Tropical Rainforests - adaptation of species. Explain why the rainforest is an important natural resource.

Extracts from this document...

Introduction

Tropical Rainforests Because the Climate of the rainforest is hot and wet all year round, plants and animals have had to adapt to the extreme climate. Adaptation Reason Very tall trees (emergent's) In the rainforest an emergent can grow up to 40 metres! Trees grow high in the rainforest because of the climate they are in. This is hot weather with strong sunlight with lots of rain. It is important for trees to grow high because they're in competition with other trees and plants for light and water. If a plant doesn't grow high then it won't have as much light and water as the sheltered plants, therefore they need to adapt to grow tall in order to survive. The reason they need to grow high is so that they can get water (via interception) UV light from the sun and heat. All these factors help it photosynthesis. Tree trunks are straight and branchless Tree trunks are straight and branchless in the rainforest because, so that they can grow tall. As their efforts can be on growing tall not having branches near the bottom. More water falls down on the top of the tree. Therefore they put their efforts in growing tall so that gain most water. Not as much water falls near to the bottom of the tree therefore there is no need to have branches. ...read more.

Advantages of this are that they get food; disadvantages would be that you don't get any luxuries in life, as you are poor. This is sustainable, because they get just enough, and don't pollute the atmosphere. Commercial Farming is the farming which is performed on large scale, with the help of machine like harvesters and tractors etc. This is becoming ever more popular in the rainforests of today as demand for food grows rapidly, an advantage is that they get lots of money, a disadvantage of this is it non-eco friendly, because they need petrol etc to power machines. This is unsustainable as it uses non renewable energy sources . Logging is where the cutting of trees in a forest for timber. Logging is the process of which certain trees are cut down by a machine for forest management and timber. This is a major cause of deforestation as they're cutting alot of trees down, this is unsustainable because it destroys trees, and this is a disadvantage, an advantage would be that they earn a living. Mining/ oil exploitation is also a major factor why the rainforest is being destroyed. This is where large quantities of oil are brought up from the ground. This can also lead to trees being destroyed; because they need large areas of straight/flat land, this will end up killing trees and wildlife. ...read more.

Conclusion

Resulting, in him trying to create public transport and other unsustainable transport in the rainforest. This is so he can make most money for Brazil. However, the Environmental minister would be more sympathetic to the rainforests. He would also want to preserve the rainforests. This is because his job is to make Brazil one of the most environmental friendly countries in the world. Furniture manufacturers in Britain use the rainforest for importing wood. They use it to make Furniture, and then sell it to make money. Tourists use the rainforest to look at animals in safaris. Their view on the rainforest could be very mixed. For example a majority of them would want Hotels and transport, which would destroy the natural beauty. However, some may like it primitive. Residents would use the rainforests for homing. 4.) Consider whether there are ways that the resources of the Amazon Rainforest can be both exploited and conserved so that the forest can be used in a sustainable way. The rainforest can be both exploited and conserved. If we allow loggers to cut down there trees, then we could equally combat the problem by planting more trees. Or get the logger to plant a tree seed in replacement of the tree he has just cut down! So yes we can however, we would have to invest a lot of money in the scheme to get lots of people planting seeds. ...read more.
