Global climate change: greenhouse gases, water vapour, nitrous oxide, methane, chlorofluorocarbons, carbon dioxide. Without these gases the earth would freeze but too much pollutes the air. Severe weather patterns: weather will increasingly become unpredictable and more extreme and destructive events, loss of agricultural lands, extinction of plant and animal species, altered patterns of infectious disease, air pollution. Acceleration of evolution of hundreds of bacteria and viruses: many of these have occurred within a single generation within your lifetime, antibiotics, new diseases hiv, dengue hemorrhagic fever, legionnaires disease, lyme disease, tb, Resistant staphylococcus, e coli increased mortality due to infectious disease: overuse of pesticides and insecticides in agriculture. Solutions: culture has become the unintentional transformer of the environment, fuel efficient technologies, reduce population growth, environmental conservation, reducing global poverty.
