Diminishment of Ecosystem:

Many human activities have side effects on the functions of ecosystems and cause their diminishment.

  • Mining and deforestation lead to habitat destruction and disrupt the balance between living and non-living components.
  • Overfarming and urbanisation reduce biodiversity and degrade soil quality.
  • Pollution from industries and waste contaminates air, water, and soil, harming plants and animals.
  • Overfishing and hunting threaten species and disrupt food chains.
  • Climate change caused by human activities alters ecosystems and forces species to adapt, migrate, or face extinction.
  • The introduction of invasive species by humans harms native plants and animals.
  • Construction and infrastructure development fragment habitats, reducing space for wildlife.

Diminishment of Ecosystem

Maharashtra State Board: Class 8

Human Interference:

  1. Resource Overuse: Rapid population growth and changing lifestyles deplete natural resources, creating waste and putting pressure on ecosystems.
  2. Urbanisation: The expansion of cities destroys agricultural lands, wetlands, and forests, leading to the loss or transformation of ecosystems.
  3. Industrialisation and Traffic: Forests are cut down for raw materials, and infrastructure like roads disrupts habitats and wildlife.
  4. Tourism: Facilities for tourists damage ecosystems, especially in scenic and sacred areas, due to increased human activity.
  5. Large Dams: Dams convert land ecosystems into aquatic ones and disrupt water flow, harming downstream ecosystems.
  6. Wars: Bombing and land exploitation during wars destroy ecosystems and alter natural landscapes permanently.
