  1. Rain forest: What makes up a tropical rain forest? Why are rain forests important? What problems are there for the rain forest? What is our responsibility to the rain forest?

  2. This power point was done using many different sources as well as personal pictures and information. The following were really helpful: Enchanted Learning http://www.mcps.k12.md.us/curriculum Virtual field trips done by Gerald R. Urquhart A power point by Paula Weigelt Jungle photos

  3. What makes up a tropical rain forest?

  4. There are two types: • Tropical rain forests receive more than 80 inches of rain a year. Some rain forests can receive as much as 200-400 inches of rain a year! These forests also have large amounts of humidity, or water vapor in the air. • Temperate rain forests are forests that have very distinct seasons and a more moderate climate. Rain occurs evenly throughout the whole year.

  5. Rain forest Comparisons • Tropical • 200”-400” rain per year • broadleaf on trees • hundreds of species of trees • temperature constant around 75ºF • endangered • Temperate • 100” of rain per year • needle leaves on trees • 10 - 20 species of trees • temperature average 60ºF • endangered

  6. The climateof a tropical rain forest is very hot and humid so the animals and plants that exist there must learn to adapt.

  7. Where are tropical rainforests located?

  8. Rain forest layers In the emergent layer, trees can be 200 feet high. Most trees are broad-leaved, hardwood evergreens. Sunlight is plentiful.   Animals found here are eagles, monkeys, bats and butterflies. The canopy layer forms a roof over the two remaining layers and is a very dense layer.   The leaves on most trees are smooth and come to a point. Food is abundant for animals such as snakes, toucans and tree frogs. Little sunshine reaches this layer so the plants have to grow larger leaves to reach the sunlight. Plants in this area seldom grow to 12 feet. Animals that live here include jaguars, red-eyed tree frogs and leopards and many insects. This layer is very dark, so no plants grow here,  Things decay very quickly here.  A leaf that might take one year to decompose in a regular climate will disappear in  only 6 weeks. This is the home for giant anteaters.

  9. Why are they important? • These incredible places cover only 6 % of the Earth's surface, but MORE THAN 1/2 of the world's plant and animal species live there! • At least two-thirds of the world's plant species, grow in the rain forests.

  10. In addition: • We eat many foods from the rain forest and many medicines are made from ingredients found only in these areas. • Cinnamon • bananas • rubber • coffee • cocoa and many more

  11. Of the millions of animal species in the world, over half are found in the rain forest and nowhere else on Earth. Special Creatures MACAWS

  12. ZOG-ZOG More Creatures

  13. All is quiet and peaceful in the forest -or is it?

  14. People of the Rainforest People have lived in the rain forests for thousands of years. They live in harmony with the forest, plants and animals. Their traditions and customs are unlike other people.

  15. Homes in the forest are very different. They don't need walls on their houses because it doesn't get cold t here. Natives don't need much privacy at all. Privacy is a lot different than what you may be used to and we do go into houses without asking.

  16. Children are expected to do lots of work and they get up early in the morning. The girls look after their little sisters, brothers, nieces, or nephews. They also help cook, grate manioc, carry heavy backpacks, and get water.

  17. The boys in the village have to do some work, too. They fish, farm, and weave baskets with the men in the village. They also spend much time in the jungle as part of their learning and training to become excellent hunters and providers for their families.

  18. In their free time, both boys and girls love to go swimming in the river, and there are plenty of rivers around in the rain forest. They also like to watch the animals in their village. The girls like to play with their hand-made dolls (since there are no stores around here to buy them). Boys like to shoot their bows and arrows and play in the forest.

  19. Guess who is in the yellow rain coat? Why is the rain forest so valuable?

  20. How has it helped us? • Fifty percent of the medicines used every day come from rain forest plants. • The corn plant originally came from the forests in Mexico and South America. • Rice came in Asian rain forests. • Orange juice, tea, eggs, and bananas originally came from Asian rain forests. • Over 50% of the fruits you eat originally came from tropical rain forests.

  21. Products we get with help from rain forest resources...

  22. What problems are there for the rain forest?

  23. The Rain Forest is in Trouble: In addition to being one of our most precious natural resources, tropical rain forests are among the most endangered habitats on earth because of deforestation. Causes of Deforestation: * clearance for roads and railways * forest fires * mining and drilling for fuel wood * international timber trade *collection and clearance for living space Humans already have destroyed half of the rain forest area, with most damage occurring in the last 200 years.

  24. A delicate ecosystem destroyed • Rainfall is absorbed by the trees.It is pulled up to the canopy where it evaporates into the air. • Trees and plants receive most of their nutrients from decaying matter such as fallen leaves and organic debris. • Plants and trees hold down the topsoil. This keeps it from washing away in heavy rains. • When the land is cleared and crops are planted the soil doesn't stay fertile for long because it doesn't have nutrients from the decaying matter. • Once plants are removed, heavy rains wash away the topsoil.

  25. By Deforestation

  26. Rain forests are important to everyone on the planet-not just to those who live in or near them. They help control the world's climate. When the rain forests are burned and cleared, carbon is released into the atmosphere.Carbon dioxide in the atmosphere prevents the sun’s radiation from escaping back to the atmosphere. This causes the weather to be much hotter on the whole planet. • (This is called the greenhouse effect.)

  27. When the beautiful forest is gone where do the animals go?

  28. What is our responsibility to the rain forest?

  29. Can you help?

  30. WATCH OUT FOR OUR EARTH • WAYS THAT YOU CAN HELP TO SAVE THE RAIN FOREST: • Write letters to your senators or representatives to let them know that you are concerned about rain forest destruction. • Ask that they support programs that help protect tropical areas throughout the world. • Write letters to other organizations that can help.

  31. ANOTHER WAY THAT YOU CAN HELP TO SAVE THE RAIN FOREST: • Go in with some friends and buy an acre of rain forest. The Nature Conservancy's "Adopt-an-Acre Program" lets you purchase the protection of an acre of rain forest in a specific nature preserve.

  32. WATCH OUT FOR OUR EARTH • MORE WAYS THAT YOU CAN HELP TO SAVE THE RAIN FOREST: • Turn off the lights or TV when you leave a room • Recycle: paper, cardboard, plastic, glass, metals--everything you can! • * Walk or ride your bike instead of driving.

  33. Think about all the changes that would happen if we lose the rain forest

  34. Forest PeopleForest people will lose their homes, and their culture. Their knowledge of the forest is also lost . Last Songbirds Thesongbirds, which help farmers in the U.S. by eating insects, will no longer winter in tropical forests. Changed ClimateBurning huge areas of rainforest releases carbon, which causes changes in wind currents and rainfall around the world. Undiscovered MedicinesPlants that might provide new medicines extinct before they can even be studied. ExtinctionThousands of species of rainforest plants and animals will be lost.

  35. What will you do about the rain forest now?

  36. Are you ready to do more exploring? Here is a website you can use that is really neat. You are finished with the slide show at this point. http://www.bsrsi.msu.edu/rfrc/tour/active.html
