1 Rainforest revision

2 Here is the answer: what is the question?  Adaptation  Emergent  Forest floor  Sustainable development  Eco tourism  Cattle ranching

3 What is a Rainforest?  Rainforests are very dense, warm and wet forests  They are havens for millions of plants and animals  They are very important in the ecology of the Earth as the plants of the rainforest generate much of the Earth’s oxygen

4 Tropical Rain Forests  Tropical rain forests are found in a belt around the equator, where temperatures and rainfall are very high all year round  There is very little variation between the seasons  They will have an even distribution of rainfall annually  Warm temperatures with less variation during the year  The best known rain forests are found in tropical regions between the Tropics of cancer and Capricorn

5 Key term: Ecosystem The way in which all living components (plants, animals, soil, etc) interact. Example of a question: What impact would removing the trees have on other components of the tropical rainforest ecosystem (4)

6 An ecosystem is a living community of plants and animals within a natural environment. The distribution of ecosystems across the world is dependent on the climate and soil they rely on in order to grow.

7 Example of a question: Describe the distribution of tropical rainforests (4)

18 Explain the consequences of the deforestation of the Amazon rainforest (6)

19 Impacts of Deforestation Physical:  On water cycle – more surface runoff, less rainfall, increased sediment load, greater flood risk.  On soils – more erosion, gulleying, landslides, leaching, reduced fertility.  On climate – carbon dioxide increases, increased daily range of temperature, rainfall decrease, reduced oxygen.

20 Examples of questions:  Define sustainable development (2)  Describe a sustainable development scheme designed to protect the rainforest (4)

21 Impacts of Deforestation Socio-economic and cultural:  Loss of traditional way of life.  Loss of land.  Indigenous people have no immunity to “new” diseases.  Conflict between indigenous people and settlers (has led to murder).  Migrants have low standard of living.

22 Towards Sustainability? Several countries are making moves towards managing rainforests more sustainably. Strategies include:  National Parks with no disturbance.  Replanting.  Involving local people in decision making.  Green and eco-tourism.  Debt for nature swaps.
