do we humans pollute...yes
do we humans waste...yes
do we humans overdevelop and cut trees(a natural radiant cooler and co2 user/o2 PRODUCER)...yes
do we humans the add to ENVIROMENTAL CHANGES.........YES and NO
are we humans the cause of the earths CLIMATE changes........NO
the problem here is that people are using BAD FALSEIFIED SCIENCE to scare people about warming or cooling and they are using c02 as a scapegoat
everyone knows (and its scientifically proven) that climate has changed many, many times
and yet NOT ONE scientist has proven MANMADE global warming
the globe evolves. The global environment changes..periodically...there have been WARMER TIMES..there have been cooler times..there have been times when C02 was MUCH, MUCH higher
guess what our co2 levels are currently around 350ppm
co2 levels were over 700 ppm 20 thousand years ago....so what's the big deal
guess what, by science no less...the ideal co2 ppm for most plants is....700-1500 ppm
The air's CO2 content rises, most plants exhibit increased rates of net photosynthesis and biomass production. Moreover, on a per-unit-leaf-area basis, plants exposed to elevated CO2 concentrations are likely to lose less water via transpiration, as they tend to display lower stomatal conductances. Hence, the amount of carbon gained per unit of water lost per unit leaf area - or water-use efficiency - should increase dramatically as the air's CO2 content rises. In the study of Serraj et al. (1999), soybeans grown at 700 ppm CO2 displayed 10 to 25% reductions in total water loss while simultaneously exhibiting increases in dry weight of as much as 33%. Thus, elevated CO2 significantly increased the water-use efficiencies of the studied plants.
In summary, it is clear that as the CO2 content of the air continues to rise, nearly all of earth's agricultural species will respond favorably by exhibiting increases in water-use efficiency. It is thus likely that food and fiber production will increase on a worldwide basis, even in areas where productivity is severely restricted due to limited availability of soil moisture. Therefore, one can expect global agricultural productivity to rise in tandem with future increases in the atmosphere's CO2 concentration.
so more co2 is actually GREENER...its not theory, its scientific fact
science shows that humans use oxygen and expel (exhale) co2
science shows that greenery (plantlife) uses co2 and expels o2
science shows that co2 levels have been 3 times HIGHER than they are today, in the past (ie the co2 325 of today is is much lower than the 750-800 that co2 levels were 100,000 years ago
science shows us that the earth has warmed AND cooled many times
science shows us that ANTARTICA was once a lush fertile land, not covered in ice
science shows us that Greenland was once a green lush fertile land, not covered with ice
science shows us that GLACIERS created many of the geographical features that we look at today (ie Long Island was made by the lower reaching of glaciers, the great lakes were created by glaciers, the grand canyon was created by glacial melting)
science shows us that plants would grow much better, and use less water if the co2 was HIGHER
The typical outdoor air we breathe contains 0.03 - 0.045% (300 - 450 ppm) CO2. Research (SCIENCE) demonstrates that optimum growth and production for most plants occur between 1200 - 1500 ppm CO2. These optimum CO2 levels can boost plant metabolism, growth and yield by 25 - 60%.Plants under effective CO2 enrichment and management display thicker, lush green leaves, an abundance of fragrant fruit and flowers, and stronger, more vigorous roots. CO2 enriched plants grow rapidly and must also be supplied with the other five "essential elements" to ensure proper development and a plentiful harvest.
common sense states that as the earths population expands, so does the need for more plantlife...to keep our oxygen levels up.......yet the global warming liberals only want to talk about car/industry exhaust; man created co2,.... and how to tax it
