 * What are the 8 categories of 'classical' ecological damage? What are the 4 new ones?**

The categories for classical ecological damage include: There are also four new categories of ecological damage, including:
 * 1) Deforestation and habitat destruction (e.g. Greenland story from the Tale of Two Farms);
 * 2) Soil problems (usually, deforestation causes soil erosion due to lack of support, leading to the loss of fertility and desertification);
 * 3) Water management problems;
 * 4) Overhunting (mass hunting for fur, ivory and bones will quickly lead to the endangerment and extinction of species);
 * 5) Overfishing (e.g. large netting boats);
 * 6) Effects of introduced species on native ones;
 * 7) Human population growth (crowding and overpopulation in third-world countries causes rapid resource depletion); and
 * 8) Increased per capita impact of humans.
 * 1) Buildup of toxic chemicals and pollution (e.g. illegally or improperly discharging chemicals);
 * 2) Climate change (e.g. global warming due to excess of greenhouse gases);
 * 3) Energy shortages (i.e. overdependency on nonrenewable resources causing a threat to energy supply); and
 * 4) Full utilization of earth's photosynthetic capacity. (read as: reaching the point where we are using all the energy the earth can produce)
