Atmosphere: co2 (30% increase since the industrial revolution), cfc, Sulfur and nitrogen (acid rain), methane (60% increase) Biological (bacteria, viruses, parasites, allergens, animals such as bees and poisonous snakes (more freshwater is used) Geosphere (geo=land): 1/3 to 1/2 of the land surface has been transformed by human action mostly through mining. Biosphere (bio=life): of the bird population is now extinct (same goes to amphibians) mostly d/t cutting and clearing forests. Physical (radiation, fire, tornado, hurricane, volcanic eruption, earthquake) Social - (unsafe working conditions, poor diet, drugs, drinking, driving, poverty, smoking) - (housing, urban development, land use, transportation) Industrialization greater than population growth d/t fossil fuels, automobile industry, synthetic materials higher population = more need for materials and production. Industrialization and population (overpopulation and overconsumption) determines environmental transformation main driving forces of environmental degradation.
