ENVIRONMENTAL ISSUES IN LATIN AMERICA:RAIN FOREST RESOURCES

Equator

“Rainforests” around the world cover approximately 5% of the earth’s total land mass. Most are found at or near

the Earth’s equator in “tropical” climate regions (biomes).

The Amazon Rainforest in South America is the world’s largest rainforest. Most of it is located in Brazil.

RAIN FOREST DEFORESTATIONHowever, today nearly 78 million acres of rain forest are

destroyed worldwide each year-about half the size of Texas.Global Rates of Rain Forest

Deforestation in Perspective:

2.47 acres per second: equivalent to two U.S. football

fields

214,000 acres per day: an area larger than New York

City

At the current rate of deforestation, the world’s rain forests will be gone in 40-45 years!

Rainforests: An Important Global Resource

Within your group, discuss and write the reasons why should we care about what is

happening to the world’s rain forests? Provide at least 3 reasons

Causes of Deforestation

Within your group, discuss and write the possible causes of deforestation.

The world’s rainforests are considered an important global

resource for three reasons:

Rainforests: An Important Global Resource

1) Its vegetation helps to clean the earth’s atmosphere of excessive Greenhouse gases. * plants absorb carbon dioxide and produce oxygen.

Think of the rainforest as an air cleaner

Rainforests: An Important Global Resource

2) Helps regulate the earth’s precipitation and temperature.

The rain forest acts like a thermostat and water facet.

Rainforests: An Important Global Resource

The world’s rainforests shelter several million

species of plants and animal.

In fact, 50% of all plant and animal species are found in

the world’s rainforests.

A DIVERSE ECOSYSTEM

3) Shelters several million species of plants-many of the ingredients found in modern medicines are found only in plants from the rainforest.

So in this sense, think of the rainforest as the world’s pharmacy.

Rainforests: An Important Global Resource

Why is this happening?

Most of the world’s rainforests are located in third-world nations

(economically underdeveloped nations).

CAUSES OF DEFORESTATION

Why would these people do something that appears to be

harmful not just to the planet,

but also to themselves in the long-term?

Causes of Deforestation :

1) Land is needed for farming to feed a rapidly growing population.* Remember, most rainforests are found in third-world nations that depend on

agricultural production to earn a living.

2) Increased global demand for timber products: Governments sell logging concessions to raise money to pay

international debts or to develop their economy/ infrastructure.

3) Increased global demand for meat products:

3) Increased global demand for meat products:Beginning in the 1960s, world cattle prices dramatically increased thus turning livestock into a valuable export. Rain forest was converted into

cattle grazing land

Since the world’s rain forests are a global resource, do we and the rest of the world have a say in how the people of Brazil and South America use or manage their natural

resources (rain forests)?

Finding Solutions- What are we to do?

• How do we balance “competing interests?

The economic needs of

developing nations

The need to protect a vital

global resource

FINDING SOLUTIONS TO SAVING LATIN AMERICA’S RAIN FORESTS

1) DEBT-FOR-NATURE-SWAP Private environmental groups help Latin American

countries pay off their foreign debt, and Latin American countries agree to protect certain portions of the rain forest from development.

Off-limits to development

FINDING SOLUTIONS TO SAVING LATIN AMERICA’S RAIN FORESTS

2) Develop “ecotourism”Tourism based on the natural beauty of the environment. This will provide an economic alternative to farming and timber exports as a means of income.

Case Studies: Brazil and Haiti

JOURNAL DIRECTIONS:Quietly read the article provided to you. Questions will follow.

1. What responsibility should companies take to ensure that down chain suppliers, particularly those in foreign countries, are not using or supporting practices that are detrimental to the environment? If such practices are used, do companies have a responsibility to make such information available to consumers? Why/ why not?

1. Do you believe the U.S. government has a responsibility to demand that businesses/ companies that do part of their business overseas inform American consumers if the manufacturing of their product was in any way detrimental to the environment? Why/ why not?

1. What can you personally do to help preserve the world’s rainforests?
