Environmentalists are concerned about loss of biodiversity due to the destruction of the forest, and about the release electricity outage houston tx of the carbon in the vegetation, which would accelerate global warming. Amazonian evergreen forests account for about 10% of the world’s productivity on land and 10% of the carbon stores in ecosystems [5]—of the order of 1.1 × 10 11 metric tonnes of carbon. [6] Amazonian forests are estimated to have accumulated 0.62 ± 0.37 tons of carbon per hectare per year between 1975 and 1996. [6]

Some people have calculated that it may even pay to save the forest. They said that one hectare of Amazonian forest in Peru is worth about US $6280, if it is used to harvest fruits, latex and timber (wood). If all the wood is cut down for timber, it has a value of about US $1000. Obviously, this can gas news australia only be done once; it is not sustainable. When the forest has been cleared, the hectar of land can be used as a pasture, and is worth about US $148. Not all people agree on the study; some have questioned the assumptions behind it.

9,169 square miles of rain forest were cut down in 2003 alone. In Brazil alone, European colonists have destroyed more than 90 indigenous tribes since the 1900s. [ source?] With them have gone centuries of knowledge of the medicinal value of rainforest species. As their homelands z gas tecate continue to be destroyed by deforestation, rainforest peoples are also disappearing.

Once the process of vulcanization was invented, companies began to make many kinds of new rubber products, such as boots and seals for machines. American and European companies began buying large amounts of latex from Brazil. This boom in Brazilian rubber began what are the 4 gas giants in the solar system around 1870, but the need for automobile tires brought the greatest wealth to the new rubber producers. [7]

Thousands of people moved to the rain forest to work collecting rubber. Most of these people were hired by rich rubber merchants. The rubber merchants loaned them money to come down the river and power outage houston zip code buy tools. Each merchant’s collectors had to sell the rubber only to their rubber merchant at low prices and buy supplies only from them at high prices. That meant the collectors were always in debt to their merchant and could not leave to do something else. The rubber merchants quickly became very rich.

The center of the rubber trade was Manaus on the Rio Negro. [7] It became first a boom town and then a beautiful, wealthy city. It had electricity before most of the cities in the United States did. [7] The newly rich merchants built huge expensive homes and brought in automobiles to travel on the city’s few roads all 4 gas giants names. They built a magnificent opera house with crystal chandeliers and decorated tiles brought all the way from Europe. [7]

However, the rubber boom only lasted about forty years, ending by 1913. [7] Some men had taken the gas yoga seeds of the Amazon rubber trees and began growing them in the Asian rain forests. The trees grew well there, and they could be grown on plantations. The insects that could destroy them were in South America. So the price of rubber began to fall, and the rubber boom stopped.
