Chapter 17,18 Water Pollution

In early times the forest covered nearly all of the earth's surface. As recent as the 19th century tropical rain forests covered 20% of all dry land but was cut down to about 7% by the end if the 20th century.
 Due to population growth as well as Industrial growth the demand for the Rainforest resource's has been huge.
A historical aspect of rain forest deforestation took place mostly before the year 1950. (Michael Williams of History today.) During the 450 years from 1492 to c.1950 European influence has been dynamic.

Each environment is directly affected by pollutants and depletion of trees. In the far North the pine  forest are diminishing due to clearcutting practices. Railroads are another source for clearcutting, these railroads add to pollution and emmisions that are harmfull to our ozone layer.

Most distruction is seen in the North American rain forests because these forests are in lowland areas they are more easily acessable and prone to mans pollution. The rainforests that are least affected are the ones in higher elevated areas with rugged peaks.

Greenhouse gases are increased in the more populated areas of the clearcutted rainforests.Because of overpopulated areas of surrounding villages the forests are losing their trees as well as being continually contaminated.

The tropical rainforest have been managed by mankind for thousands of years to sustain productive agriculture for the human population. 12 percent  of the Amozon is anthropogenic in nature due to the ongoing attempts to sustain ecenomic growth by developing communities and industries.

Disturbance by humans is not new to the Amozon. Indgneous people have attempted to sustain the resources of the forest which is duplicated today in different ways.
Patchworks, annual crops, pasture land, secondary growth are ways to sustain these forests. Replanting on a regular basis is a key practice to sustaining the forests.

The farming of feilds secondary to older forests can promote regrowth when clearcutting.
With a long history of disturbance by humans about two-fifths of rainforest deforestation is by shifted cultivator, usually in overpopulated areas.

Creating conditions that will initiate the growth of fruit trees and vine forests is one way that the rapid decline of these forests can be helped. Monocultures which are single crop fields, that must be replantedon a regular basis to sustain yeilds, are another way to sustain these lands.

forests with yeilds such as coffee rubber and pepper can be sustained by only farming small areas and then replanting immediately.

Important facts about the area of tropical rainforests include but are not limited to the following;

  • Over 750 species of trees live in these forests.
  • There are over 1500 different kinds of flowering plants in the tropical rainforest.
  • 125 species of mammals exists in the tropical rainforest.
  • There are more than 100 kinds of reptiles.
  • There are 60 amphibians.
  • Countless species of insects exists.
  • There are about 150 species of butterflies.

How does the rain forest affect the earths water?
A flow of about twenty eight billions of gallon of water are known to flow out of the Amazon into the Atlantic ocean every minute.
Over nine feet of rain a year and fifty percent of the rain absorbed into the atmosphere, the affect on the worlds water supply is huge.
Deforestation affects all the positive benefits of the Amazon rainforest industries such as mining, cattle ranches and logging.

As recent as the 19th tropical rainforests covered 20% of all dry land area of the Earths surface that number is down to an estimated 7% . The demand for the rain forest as an economic and social resource has been huge in numbers causing more clear cutting activity which increases pollution levels which the rainforests at one time helped to prevent.
A historical aspect of rainforests is that deforestation took place mainly from 1492 to 1950 . (Micheal Williams of history today)

Rain forests act as a pollution sink in a way that greenhouse gas is removed from the atmosphere by soaking up carbon dioxide and neutralizing it.
Air Pollution dramatically affects the ability of these large bodies of forestry to do this. Greenhouse gases are stored and released to further contribute to global warming.

Acid rain releases toxic  substances such as aluminum into the soil. Acidic water dissolves the nutrients in the soil and washes them away before the trees and plants are able to benefit from these needed nutrients.

Air quality is adversely affected because of the trees ability to trap carbon and other particles.
(E-how health-Lillian Wade e-how contributor.

Logging depletes the trees, logging is a result of large industrial demands. As a result of depletion of the earths trees pollution of the earth is increased because of the important role that all rain forest play.

Agricultural contribution to rain forest pollution is as follows;
  • The slash and burn method to clear cut forests at a rapid pace depletes the earths trees and its ability to filter pollution.
  • The soil becomes poor as a result of cut and clearing of rain forests resulting in farmers seeking new land to cut and clear.
  • Increase of waste left by humans contaminates water and soil at an increased rate making it more difficult to filter air which then affects our water.

