- Human population growth
- Increased reliance
and need of non-renewable energy which drains natural resources
- More greenhouse gases
released into the atmosphere
- global climatic
change due to the increase of the Earth’s overall atmospheric temperature
- Changes in climate = more natural disasters
- Rising sea levels = flooding
- Changes in migration patterns and distribution of animals
- Affects the carbon
cycle and eco-system = reduction in biodiversity
- Can kill leaves, destroy roots and acidify open water sources which if too high can kill organisms living in it
- global climatic
change due to the increase of the Earth’s overall atmospheric temperature
- More greenhouse gases
released into the atmosphere
- More animal habitats are being destroyed to make
more land for building, quarrying, farming and dumping waste
- less trees = less photosynthesis which helps to remove carbon dioxide from atmosphere
- global climatic
change due to the increase of the Earth’s overall atmospheric temperature
- Changes in climate = more natural disasters
- Rising sea levels = flooding
- Changes in migration patterns and distribution of animals
- Affects the carbon
cycle and eco-system = reduction in biodiversity
- Can kill leaves, destroy roots and acidify open water sources which if too high can kill organisms living in it
- global climatic
change due to the increase of the Earth’s overall atmospheric temperature
- This leads to the destruction of plant and
animals – extinction
- reduced the rate at which carbon dioxide is removed from the atmosphere and ‘locked up’ for many years as wood
- less trees = less photosynthesis which helps to remove carbon dioxide from atmosphere
- Increased amount of
waste such as industrial waste
- Water pollution: sewage, fertilisers and toxic chemicals (industries/factories)
- Air pollution: smoke
and gas containing sulphur dioxide
- ACID RAIN: Dissolves in rain water and reacts with oxygen to produce dilute sulphuric and nitric acid
- Particulates which reflect light = Global Dimming
- Leads to cooling of the temperature of the Earth's surface
- ACID RAIN: Dissolves in rain water and reacts with oxygen to produce dilute sulphuric and nitric acid
- Land pollution: with
toxic chemicals such as pesticides and herbicides
- May be washed from the land into waterways
- Water pollution: sewage, fertilisers and toxic chemicals (industries/factories)
- EUTROPHICATION: Nitrates and other minerals from untreated sewage or fertilisers leads to rapid growth in vegetation in water (more competition for light)
- Lots of plants die = increase in microorganisms feeding = fall in oxygen levels dissolved in water
- Leads to insufficient oxygen for plants and fish in water which die and are decomposed by more microorganisms
- Eventually oxygen levels are so low that all aquatic animals dies
- Leads to insufficient oxygen for plants and fish in water which die and are decomposed by more microorganisms
- Lots of plants die = increase in microorganisms feeding = fall in oxygen levels dissolved in water
- May be washed from the land into waterways
- Destruction of peat bogs and other areas of
peat releases carbon dioxide
- More greenhouse gases
released into the atmosphere
- More greenhouse gases
released into the atmosphere
- Increased demand for food = farmers using for fertilisers and pesticides
- Increased reliance
and need of non-renewable energy which drains natural resources
