Clearing of trees, transforms forests into plains
1 of 17
Uncovered in deforestation, fossil fuel like ethanol in swamps
2 of 17
Variety of species making an ecosystem
3 of 17
Increasing population (People)
More housing, mining in large areas, more food and farmland, creates waste and needs to be stored
4 of 17
Increasing population (Resources)
Need more raw material, fossils fuels will run out and will pollute the Earth
5 of 17
Increasing population (Water)
Waste in the water like sewage, contaminates water. Use indicator species like Mayfly indicates clean and snail means dirty
6 of 17
Increasing population (Air)
To provide energy more fuels used like burning coal and oil, increases pollution
7 of 17
Greenhouse effect
Sunlight hits Earth and reflects, CO2 in atmosphere trap heat and warm the Earth from fossil fuels
8 of 17
Effects of Global Warming
Migration changes, species distribution change due to heat and loss of habitat due to flooding
9 of 17
Preventing Global Warming
Nuclear power, renewable energy sources, Kyoto agreement reduces CO2 levels
10 of 17
Methods of conservation
Breeding programmes, Protection, reduce deforestation, recycling
11 of 17
Sustainable, Mycoprotein= protein made of fungi, cheap, contains little fat, produces biomass from food faster than any animal
12 of 17
Oxygen for respiration, mix microorganisms evenly to keep temperature even. Or genetically modified bacteria to increase growth
13 of 17
Intensive Farming
The manner to obtain maximum yield when farming, can increase production by antibiotics and temperature or decrease food chain to keep the most energy
14 of 17
Threat to biodiversity
Unsustainable fisheries and increased pollution, ecosystems could degrade and destroyed
15 of 17
Depleting fish population
Over-fishing, pollution, disrupting habitats
16 of 17
Preserving fish populations
Fish farms (controlled farms with high protein so less fish needed), Fishing quotas (certain amount of fish caught)
