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.  

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.

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.

Tropical Rainforest Fast Facts Print Fast Facts Description Tropical rainforests are a type of wet, warm, humid forest. Tropical rainforests have the greatest biodiversity of any other ecosystem on earth. Some scientists believe they house more than half of all living species on earth. 90% of the species found in the tropical rainforest live in the canopy, high above the ground. Location Tropical rainforests are located in the tropics, the area around the warm equator. They are found in areas of Africa, Asia, Australia, and South and Central America. Climate The climate of tropical rainforests is warm and humid with almost continual rain. Most rainforests receive 200-1000 cm of rain a year and have temperatures that rarely drop below 22° C. Issues Tropical rainforests are quickly disappearing as a result of logging and clearing for timber, livestock grazing, plantations, and the harvest of other natural resources. 31 million hectares of tropical rainforest are destroyed each year.  That is an area larger than Poland. Status All tropical rainforests are in great danger of being destroyed. They once covered 14% of the earth’s land surface but now only cover 6%. Some scientists believe that, at the current rate of destruction, the remaining forests could be destroyed in less than 40 years. The state of tropical rainforests should be a priority for all countries and cultures since they provide and regulate the majority of the earth’s clean air and water. ©GLOBIO.org

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).

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).

Hornbills are important to the tropical rainforest of Borneo. Their bills help them eat large fruits and carry seeds to new areas of the forest

The island of Borneo started as a single volcano beneath the sea. Millions of years ago, it erupted. Over time, smaller eruptions and earthquakes joined land together to form an island. Today, Borneo is the third largest island in the world. It is twice the size of Japan. Three countries share the island: Malaysia, Indonesia, and Brunei.

Over 16 million people live on Borneo. Borneo’s landscape and wildlife are diverse and include high mountains and rugged coastlines. Most of the island is covered with dense, ancient tropical rainforest. Borneo’s rare and endangered wildlife includes the orangutan, Asian elephant, proboscis monkey, flying frog, and many species of rare plants.

Infectious diseases unwittingly brought by the Europeans or transferred from the Bantus are taking their toll amongst the pygmies: in a typical community about 20% of the population is ill. They suffer particularly from malaria, eye diseases such as endemic river-blindness, intestinal worm diseases, framboesia, lung- and viral infections and from wounds which easily go septic in this tropical environment. Many children catch measles and suffer from polio and their mortality rate is very high. Adequate health care is expensive and local resources are extremely limited. The unique pygmy people need our support. With the help of the many friends of the pygmies around the globe we provide essential health-care and assistance in education and agriculture - but with more funds we could do so much more. A little money goes a very long way. For example, for only Euro 30, -- you can send a pygmy child to school for a whole year. We can pay the teacher and provide educational materials and medical care for the pupil. We need your support
