AMAZON QUICK FACTS obtained from a variety of sources, simply organized, none verified and not meant to be the definitive guide to Amazon facts. The Amazon is the largest and densest rainforest on earth The Amazon covers 2.5 million miles, about the size of the USA west of the Mississippi If Amazonas were a country, it would be the 9th largest on earth Each minute the Amazon River discharges 3.4 million gallons of water into the Atlantic, 14 times the discharge of the Mississippi The Amazon runs 4007 miles from its origin in the Andes to the Atlantic, making it the second longest river on earth During its journey it touches and-or travels through 8 countries There are 200 major tributaries of which 17 are more than 1000 miles long and 10 of which discharge more water than the Mississippi Its vegetation represents about 1/3 of the remaining forest on earth and provides about 15% of the world's new oxygen Scientists have catalogued: 2500 species of fish 1500 species of birds 1800 species of butterflys 4 types of big cats 200 species of mosquitos 50,000 species of higher plants

Mangroves are woody trees or shrubs that grow in mangrove habitats or mangal (Hogarth, 1999). The mangrove is often considered a type of biome. Mangrove habitat is exclusively tropical and tidal, and therefore having soil or sediment that is water-logged and saline or of variable salinity. Areas where mangal occurs includes estuaries and marine shorelines. A wide variety of plant species can be found in mangrove habitat, but some 54 species in 20 genera, belonging to 16 families constitute the "true mangroves" — species that occur exclusively in mangrove habitats and rarely elsewhere (Hogarth, 1999).

Biomes are defined as "the world's major communities, classified according to the predominant vegetation and characterized by adaptations of organisms to that particular environment" (Campbell 1996).

A biome is an area on the earth's surface that has a certain set of characteristics. There are seven kinds of biomes in the world: tundra, taiga, temperate forest, tropical rainforest, desert, grassland, and ocean. The map above shows where each of these biomes can be found around the world. Although it does not appear in the key, the ocean is represented by the blue area on the map.

A fundamental classification of biomes is into: Terrestrial (land) biomes Freshwater biomes Marine biomes

Biomes are climatically and geographically defined areas of ecologically similar climatic conditions such as communities of plants, animals, and soil organisms,[1] and are often referred to as ecosystems. Biomes are defined by factors such as plant structures (such as trees, shrubs, and grasses), leaf types (such as broadleaf and needleleaf), plant spacing (forest, woodland, savanna), and climate. Unlike ecozones, biomes are not defined by genetic, taxonomic, or historical similarities. Biomes are often identified with particular patterns of ecological succession and climax vegetation (quasi-equilibrium state of the local ecosystem). An ecosystem has many biotopes and a biome is a major habitat type. A major habitat type, however, is a compromise, as it has an intrinsic inhomogeneity. The biodiversity characteristic of each biome, especially the diversity of fauna and subdominant plant forms, is a function of abiotic factors and the biomass productivity of the dominant vegetation. In terrestrial biomes, species diversity tends to correlate positively with net primary productivity, moisture availability, and temperature.[2]

These days, it takes more than textbooks and pencils to be a schoolgirl in Afghanistan—it also takes tremendous bravery and tenacity.

Rainforests are disappearing very quickly. The good news is that there are a lot of people who want to save rainforests. The bad news is saving rainforests is not going to be easy. It will take the efforts of many people working together in order to ensure rainforests and their wildlife will survive for your children to appreciate and enjoy.

Teach others about the importance of the environment and how they can help save rainforests. Restore damaged ecosystems by planting trees on land where forests have been cut down. Encourage people to live in a way that doesn't hurt the environment Establish parks to protect rainforests and wildlife Support companies that operate in ways that minimize damage to the environment

Cold, snowy, windy. When you hear those words they make you think of mountains. The Alpine biome is like winter is to people in New England; snow, high winds, ice, all the typical winter things. In Latin the word for 'high mountain' is 'alpes'. That is where today's word alpine comes from. Alpine biomes are found in the mountain regions all around the world. They are usually at an altitude of about 10,000 feet or more. The Alpine biome lies just below the snow line of a mountain. As you go up a mountain, you will travel through many biomes. In the North American Rocky Mountains you begin in a desert biome. As you climb you go through a deciduous forest biome, grassland biome, steppe biome, and taiga biome before you reach the cold Alpine biome. In the summer average temperatures range from 10 to 15° C . In the winter the temperatures are below freezing. The winter season can last from October to May. The summer season may last from June to September. The temperatures in the Alpine biome can also change from warm to freezing in one day. Because the severe climate of the Alpine biome, plants and animals have developed adaptations to those conditions. There are only about 200 species of Alpine plants. At high altitudes there is very little CO2, which plants need to carry on photosynthesis. Because of the cold and wind, most plants are small perennial groundcover plants which grow and reproduce slowly. They protect themselves from the cold and wind by hugging the ground. Taller plants or trees would soon get blown over and freeze. When plants die they don't decompose very quickly because of the cold. This makes for poor soil conditions. Most Alpine plants can grow in sandy and rocky soil. Plants have also adapted to the dry conditions of the Alpine biome. Plant books and catalogs warn you about over watering Alpine plants. Alpine animals have to deal with two types of problems: the cold and too much high UV wavelengths. This is because there is less atmosphere to filter UV rays from the sun. There are only warm blooded animals in the Alpine biome, although there are insects. Alpine animals adapt to the cold by hibernating, migrating to lower, warmer areas, or insulating their bodies with layers of fat. Animals will also tend to have shorter legs, tails, and ears, in order to reduce heat loss. Alpine animals also have larger lungs, more blood cells and hemoglobin because of the increase of pressure and lack of oxygen at higher altitudes. This is also true for people who have lived on mountains for a long time, like the Indians of the Andes Mountains in South America and the Sherpas of the Himalayas in Asia. bibliography: "Himalayas", http://encarta.msn.com/find/, (June 2000).

So what can you do to help the rainforest? 1) Choose wood carefully Make sure that your home and school do not buy wood that comes from rainforests, such as mahogany, ivoko, sapele, vamin and rosewood. Ask the salesperson where the wood came from. You can check in the 'Good Wood Guide' published by Friends of the Earth. 2) Spread the word! You can show the rest of your school what you have learned about the rainforests by making a display! Colour in the rainforest sheets that you can download here, or you can draw pictures and write your own stories about the people and animals who live in the rainforest. 3) Protect an Acre By raising money you can help protect an acre of rainforest. For a £25 donation you will receive a certificate to display in your classroom and an information pack on the area of land that you have helped to protect.

Of these varying Amer-Indian people living in the Amazon Rainforest, one of the largest groups is the Yanomami.  “Yano” translates to “communal house”.  Their village life is centered around the “yano”, or communal house.  The “yano” is a large, circular shelter constructed of vine and leaf thatch, which has a living space in the middle.   Village activity revolves around the main house which has multiple living quarters built in the center.
