Environmental Issues Discussed

GLOBAL WARMING

• Definition Global warming is the observed
  increase in average temperature if the Earths
  atmosphere and oceans in recent decades. It is
  due to the increased amounts of greenhouse gasses
  like C02. Greenhouse gasses absorb the infrared
  rays that heat the planet, instead of allowing
  them to escape the atmosphere.

Major Issues

• Increased gasses are a result of human population
  increase and inventions such as gas exhaust from
  cars.
• Increase in global temperature can result in the
  increase of sea level and amount of
  precipitation, in turn creating floods
• Other theories believe that global warming is
  within the natural cyclic fluctuations. We are
  just at a high point in temperature.

5
DEFORESTATION

• Click for Video
• Definition The conversion of forested areas to
  non-forest land use such as urban use or farmable
  land. This removal of trees with insufficient
  amounts of reforestation
• Major Issues Back to Main Page

6
Major Issues

• It alters the amount of water in the soil and
  ground water and the moisture in the atmosphere.
• We have no methods to remove CO2 and pollutants
  from the air aside from trees that clean the air
  for us.
• Runoff is faster and more flooding may occur.
• Displaces natural wildlife, sometimes with fatal
  effects.

7
ENDANGERED SPECIES

• Definition A population of something which is
  either few in numbers or threatened by
  environmental factors of becoming extinct.
• Major Issues Back to Main Page

8
Major Issues

• Loss of a species in itself, morally and
  genetically.
• Destabilizes the eco system as a whole, removing
  one species may remove a link to the food chain,
  other species who interact or depend on them may
  starve. Also, one species may become more rampart
  if not removed by another.

Definition

• Any substance which in excess is known to be
  harmful to any living organism.
• Two Categories
• Point Source Non Point Source
• Pollution Home

11
Point Source

• Usually confined sources of air and water
  pollution such as pipes that enter into a stream
  or chimney stacks emitting waste into the
  atmosphere.
• Examples Factories, Oil Spills
• Pollution Main Pollution Definition

12
Non-Point Source

• Diffused or intermittent sources of pollution,
  can be air or water.
• Non-Point sources are those that dont have
  powerful/concentrated amounts of pollution
• Examples Crop Runoff, Landfills
• Pollution Home Pollution Definition

13
Crop Runoff

• Crop runoff involves the movement of water over a
  surface.
• Crop runoff becomes pollution when harmful
  chemicals that are often placed on crops are
  carried from the fields into nearby bodies of
  water.
• Pollution Home

14
Landfills

• Landfills are used to deposit wasted material.
• Water pollution can occur when hazardous material
  makes its way into nearby aquifers and
  groundwater tables.
• Pollution Home

15
Water Pollution

• All human activities in which there are adverse
  effects to bodies of water. Natural occurrences
  such as volcanoes are typically not included as
  water pollution.
• Possible contaminants could include organic and
  inorganic matter. Pollution sources range from
  surface runoff to industrial discharge.
• Water pollution kills fish and destroys plant
  life. It can also harm human beings, besides the
  fact that we are consumers of fish. Water
  pollution can eliminate valuable drinking water
  and can create sickness and even death.

16
Effects of Pollution

• Pollution has a great impact on humans. It can
  cause cancer, immune diseases, allergies, and
  asthma. It can kill many other organisms, other
  than humans.
• Pollution can have damaging effects to the brain
  and the central nervous system.
• Environmentally pollution can decrease the
  lifespan of earths natural commodities such as
  vegetation, minerals, and wildlife.

17
Air Pollution

• Air pollution is the presence of any chemical,
  biological or physical matter that is changes the
  atmosphere.
• Human sources include burning of fossil fuels,
  automobiles, and other chemical additives
• Natural sources dust particles, smoke from
  wildfires.

Pollution from Automobiles

• Automobile pollution is a very important issue
  and many advancements have been made in the
  field. Scientists have created more efficient
  cars that can run on fuel that breaks down easier
  and emits less volatile substances.
• America is dominated with automobiles and almost
  every family has at least one.
• Although improvements have been made, this topic
  is still up for debate. Also, solutions are
  being sorted out to see which has the most up
  side. The big debate is between ethanol and
  electric automobiles.

19
Factories and Industries

• In 1007 a total of 16,462 tons of factory waste
  were not re-used as resources.
• 83 of total factory waste consists of liquid
  waste acid from the distillation of products.
• These liquid and gas waste products from
  factories greatly increases the affects of global
  warming.

Exxon Valdez Oil Spill

• One of the most devastating environmental
  disasters to occur at sea, seriously affecting
  plants and wildlife.
• The ship carrying the oil carried 53,094,510
  gallons of oil which 10.8 million gallons were
  spilled.
