"the idea that carbon dioxide is a carcinogen that is harmful to our environment is almost comical. Every time we exhale, we exhale carbon dioxide."... - House Minority Leader John Boehner
HAASE Comment: Not so funny that we have thousands of people who die every day due to hazardous air and water conditions in our world produced by toxic chemicals. CO2 is not that... and while it may be the byproduct of a problem, it is not the 'root' or the 'cause'.

'Carbon dioxide is used by plants during photosynthesis to make sugars which may either be consumed again in respiration or used as the raw material to produce polysaccharides such as starch and cellulose, proteins and the wide variety of other organic compounds required for plant growth and development. It is produced during respiration by plants, and by all animals, fungi and microorganisms that depend on living and decaying plants for food, either directly or indirectly. It is, therefore, a major component of the carbon cycle.'
