Study Notes

Biodiversity and the Healthy Society

  • Biodiversity is defined as the vast variety of life forms on Earth.
  • It encompasses all living organisms, from single-celled to multi-celled organisms.
  • This includes plants, animals, and microorganisms.

Benefits of Biodiversity

  • Biodiversity maintains the atmosphere and controls climate.
  • It controls pests naturally and pollinate crops, forming and protecting soil.
  • It provides a source for new crops and breeding.
  • Plants have therapeutic properties used in pharmaceuticals.
  • Timber, oils, lubricants, and food flavors are industrial products derived from biodiversity.
  • Parks and forests are sources of nature's beauty and joy, supporting ecotourism.

Decrease in Biodiversity

  • The World Wide Fund for Nature and Zoological Society of London report an annual decrease in wildlife by 2%.
  • Human population has doubled since 1960 to 7.4 billion.
  • This population growth has led to industrialization and habitat loss for wildlife and marine life, threatening their survival.
  • Some experts believe the Earth may be entering the 6th mass extinction.
  • Marco Lambertini has noted the unprecedented rate of wildlife disappearance.

Mass Extinction

  • Mass extinction is characterized by species disappearing at a rate faster than usual.
  • The loss of species causes an imbalance within the ecosystem, leading to more chaotic changes that harm the ecosystem as a whole.

Biodiversity and Ecosystems

  • Biodiversity is the essential source of goods and ecological services.
  • It makes up the life support system for humanity.
  • It has direct value use in food, agriculture, medicine, and industry.
  • Humans must preserve and conserve biodiversity to maintain their health and well-being.

Threats to Biodiversity

  • Habitat loss and destruction.
  • Alterations to ecosystem composition.
  • Overexploitation.
  • Pollution and contamination.
  • Global climate change.

Nutritional Impact of Biodiversity

  • Biodiversity is a vital element for a human being's nutrition.
  • It influences food production.
  • Sufficient variety of nutritious foods is essential for human health.
  • Healthy eating habits have a direct link to environmental safety
  • Some human illnesses are linked to their environment, including Parkinson's disease, heart disease, cancer, Chronic Obstructive Pulmonary Disease(COPD), asthma, diabetes, obesity, arthritis, malaria, and depression.
  • Environmental hazards like pollution, toxic chemicals, and food contaminants increase the risks of illnesses.
  • The loss of biodiversity has a direct effect on human health.

Managing Benefits and Risks

  • Managing the benefits of biodiversity and its associated environmental hazards raises social justice concerns.
  • People with lower socioeconomic status are more likely to be exposed to harmful environmental conditions.
  • Pesticides can harm human health, while energy production may have negative effects on the environment.
  • Managing biodiversity considerations may require balancing ecological benefits, environmental controls, and social justice factors.
