthesis, trees take in CO2 and give off oxygen. Yet forests are being cleared around the world at the rate of one acre per second. Deforestation accounts for about 25 percent of the greenhouse CO2.
The leading perpetrators are the giant timber and beef industries. The latter is responsible for most of the Amazon deforestation, as land is cleared for cattle ranching. In 2004 alone, more than 10,000 square miles of the Amazon were cleared.
Climatologists estimate that since the start of the industrial revolution the earth’s average temperature has risen about 3.6 degrees Fahrenheit. The United Nations Intergovernmental Panel on Climate Change has projected a 10.4-degree spike by the year 2100, an assessment regarded as far too conservative by many scientists.
Climatology models predict that a 1.8-degree rise in temperature could lower corn, rice, and wheat yields by 10 percent.
Thus, a relatively recent quantitative increase in the atmospheric tonnage of CO2 has led to a qualitative change in the overall life of the planet.
This is a dramatic negative demonstration of the power of the economic productive forces that have evolved in human society.

I will add that its estimated about 90 million tons of greenhouse gas (most of which is co2) is dumped into out atmosphere each day by the burning of fossil fuels for energy.
Anybody who thinks this is OK.....please raise your hand.
