“Even more striking is the fact that the con - centrations of free oxygen and carbon dioxide that exist today in the atmosphere of the earth differ profoundly from those that prevailed before the appearance of life.”
“This list includes, among many other things, baking soda and vinegar, which together produce carbon dioxide gas, and diluted hydrochloric acid mixed up with sodium sulfide, which makes a stinkazoid rottenegg smell in no time.”
“It enters the food web via photosynthesis, which is the process whereby green plants take in carbon dioxide molecules from the atmosphere and use energy from sunlight to combine the carbon atoms with water to make sugars.”
“Several hoses did reach through the air lock, but their inner ends entered tanks in which pseudolife forms precipitated carbon dioxide as calcium carbonate — they simply provided fertilizer for the oxygenmakers.”
“The carbon dioxide will be absorbed but not the nitrogen, so there will be a buildup in the counterlung that you'll need to vent.”
“And likewise, a ton avoided has the same impact whether it is from: reduced energy use; carbon capture and storage; renewable energy; or from trapping carbon dioxide in vegetation - in other words, growing trees.”
“Meanwhile, burning coal constitutes the largest human-generated contribution to atmospheric carbon dioxide and is a major source of methane; both gases are proven causes of climate change and global warming.”
“There are tiny nematode worms (related to the elegant Caenorhabditis) which live inside leaves (as many as 10,000 of them in a single badly infected leaf), diving into them through the stomata, which are the microscopic holes through which leaves take in carbon dioxide and release oxygen.”
“We have a scrubbing machine that absorbs the breathed-out carbon dioxide from the atmosphere and pumps it out into the sea.”
“We need to act now and make the United States a leader in puting in place the standards and incentives that will ensure that these plants use available technology to capture carbon dioxide and dispose of it safely underground.”
