Environment Problem

Environment Problem

1. SBC Key

   • rely on Solar energy
     • – 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
   • protect Biodiversity
     • – Large variety of species – Many ecosystems • Deserts • Forests • Oceans • Grasslands – Species and systems renew soil and purify air and water.
   • NOT disturb Chemical Cycling
     • –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

2. Natural Capital

   • services
     • purification
     • nutrient cycle
       • From the environment to organisms and back to the environment
   • resources
     • (non)renewable energy
       • renewable
         • –days to centuries –Water –Air –Grasslands –Forest –Soils –Fish populations
     • based on human
     • Perpetual
       •  – renewed continuously – Solar energy
   • Photosysthesis

3. Ecological Footprint

   • – 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
   • per capita ecological footprint(area)
     • Average ecological footprint of an individual in a given area
   • Ecological deficit
     • Total ecological footprint greater than biological capacity for resource renewal and absorption of wastes and pollution

4. IPAT IMPACT

   • Population
   • Affluence
   • Technology
   • I = P + A + T

5. Pollution soln

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

6. TECHNCAL TERM

   • aquifer
     • underground water storage
   • consumption-production
   • sustainable yield
     • highest use while maintaining supply
   • point - nonpoint resource
   • Environment
     • Everything that affects the living organism (any unique form of live).
   • Ecology
     • Biological science that studies the relationships b/w living organisms and their environment.

7. focus on

   • species and upper
     • species community ecosystem environmensalism and so on
