List things that all humans need to survive.
What are some things we depend on to support a comfortable lifestyle in 2012?
What is the difference in “survival” and “lifestyle”?
List some things you enjoy but could survive without?
Home many things can be made from a tree?
Quick Review1. I provide clean energy from running water which turns giant turbines, but
there are fewer and fewer locations where I will work
2. I am the most abundant of fossil fuels, a nonrenewable source of energy, expensive to mine, and a cause of acid rain (pollution)
3. I am the “hope for the future.” A free and non-polluting source of energy but expensive to build in homes. On cloudy days I’m hard to find.
4. I release an enormous amount of energy but am dangerous due to high risks of radioactive waste products, meltdowns, and radiation exposure. I form from the splitting nucleus of uranium atoms.
5. I am the cleanest burning fossil fuel but will leave large craters in the earth from where I’m extracted and am highly flamable if handled carelessly.

Who am i?
Deforestation• Explanation:– Removal of trees so land can be used for other
purposes
Deforestation• How bad is it for the environment?– Responsible for ~ 20% of Earth’s greenhouse
gasses– less CO2 removed from atmosphere by trees– damages soil, increased erosion
Deforestation• Solution?– Replant trees and use other materials or energy
sources to prevent cutting down trees
Urbanization• Explanation:– Physical and massive growth of and migration to
large cities
Urbanization• How bad is it for the environment?– Heat is becoming more abundant & heat is
absorbed
Urbanization• Solution?– Implement places where land will not be harmed– Reclamation– Urban farming
Overgrazing• Explanation:– Plants are exposed to intensive grazing for long
periods of time without enough time to recover – caused by poor agricultural applications or overpopulations of invasive species
Overgrazing• How bad is it for the environment?– Increases soil erosion which harms future
agricultural productivity
Overgrazing• Solution?– Can be corrected with lime and organic fertilizers– Loss of soil depth, however, takes centuries to
correct
Agriculture• Explanation:– Also, FARMING– Cultivation of plants, animals, fungi and other life
forms for food, fiber, and other products used to sustain life

Agriculture• How bad is it for the environment?– We have to overuse farms in order to sustain a
growing human population. We use too many chemicals such as pesticides and fertilizers
Agriculture• Solution?– Population control– Sustainable farming– Practices (organic
