- Humans in the environment
- Waste production is also increasing
- Population is increasing rapidly. Resources are becoming limited.
- Deforestation
- reduces CO2 taken in and increases C02 given out
- Puts More methane in the air Untitled
- Less biodiversity. Due to habitat loss, the number of species in an area decreases, massively affecting the food chain.
- Deforestation occurs dues to :
- crops can be grown from which biofuels, based on ethanol, can be produced
- there can be increases in cattle and in rice fields to provide more food. These organisms produce methane and this has led to increases in methane in the atmosphere.
- Climate change
- Global warming increases sea level, reduces biodiversity and disrupts migration patterns
- Carbon dioxide
- When released into the atmosphere, Global warming- the trapping of light- occurs, heating up the planet.
- Stored naturally in the sea, peat bogs, green plants and fossil fuelsUntitled
- Stored naturally in the sea, peat bogs, green plants and fossil fuels
- Food production
- Fish stocks are decreasing so governments passed laws that increase the holes in nets and put in fishing quotas
- People think battery farming is inhumane, The crowded conditions encourage disease, the animals are given antibiotics which can be passed on and to keep the animals warm, fossil fuels are burnt. Untitled
- Battery faming reduces energy lost by heat to speed up the time taken for the animal to mature.
- Waste may pollute
- water
- Sewage
- Fertiliser
- Toxic chemicals
- Air
- Smoke
- Gases
- Sulphur dioxide
- Acid rain
- Sulphur dioxide
- Land
- Toxic chemicals
- Pesticides
- Herbicides
- Toxic chemicals

- BIofuels
- Biofuels can be made from natural products by fermentationUntitled
- Biogas
- Biogas, mainly methane, can be produced by anaerobic fermentation of a wide range of plant products or waste material containing carbohydrates