Mining has also caused increased pollution because of the mercury used in extracting the gold during the gold rush of the 1980s in Brazil's Amazon polluted waterways causing the fish to be inedible.
Mining included blasting, which released particles and noxious fumes, wind spread asbestos which also increased pollution of both air and water.

Hydro electric dams is a major source of energy in developing rain forest countries.
Dams flood areas of the rainforest's. They also increase water borne diseases. Another consequence of dams is that they trap nutrients such as silt which is crucial for aquatic life thus damaging downstream eco systems.
Reduced levels of silt cause soil erosion needed to fight water contamination.

Mankind has extensive influence on the ever-changing environment. As the most untouched and pristine ecosystems remaining on earth. The collective photosynthesis by the rainforest's trees let of a little bit of needed oxygen in the atmosphere every day.

Rainforests are also the biggest natural greenhouses on earth providing and supporting life within its environment by producing its own foods. As we come to shortages in foods throughout the earth scientists are now searching for answers within the rainforests of the earth.

Rainforest also known for the worlds biggest pharmacy provide many medicinal remedies' that many third world people still depend on today. The rainforests of the world need to be a higher priority today so that scientist can learn how to monitor the earths climate changes.

Rainforests should also be closely protected because the way these great bodies of nature are able to sustain life and used as an example of how to maintain the worlds ecosystem. Protection should also extend to the many different indigenous tribes that continue to live and thrive in these environments.

It is estimated nearly half of the worlds species of plants, animals and microorganisms will be destroyed or severely threatened over the next quarter century. Much unrealized potential lies within the lush floors of these forests. Because of the complex nature of undiscovered biodynamic compounds sustaining and protecting these forests can only be in mankind's best interest.

Chapter 13..14 Restoration Ecology

The rain forest should be saved because they are homes to those monkey's with the Doc Holliday mustaches...I think they are called Emperor Tamarins. Also, three toed sloths, and possibly Bennett's Tree Kangaroos. The world is a much better place with animals as delightful as these. Without them we would all be very sad. At least I would. And so it would make me happy were we to save the rain forests and protect the homes of these wonderful animals.

More so than my personal affinity for the denizens of the deep jungle, the rainforests are essential to the health of mother earth. It is believed that the rainforests store over half of the whole world's watr supply! They act like a huge sponge, absorbing the worlds water and releasing it back into the environment. The trees also act as huge air filters for the planet.

The rainforests are also immensely important resources, So many medicinal discoveries are made in the rainforest...over 25% of our modern medicines originate from rain forest plants. I wonder how much more there is to be discovered.

Restoration of all species such as these majestically creatures is key in keeping the eco system at its most primal delicate balance. Every species has a role and every living plant and insect is impariitive in its role to restore ecological balance.

Today there are fewer than 250,000 indigenous people left in the Brazillian Amazons.

Food and Hunger chapter 9,,10

Food and Hunger


Indigenous people of the rainforest suffer on some level with hunger .
The homes of many tribal cultures these forests are consistently subjected to many exploitations.
although most native societies have been destroyed s is is estimated there are still more than 1,000 rainforest cultures that still exists today.

Right being disregarded these forests continue to be exploited for all its abundant resources. Tribes such as the Penans society which is a hunter-gatherer tribe in south-East Asia that number about 10,000. This tribe relys on fruits and vegetables of of the forest as well as many fungi wild greens and edible palms.

Preservation of the forest is a culturally embedded value passed along to generation after generation of the Indigenous people.  Preservation of the forest is not a value of intrusive Governmental and Private entities that continue to take from the forest precious resources such as medicinal plants and organic food that provide for its habitat.

Animals that face a shortage of food in a rainforest do what is called estivate, which is similar to hibernation as a way to cope with food shortage. A continuous battle and competition for food many species adapt to their surroundings in a physical manner such as changing shape color or size to fit into their surroundings and example being stick insects which become the color and shape of surrounding aggregation.

Different species of the forests develop physically to adapt to their survival needs such as Tucan birds that have large, hard beaks to pick, grind and eat various types of leaves and shells. An important aspect of food competition in the rainforest environment is adaption of food consumption and survival techniques that will prevent you from becoming food.
