Depletion of Land and Trees

2
Forestry facts

• 2-3 of forests are lost each year globally
• 60 of the benefits that the global ecosystem
  provides (water, clean air, stable climate) are
  being degraded or used

3
Deforestation

• Causes
• Cattle raising
• Agriculture or urban development
• Due to population boom

• Effects
• Spread of infectious diseases
• Interruption of ecosystem
• Erosion of soil

4
Deforestation and Wildlife

• Tropical forests cover 7 of the earths dry land
  but shelter about half of the worlds species
• Decreases habitat for wildlife species
• Extinction or Displacement

A Solution to Deforestation

• Environmental issues effect everything on this
  planet from the smallest bacteria to human
  beings.
• Life on Earth is a balance between its natural
  settings and the way we treat it.
• It is certain that finding the ultimate solution
  for deforestation is difficult, but if everyone
  contributes it will benefit the Earth in
  tremendous ways.

A Solution to Deforestation

• Reforestation
• Earth day
• Is a day that marks the first day of spring and
  to show a global appreciation to Earth in hopes
  to carry out this thought for the rest of the
  year.
• Paulownia The Environment (tree farms)
• Paulownia lumber is farmed on plantations rather
  than taken from old forests. Its alternative to
  other hardwoods that can be found in the jungles
  and rain forests.
• Recycling
• Reusing materials reduces wastes and makes new
  products

Solar Alternative in Wood scarce areas

• Families in most parts of the world each consume
  about 3 tons of wood.
• In much of Africa desertification is a risk and
  wood is scarce.
• Solar cookers use energy from the sun to cook
  food.
• Solar energy is an appropriate alternative to
  wood and other fuels because it is renewable
  daily.
• "A solar cooker can save one ton of wood per
  year." 

10
Consumption at the primary producer level
(plants)

• 90 of total energy is lost in each ascending
  move up the trophic pyramid.
• "It takes 9 pounds of feed to produce 1 pound of
  beef ready for human consumption."
• Example 2000 lbs. grain can feed 5 people per
  year or 1 person if fed to cows and consuming the
  meat.
• The world already produces enough calories for
  everyone but it is distributed unevenly
• 70 of grain grown in the US and Canada is feed
  to cattle, not hungry people. 

11
Problems in Farming

• Farmland is not being used efficiently, and
  uncultivated or abandoned arable land is
  increasing. These are due to inadequate efforts
  to increase principal farmers, and a lack of
  progress in producing feed crops through
  collaboration between crop and livestock,
  farming, among other reasons.

12
Farmland

• How do we keep what we farm from being wasted?
• How can we use the land efficiently?

13
Actions

• Promoting consumption of rice and other domestic
  agricultural produce.
• Ensuring a stable supple of food taking into
  account the whole food chain
• Promoting food education aimed at achieving ideal
  diets
• Promoting local consumption of local produce
• Securing the stability of food imports and food
  security in emergencies
• Supporting and recruiting farmers to establish an
  ideal agricultural structure

14
Genetically Modified

• GM Genetically modified food is produced from
  plants which have had their genetic make up
  tweaked in the lab. This can allows the plant to
  exist in a more hostile environment than normal.
• Controversial? The modified crops could escape
  and cross with wild plants, with unknown
  consequences.
• Benefits GM crops can be enriched with nutrients
  and they can produce bigger yields and therefore
  can use farmland more efficiently.

Solving the problem

• Personal
• Careful thought about where to and how to live
• Community (University or Village)
• Careful land use planning
• Global
• Controlled and contemplated urban development
• Efficient use of currently occupied urban areas
• Curbing population growth

19
Solving the problem

• Smart Growth (Urban Consolidation)
• Land rationing
• Extravagant Amenities
• Excessive infrastructure fees
• Approval processes
• The culture of control
• Housing Affordability

The question of how God would have us live with
what we have is one that will have to be answered
because no human solution can adequately address
the problems that we will face with growing
cities and the depleting natural resources.
