Biodiversity loss causes

Human activities like overpopulation, industrialization, agriculture, mining, fishing, deforestation, pollution, and exploiting biodiversity lead to habitat destruction.

Mass extinction cause

The next mass extinction is predicted to be caused by human disruption and destruction of ecosystems, not physical disasters.

Human impact on biodiversity

Human exploitation of resources and population growth is a greater threat to biodiversity than past natural disasters.

Deforestation impact

Clearing forests releases stored carbon dioxide, increasing greenhouse gases and polluting water/soil.

Study Notes

Impacts of Biodiversity Loss

  • Humans benefit greatly from biodiversity, relying on resources like water, food, and medicine.
  • Edward O. Wilson predicted a yearly loss of approximately 27,000 species, primarily due to ecosystem destruction, especially in tropical forests and grasslands.
  • Past mass extinctions were largely caused by catastrophic events, but the current threat is human-caused ecosystem disruption.
  • Population growth, industrialization, agriculture, mining, fishing, deforestation, pollution, and exploitation of biodiversity contribute to habitat destruction.
  • Introduction of exotic species, poaching, and technological advancements also harm biodiversity.
  • Deforestation accelerates biodiversity loss as it removes natural habitats.
  • Technology has both positive and negative effects on biodiversity. Clearing forests for infrastructure, agriculture, and resources releases carbon dioxide and other pollutants.
  • Biodiversity loss can contribute to climate change, pest infestations, and disease outbreaks.
  • Intensive agriculture and mining damage the environment and cause pollution and eutrophication.
  • The 14th World Congress of Public Health highlighted the link between biodiversity and human health.

Pressures on Biodiversity

  • Habitat destruction: Human activities rapidly alter ecosystems, decreasing species diversity and causing extinctions. Logging and conversion of forests are key examples.
  • Invasive alien species: Non-native species often outcompete native species for resources, impacting diversity.
  • High population density and growth rates: Increased demand for resources leads to habitat loss.
  • Climate change: Climate change is a major driver of biodiversity loss, impacting coral reefs and other ecosystems.
  • Illegal wildlife trade: The hunting of animals for profit reduces biodiversity.
  • Lack of knowledge about biodiversity: Limited public awareness hinders conservation efforts.
  • Inadequate enforcement of environmental laws: Current regulations are not always effectively enforced.
  • Failure to value the environment: The crucial services ecosystems provide (valued at $33 trillion annually) are often outside of market valuation.
