| Question | Answer |
| Biomes | Large ecosystems e.g. the rain forest. |
| Biosphere | Zone where life is found. It extends 3 meters below and 30 meters above the ground, also 200 meters deep in the ocean. |
| 3 Main Climate Factors | -Temperature (most controlled factor) -Precipitation -Sunlight hours |
| Soil Health | -Leaf litter from the trees firms humus which acts as a fertilizer -Forests protect from watershed and erosion (help prevent flash floods) |
| Atmosphere | -The forest removes CO2, this is the carbon sink which helps reduce global warming -Forests produce oxygen |
| Hydrological Cycle | -Forest helps trap silt which purifies the water -Reefs and mangroves provides protection from coastal storms |
| Values Of The Biosphere | -Resources e.g. rubber from trees to make tires -Food e.g. fish and meat and fruit and nuts from trees and plants -Medicine e.g. the periwinkle plant treats leukemia and Hodgkin disease |
| -Coniferous forest are at high altitudes -Tropical rainforests are found near the equator due to high temps and heavy rainfall -decidous forest have high rainfall -Tundra are within the Artic Circle -Deserts are close to the tropics due to dry air and the suns ray concentration | |
| Direct Destruction Of The BiosphereBby Humans | -Deforestation -Mining -Quarrying -Farming -Over fishing |
| Indirect Destruction Of The Biosphere By Humans | -Pollution -Climate Change -Expanding population -Use of raw materials -Development |
| Sustainable Managment | Meeting the needs of people now and in the future and limiting harm to the environment. We need to make sure biomes are here for future generations. |
| What Does Sustainable Management Involve? | -Tree nurseries -Museums (education) -Selective logging -Eco tourism -Waterways (circle of life) -Protected areas -Afforestation (replanting) -Small scale clearance and replanting |
| Ramsar | -168 countries involved (Global scale) -Started in 1971 Protects 2.05 million km2 of wetland -Because wetland provides biodiversity in rare species -E.g. UAE and Barr Al Hikman |
| CITES | -Started in 1973 -Ensures international trade specimen of animals and plants don't threaten their survival -Because it can cause extinction -E.g. UAE, Czech Republic, Dlovakia |
| WWF | -Protects endangered animals -started in 1961 -because species are going extinct -E.g. Nepal's Himalayas and Virunga (Africa) |
| Conservation International | -Secures a stable global climate -Started in 1987 -Because the world and life is dependent on Earth's existence -E.g. Africa, Madagascar and Tonlesap Lake |
| National Parks, UK | -Protects natural beauty, 22,000 km2 in 15 parks -Started in 1951 -Because of leisure, enjoyment, culture etc. -E.g. Peak District and Yorkshire Dales |
| Forest Reserve Kilum Cameroon Republic Problems With Sustainable Managment | -Social- people may not get involved, no education -Economic- protection of endangered species costs an estimate of $31 billion, Eco tourism is low and expensive -Environmental- sustainable management means controlling the environment so biomes don't develop naturally |
