Topic: Deforestation
General Purpose: To inform
Specific Purpose: Explain to my audience the effects of deforestation

I. Introduction
a. Attention Getter: Without the help of trees, we as humans would not exist.
b. Thesis: Forests provide the earth with a regulated climate, strong biodiversity, and good nutrient rich soil for plants to strive on.
c. Reason to Listen: You as the audience should listen and understand why our planet is becoming hotter and hotter, losing specialized species, and in-turn why plants are no longer able to survive for as long as they were able to before.
d. Credibility Statement: Over the last few weeks I have be researching my topic of deforestation. Also during high school I took a class which covered deforestation and the environment.
(Transition) Deforest station effects everyone around the world.
II. Body
a. General Information: First off, deforestation is the clearing of forests or areas with trees to be converted into something else after. There are a few different ways forests are cleared. Clear cutting is simply removing everything in sight. Patch cutting is the removal of trees in specified patches. Strip cutting is removing trees in selected strips. The most environmentally friendly method is known as selective cutting. This is the removal of only selected trees, leaving the others un-harmed. The technique used most during deforestation is the slash and burn technique. This uses the basic cutting method of clear cutting, but afterwards everything that remains is burned to ash.
b. First main point: Deforestation is caused by humans clear...

... present gains are better than the long term negative effects.
b. Restate thesis: In reality forests are better left alone, forests provide the earth with a regulated climate, strong biodiversity, and good nutrient rich soil for plants to strive on.

Forests cover 31% of the land area on our planet. They produce vital oxygen and provide homes for people and wildlife. Many of the world’s most threatened and endangered animals live in forests, and 1.6 billion people rely on benefits forests offer, including food, fresh water, clothing, traditional medicine and shelter (drug war facts, Page 1).
Tropical rain forests and temperate forests are two different types of forests. They differ in density, diversity of species, regions, altitudes and their usefulness to humans. This usefulness is referred to as values. The values obtained from forests are aesthetics, scientific and educational purposes. In addition forests have the ability to absorb and store carbon dioxide released into the air from man’s endeavours. This CO2 contributes to the sudden increase in global warming. The total value of a forest ecosystem is the combined value of each individual species living within that habitat.
The ecosystem I have chosen is tropical rainforest. In the following paragraphs, I am going to firstly introduced the structure of tropical rainforest in brief, with the second part of the plant ecology and last the diversity within this ecosystem.
“In the time you can read this sentence, eight acres of tropical rain forest will have been bulldozed and burned out of existence” (Bloyd 49). However, this destruction has been neglected and overlooked for years. Many people do not understand the long-term consequences of losing the earth’s rain forests. The rain forests have provided people with many natural resources and medicines. The benefits that rain forests provide to people will be destroyed if the depletion continues to be disregarded.

Now is a critical time to address the issue of deforestation. Around the world forests are logged for timber and paper pulp. South America contains a large amount of mahogany and rosewood—highly coveted types of wood—within the Amazon basin. Forests are also cleared to make room for the planting of cash crops, such as coffee and soy, as well as livestock farms. After only a few years, overuse of these lands for crops typically causes soil erosion that quickly turns deforested regions into wastelands. Deforestation is responsible for 20 percent of global greenhouse gas emissions, which is more than all emissions all motorized transportation added together. The destruction of forests does not just threaten our climate; it threatens the livelihoods of billions of people that rely on forests for food and economic activities. The modern world relies on rainforests more than for the well-known reason. People receive many of their fruits and medicines from plant species that survive solely within the heart of a rainforest. Let’s not forget that forests also serve as habitats to wildlife a...

Environmental issues affect every life on this planet from the smallest parasite to the human race. There are many resources that humans and animal needs to survive; some of the most obvious resources come from the forests. Forests make up a large percentage of the globe. The forests have global implications not just on life but on the quality of it. Trees improve the quality of the air that species breath, determine rainfall and replenish the atmosphere. The wood from the forests are used everyday form many useful resources. Moreover, thinning the forests increases the amount of available light, nutrients and water for the remaining trees. Deforestation (forest thinning) is one of the most critical issues of environmental problems that are occurring today.
This is alarming since recent data indicates these enormous forests are land-dwelling carbon absorbers that could help to slow worldwide climate alteration. The United Nations ' Food and Agriculture Organization (FAO) estimates “eighteen million acres of forests have been destroyed worldwide;” and NASA forecasts “that if current deforestation rates are not reduced, rainforests could become entirely eradicated in a century.” The nations with substantial deforestation are Brazil, Indonesia, Thailand, Africa (The Democratic Republic of Congo included), and remote areas of Eastern Europe. Indonesia, the country with the greatest deforestation within the last century, has lost approximately forty million acres of indigenous
Deforestation, defined by biologist Charles Southwick as "the destruction of forests; may involve clear-cutting or selective logging" (p. 365), is a predominantly human-driven process that is dramatically altering ecosystems worldwide. "Clear-cutting" involves the indiscriminant removal of every single plant and tree species from within a selected area. The other major process of deforestation, "selective logging," focuses removal efforts on only specific, predetermined tree species within a chosen area. The statistics gathered about human deforestation over time are considerable, and they can be somewhat controversial. Depending on the source and the location selected, the magnitude of deforestation varies. Southwick estimates that, approximately 10,000 years ago, 6.2 billion hectares (23.9 million square miles) of forest existed on earth (p. 117). That figure is equivalent to 45.5% of the earth's total land. He further estimates that, by 1990, this amount had declined 30%, with only 4.3 billion hectares of forest remaining (p. 117). Southwick also acknowledges other estimates that place the total amount of deforestation between 50% and 75% (p. 117). NASA has similar deforestation statistics that confirm these trends. According to their website, 16.5% of the Brazilian Amazon forests have been destroyed. They also note similar magnitudes of deforestation in Southeast Asia (Cambodia, Indonesia, Laos, Malaysia, Myanmar, Thailand, and Vietnam), despite the significantly smaller total area of forest within these countries. These grim figures are somewhat tempered by the NASA finding that, over the past ten years, the deforestation rate has declined from 6,200 square miles per year to 4,800 square miles per year. Though this trend is n...
The biosphere is sufficiently larger than anyone could ever imagine. It could possibly have up to thirty million different types animals, plants, fungi, and all other organisms. Considering the ocean covers seventy percent of Earth and all of it’s matter, scientists and oceanographers have only explored and mapped five percent of it. This amazing fact shows us, humans, how little we all know about the biosphere. The life forms of the biosphere of Earth vary from animals, plants, fungi, and various others. Out of the possible thirty million different species of life forms, scientists have only discovered a small portion of over one million of them. Every single one of these species need trees...
Forests are vital for life and have many important functions. They are home to millions of species and protect soil from erosion. Along with this they produce oxygen which is vital for human life, store carbon dioxide and help control climate. They also provide humans with shelter, food and medicines vital for life.
