- Deforestation
- Process of which trees are cut down
- To create timber for building material etc
- To create more land for farming and buildings
- To create paper from wood
- Leads to four main problems
- More methane in the atmostphere
- Cattle produce methane
- Rearing cattle means more methane produced in the air
- Rice is grown in warm waterlogged conditions - ideal for decomposers
- These organisms produce methane, meaning more is produced
- Cattle produce methane
- More Carbon Dioxide in the atmosphere
- Carbon Dioxide is produced when burning trees to clear land
- (The carbon in wood is only seen as pollution when it is being burned)
- More carbon dioxide in the atmosphere causes global warming, which leads to climate change
- Micro-organisms feeding on bits of dead wood
- Release carbon dioxide as a waste product of respiration
- Carbon Dioxide is produced when burning trees to clear land
- Less Carbon Dioxide taken in
- Cutting down loads of trees means the amount of carbon dioxide removed from the atmosphere during photo-synthesis is reduced
- Less biodiversity (the variety of different species in a habitat - the more species, the greater the biodiversity)
- Tropical rainforests can contain a huge number of different species - when they are destroyed there is a danger of many species becoming extinct - biodiversity is reduced
- Causes lost opportunities
- E.G there are probably loads of useful products that we will never know about because the organisms that produced them have become extinct
- (Newly discovered plants and animals are a great source of new foods, new fibres for clothing and new medicines)
- E.G there are probably loads of useful products that we will never know about because the organisms that produced them have become extinct
- More methane in the atmostphere
- Process of which trees are cut down
