Document Summary

Need to mine it, transport, process, and power plant, leading to waste disposal. Only solar and wind plants have power plant. Power plant emissions - hard coal vs gas (coal is bad) Energy payback: wind(23)>nuclear(16)>coal(11)>solar(6) solar is now about 23 (same as wind) Annual land use: nuclear is smallest, wind and solar is highest. Large particles vs small particles our lungs can catch the large particles but not the small ones. Ozone, noxs, hoxs, co, heavy metal usage. Synergism: 2 or more chemicals react asthma. Inability to measure levels of chemicals such as estrogen and testosterone steroids. Inability to understand how a chemical is modified in a complex environment. Some chemicals can impact ecosystems in unintended ways. Most biologically active chemicals exist in isometric forms. Thalidomide has adverse effects on child development in pregnant woman: probably affected abortion. Find out how we release chemicals and how they impact earth. With this, we can act on shit.
