Resource Conservation

  • Conservation is the protection and rational use of the environment and natural resources to ensure they are there for future generations
  • This involves measures which use resources efficiently to extend their existence for as long as possible 
  • Conservation measures include;
    • Recycling and reuse of resources such as clothing or glass and plastics
    • Using energy efficient appliances - these use less energy to power them and less water
    • Stewardship of protected areas - National Parks, Areas of Outstanding Natural Beauty (AONB)
    • Greater use of, and investment in renewable energies
    • Quotas on resources used - rising quotas to ensure the fish population is not overfished
    • Protection of particular ecosystems - Sites of Special Scientific Interest (SSSI) and the Antarctica Treaty which includes agreements about the exploitation of Antarctica
    • Reducing deforestation
    • Laws to protect resources and areas
    • Fines for people/organisatiions/companies that damage the environment 
    • Reducing use of or rationing of resources
  • There are many non-governmental organisations (NGOs) which aim to conserve and protect the environment and natural resources;
    • World Wildlife Fund
    • Greenpeace
    • Friends of the Earth
    • Woodland Trust
Government Actions Individual Actions
Congestion charges within cities  Use public transport
Investment in renewable energy Walk or cycle
Grants for solar panels Reduce, reuse and recycle
Gas emission limits for vehicles Buy energy efficient appliances
Charging points for electric vehicles Invest in double glazing and insulation
Increase tax on petrol and diesel Wash clothes less often and at lower temperatures
Invest in public transport Compost food and garden waste
Fines for businesses and industries which pollute  

Worked example

Study Fig 1, which shows advice about conservation of natural resources.

Explain how following the advice given in Fig 1 can help to conserve natural resources.

[3]

  • Answer:
    • Uses fewer resources/less demand for resources or example/there are fewer resources wasted [1]
    • Saves resources for the future [1]
    • Can use resources again/make more use [1]
    • Resources last longer [1]
    • Saves energy [1]
    • Waste products become useful [1]

Explain the importance of conserving natural resources and the natural environment.

[5]

  • Answer:
    • Many are non-renewable/will run out/are finite [1]
    • Life in future would not be possible without clean water [1]
    • Life in future would not be possible without clean air [1]
    • Life in future would not be possible without land for cultivation [1]
    • To protect habitats [1]
    • Conserving the natural environment will ensure ecosystems remain in balance [1]
    • Species do not become extinct/animals do not die [1]
    • To prevent global warming/acid rain/desertification etc. [1]
    • Creates conflict/civil rest [1]
    • Forests act as carbon sinks [1]

Example Case Study: Pearl River Delta, China

  • Located in South-East China, the Pearl River is China's third longest river
  • The Pearl River enters the South China Sea to the south-east of Guangzhou
  • The area surrounding where the river enters the sea is the Pearl River Delta

location-of-pearl-river-delta

  • The area is China's largest economic hub, creating over 9% of China's total GDP
  • It is the largest urban area or megacity in the world
  • Over 60 million people live in the region

Pollution sources

  • Air pollution from power plants - there are both gas and coal fired power stations in the region which emit sulphur dioxide, carbon dioxide and nitrogen oxides
    • Emissions lead to smog, acid rain and add to enhanced greenhouse effect
  • Toxic waste from factories and sewage from large population released into the rivers

Impacts of pollution

  • The Pearl River Delta has the highest level of acid rain in China
    • Leads to acidified groundwater
    • Increases heavy metals found in crops and drinking water
      • Linked to increased rates of stomach cancer
  • Increase in heavy metals in river water and river sediments including lead, zinc, chromium, copper, arsenic and mercury
    • All harmful to humans and wildlife when in absorbed sufficient quantities
    • Heavy metals pass through the food chain 
    • Rice cultivated in the area has been shown to be contaminated with arsenic and this poses a health risk to the people who consume it
  • Pesticides affect wildlife and accumulate in the food chain impacting human health
  • Fertilisers lead to eutrophication
