Environment Problem

1. rely on Solar energy

   Anotações:

   • – Warms earth – Provides energy for plants to make food for other organisms – Powers winds – Powers the hydrologic cycle – which includes flowing water – Provides energy: wind and moving water can be turned into electricity
2. protect Biodiversity

   Anotações:

   • – Large variety of species – Many ecosystems • Deserts • Forests • Oceans • Grasslands – Species and systems renew soil and purify air and water.
3. NOT disturb Chemical Cycling

   Anotações:

   • –Natural processes recycle nutrients –Recycling is necessary because there is a fixed supply of these nutrients on earth –Nutrients cycle from living organisms to the nonliving environment and back –Chemical cycles are necessary to sustain life

1. services
   1. purification
   2. nutrient cycle

      Anotações:

      • From the environment to organisms and back to the environment
2. resources
   1. (non)renewable energy
      1. renewable

         Anotações:

         • –days to centuries –Water –Air –Grasslands –Forest –Soils –Fish populations
   2. based on human
   3. Perpetual

      Anotações:

      •  – renewed continuously – Solar energy
3. Photosysthesis

Anotações:

• – The amount of biologically productive land and water needed to indefinitely supply the people in a given area with renewable resources – Also includes the land and water necessary to absorb and recycle wastes and pollution

1. per capita ecological footprint(area)

   Anotações:

   • Average ecological footprint of an individual in a given area
2. Ecological deficit

   Anotações:

   • Total ecological footprint greater than biological capacity for resource renewal and absorption of wastes and pollution

1. Population
2. Affluence
3. Technology
4. I = P + A + T

1. 4R
   1. Refuse
   2. Reuse
   3. Recycle
   4. Reduce
2. Cause factors(excld.NY cost )
   1. population
   2. unsustainable resources
   3. poverty

1. aquifer

   Anotações:

   • underground water storage
2. consumption-production
3. sustainable yield

   Anotações:

   • highest use while maintaining supply
4. point - nonpoint resource
5. Environment

   Anotações:

   • Everything that affects the living organism (any unique form of live).
6. Ecology

   Anotações:

   • Biological science that studies the relationships b/w living organisms and their environment.

1. species and upper

   Anotações:

   • species community ecosystem environmensalism and so on
