1. Additional atmospheric CO2 causes an astonishing increase in plant growth.
CO2 is the food that plants eat. Plants and trees have already experienced growth increases of about 12% and 18% respectively with just 105 parts per million (ppm) man-made increase. Look at Table 1 below to see the growth benefits proven by controlled studies of plants subjected to a 300 ppm increase in CO2 levels.
2. More atmospheric CO2 (300 ppm) will cause plants to need even LESS water.
Plants make morphological adjustments that result in their requiring less water while growing faster and more massive. The reduced water requirement can range up to 40%.
3. Certain health-promoting substances, such as vitamin C and antioxidants, are increased with additional airborne CO2.
These improvements are clearly in the direction of improving human health in that eating the identical volume of some fruits or vegetables will result in a greater consumption of vitamins, minerals and even some herbal nutrients.
4. With much more food production per acre, Earth should be able to feed an expanding population and save habitats and ecosystems.
Academic studies have shown that to feed the expected nine billion population in 2050, we will need to convert all remaining arable land to farmland. While Earth's CO2 levels will probably not rise by 300 ppm by 2050, the increased levels, whatever they are, should certainly help feed the expanding population and save many millions of acres of current habitats and ecosystems from conversion to farmlands, which are the greatest destroyer of wildlife habitats.
5. Existing habitats and ecosystems will have a higher plant and wildlife capacity.
The plants and forest environments will provide more food and shelter as CO2 enrichment causes more plant, food and forest growth.
6. The greening of Earth will continue and extend into the deserts as plants become more tolerant of drought.
Repeat photos of desert environments taken approximately 100 years apart help illustrate the significant growth enhancement we expect the approximately 70 ppm rise in CO2 to have provided over that period. Imagine what an additional 300 ppm CO2 enrichment can do for greening Mother Earth (see photos below).
7. Plants become more resistant to various stresses when grown in an enriched CO2 atmosphere.
Plants become more resistant to many stresses when grown in an atmosphere of elevated CO2. Some of these stresses include plant diseases, insect infestations, climate changes (hotter or colder), nutrient depletion, salinization, less water, and air pollution.
8. Dramatic increases in the growth rates of Earth's forests will speed the recovery from recurring natural disasters and aid a renewable resource industry.
As seen in Table 1, trees generally respond even more dramatically than plants to increased levels of CO2.
This should help forests recover from natural disasters more quickly and reestablish habitats and prevent top soil erosion. Renewable resource industries such as lumbering and pulp wood product providers will be aided and not have to expand their operations into untouched forests in order to keep up with the demands of a growing population
9. CO2 is Earth's greatest airborne fertilizer.
In addition to being what plants eat, CO2, unlike other fertilizers such as nitrogen and phosphorous, is distributed worldwide in days or weeks by simply being emitted into the atmosphere. It begins dispersing immediately and continues 24/7 until it has surrounded the Earth and fertilized all the plants.
10. CO2 is the staff of life for Earth's plant kingdom, which is the beginning of the planet's food chain; without CO2 there would be no life on Earth.
CO2 is what plants eat and causes them to grow and produce food. A byproduct of plant photosynthesis is oxygen which is also critical to many living organisms. We breathe in oxygen and CO2 with no ill effects. CO2 helps keep the Earth warm, particularly in its first 100 ppm concentration in the atmosphere. Today, at 400 ppm, and rising, CO2 is having a miniscule effect on Earth's temperature change (see figure below).
