Interdependency Within the Modern World

Interdependency Within the Modern World

• The Danger of Water, Soil and Plant Pollution
• Chapters 4,5,6

Everything is connected

Chemical Pollution in Water

• THE BATTLE TO SAVE OUR WATER
• Pesticide use contaminate many water sites
  through pesticide runoff and deliberate
  application.
• Chapter 4

The beauty of one of natures greatest resources

And this is the havoc caused by insecticide
pollution

• Pollution of the environment negatively affect
  necessary water resources.
• Water sources have already suffered through
  significant pollutants by way of radioactive
  wastes and nuclear fallout. The addition of
  chemical pesticides have furthered the pollution
  of our waters.
• The first major problem with this type pollution
  are their aims to destroy particular plants and
  insects. Pesticides deliberately applied to water
  sources unnecessarily kill off pertinent species
  of fish and decrease species diversity.

7

• The problem with this unadulterated killing are
  the effects it has on species diversity
  pollution kills species in their natural habitat
  and inhibit their reproduction causing immense
  population declines. As chapter 53.2 states,
  species diversity is fundamental in community
  structure and interruptions could have horrid
  effects.
• Concept 53.2 relays dominant and keystone species
  exert strong controls on community structure. In
  chapter 4 Carson relates that waterfowl
  populations have significantly declined in the
  Far West and damage could be irreplaceable. The
  species on which these waterfowl fed on were
  contaminated. However what about other species of
  fish controlled by the waterfowl? These species
  will now go unchecked. Other examples may include
  the decline of keystone species and leaving
  dominant species unchecked.

• The problem of water pollution is part of the
  problem of global pollution. Infiltration of
  chemicals into water have made problems of modern
  water purification with many chemicals still
  present in filtered water.
• Evidence of this exists in a case where sample
  drinking water from an orchard area in
  Pennsylvania contained enough pesticides to kill
  all test fish in only four hours. This "drinking"
  water also proves harmful to humans and again
  disrupts the ecosystem. pg 1200
• Water pollution is invisible and the deaths it
  cause usually go undetected.

Its Everywhere!!!!!!

• Pollution in our groundwater

• Widespread groundwater contamination seems to be
  the most pertinent problem in water pollution.
• Groundwater contamination leads to pollution of
  streams, lakes and rivers in areas not even
  treated with insecticide.
• As stated in Chapter 54.5 groundwater
  contamination directly effects marine ecosystems
  and are supplies of drinking water poisoning
  could be a very real way of killing off many
  forms of life.

Disrupting the Earths Foundation

• Widespread Pollution of Our Soil
• Chapter 5

Not a happy Earth

• Soil serves a dual purpose. It is the birthplace
  of many life forms and also serves as a habitat
  for many organisms including many bacteria and
  fungi.
• Soil constantly changes. It is always taking part
  in variant nutrient cycles.
• Insecticides in soil such as DDD,aldrin,lindane
  and heptachlor among others disrupt the
  continuity of nutrient cycles occurring in the
  soil. Without the nutrients present the cyclic
  patterns of the soil, plants would starve and
  die.
• Soil plays a vital role in nitrogen cycles and
  insecticides inhibit nitrifying bacteria from
  continuing this process thus interrupting
  nitrogen supplies of organisms. Arsenic also is
  very poisonous to soils and its effects are
  permanent

15

• As lifes birthplace, soil contamination affects
  all living things.
• Plant tissues absorb insecticides within the
  soil, causing infected plant life they may harm
  them and the consumers that feed on them.
  Poisoned soil poisons plants poisoned plants
  poison animals poisoned animals poisons you and
  meScary isnt it?
• The Rivet Model as discussed in Chapter 53.5
  interdependence within communities and ecosystems
  and shows how changes in one area can affect the
  entire ecosystem.

Interdependence

• Connections between pollution of water, soil and
  vegetation

• Water, soil and vegetation are the materials
  supporting our modern world so taking care of
  them should be a priority.
• Herbicide sprayings eliminate many unintended
  targets. Sprayings are assumed to be focused on
  attack of one particular plant but often the
  insecticide attack is a blanket one taking
  victim many unintended plant life and destroying
  habitats. Carson observes how sprayings are
  constantly used as a blanket cure-all and are
  therefore abused.

19

• Carson concludes this chapter with the
  interdependence between vegetation, organisms and
  soil and the importance of taking care of each
  intricate part.
• Chapter 50.1 directly correlates with this
  principle and encourages the use of the
  precautionary principle when dealing with the
  environment. The precautionary principle advises
  people to carefully consider potential
  consequences of actions.
• For example, the book makes notice of a sage
  eradication project by the government in the
  West. The destruction of this essential plant,
  affected the eating patterns of many animals
  including antelope, mule deer, and grouse. Not
  taking to account eradication would have on these
  animals the government continued with the program
  and disrupted a vital system in a community.

20

• The interdependence of ecosystems warrants
  precautions to be taken to ensure the safety of
  the Earths animals, water and soil. Yes it
  sounds rudimentary, but we only have one Earth
  we should protect it to the best of our
  ability!!
