Carbon Dioxide

Carbon Dioxide:

 (CO2) A colorless, odorless gas that makes up the fourth most-abundant gas in the atmosphere, used by plants in carbon fixation. Atmospheric CO2 has increased about 25 percent since the early
1800s due to burning of fossil fuels and deforestation.Increased amounts of CO2 in the atmosphere enhance the greenhouse effect by blocking heat from escaping into space, thus contributing to the warming of Earth’s lower atmosphere and having an effect on the world’s biota. This is a major issue currently being debated by
scientists around the world.
