Title: How Can We Create a Better Ecosystem?


1
How Can We Create a Better Ecosystem?
2
Unit Questions
  • What problems do ecosystems currently face?
  • What are strategies to prevent problems?
  • Are these methods accomplishable?
  • Can we restore original ecosystems?
  • What will future ecosystems look like?

3
Creating A Better, Cleaner Ecosystem
  • Presented by Shane Bridges

4
Overview
  • Problems that the ecosystems face
  • Restoration and Prevention Methods
  • Putting these methods into effect
  • Restoration Limitations
  • The Future

5
Problems in the Ecosystems
  • Deforestation
  • Industrial Development
  • Overfishing
  • Pollution
  • Degradation

6
Deforestation
  • Deforestation the removal or cutting down of
    trees.
  • More than half of the world's timber and 72 of
    paper is consumed by 22 of the world's
    population (the United States, Europe, and
    Japan).
  • Every hour, at least 4,500 acres of forest fall
    to chain saws, machetes, flames, or bulldozers.

7
Industrial Development
  • Industrial Development Development of factories
    for large-scale production of consumer goods.
  • These factories consume large amounts of economic
    resources and distribute pollutants into the
    environment.
  • Governmental guidelines and restrictions exist,
    but do little to stop introducing pollutants into
    the ozone layer.

8
Overfishing
  • Overfishing catching too many fish for the
    system to support
  • http//overfishing.org/pages/what_is_overfishing.p
    hp
  • Over 25 of the worlds fish stocks are either
    overexploited or depleted

9
Pollution
  • Pollution the introduction of contaminants into
    a natural environment that causes instability,
    disorder, harm or discomfort
  • Happens in the form of industries, littering,
    dumping, etc.

10
Degradation
  • Degradation the deterioration or depletion of
    resources
  • Can lead to the destruction of ecosystems and
    extinction of wildlife
  • Affects air, water, and soil

11
Restoration
  • A return to original settings
  • Can be done to certain extents
  • gt hard to recreate
  • gt not perfect recreations
  • Environmental groups
  • gt ideas/strategies some good, some bad

12
Prevention
  • Methods to prevent the loss or depletion of
    resources
  • Use less
  • Recycle
  • Use alternatives

13
Implementing Effective Strategies
  • Environmental Groups
  • Worldwide - Intergovernmental Panel on Climate
    Change (IPCC)
  • United Nations Environment Programme (UNEP)
  • Earth System Governance Project
  • RegionalEuropean Environment Agency (EEA)
  • Partnerships in Environmental Management for the
    Seas of East Asia (PEMSEA)
  • Many strategies, many alternatives

14
Restoration Limitations
  • Hard to recreate
  • What is the original?
  • Conflicts (how to)
  • Lack of effort
  • Human need

15
The Future
  • What does the future look like?
  • Will we be able to improve ecosystems?
  • Can we maintain them better?
