What are the three major causes of deforestation, and which is the most significant?

80% of all land is cleared for cattle grazing, which is the most important cause of deforestation in the Amazon Rainforest. Brazil is one of the world's biggest exporters of beef, and land is cleared for large commercial herds. Commercial and subsistence farming also cause deforestation. Soybeans, sugar, and palms all are grown commercially. Poor residents often practice slash-and-burn agriculture, which can be very damaging. Finally, deforestation occurs when trees are cut down for their wood, often illegally. Much of this wood, including mahogany, is very valuable.

Write a short letter to the president explaining why we should protect the rainforest.

Dear Mr. President, It is very important that we work harder to protect the rainforest. Although it is far away, it is important to us. The plants in the Amazon have provided drugs for fighting cancer. The Amazon is also home to about 20% of the world's water. The trees release that water into the atmosphere, preventing drought. Rainforest trees store carbon dioxide and produce oxygen. Scientists are concerned that cutting down these trees could lead to global warming. Finally, the rainforest is home to about half a million people who depend on it to survive. Sincerely, Suzy Student

The drug war in Mexico began in the 2000s when drug cartels began fighting for control of the drug trade into the US. This has been very difficult to stop. Police officials are bribed to ignore violence; those who refuse bribes are at risk of being assassinated or having their families murdered. As a result, the Mexican government has sent thousands of soldiers to the area to try to stop the violence. Soldiers often must wear hoods to keep their identities secret. Journalists who have exposed corruption and bribery have been killed. Thousands of Mexican citizens have been killed as well. The US spends more than $500 million a year helping Mexico fight the cartels.

What are countries like Brazil doing to protect rainforest resources?

Brazil has placed more than 100 million acres of rainforest under a protected status to prevent development and to limit deforestation. This appears to be working, as deforestation peaked in 2004 and is down about 60%. Laws protecting endangered animals also have been passed, but these can be difficult to enforce. Some animals, like the jaguar, kill livestock, prompting farmers to kill them when they have the chance.

Why is protecting biodiversity in the Amazon Rainforest so important?

The Amazon Rainforest is home to some of the world's greatest biodiversity. The Amazon is home to thousands of different species of trees, plants, animals, and insects. New species are continually being discovered, and many of these have proven to be beneficial to humans. Over 25% of prescription drugs sold in the US are made with ingredients found in the rainforest. These drugs help treat diseases such as leukemia, breast cancer, asthma, and high blood pressure
