Study Notes

Environmental Balance

  • Environment is formed by biotic (living) and abiotic (non-living) components
  • Biotic components include plants and animals; abiotic components include solar energy, air, water, soil, landforms, and rocks
  • Living components interact with non-living components in an ecosystem
  • Environmental balance relies on these interactions
  • "Bio-community" encompasses all living organisms on Earth
  • Environmental balance involves maintaining the environment where the bio-community lives, while protecting environmental attributes despite natural changes

Importance of Maintaining Environmental Balance

  • Environmental balance involves interactions between living beings and their physical environment, with humans also considered a vital component.
  • Activities of living beings mutually impact each other and environment; maintaining this balance is crucial
  • Humans depend on the environment for basic needs, transportation, and other needs

Factors Causing Collapse of Environmental Balance

  • Increased human population and modern technology needs accelerate the demand on environmental resources beyond the environment's capacity.
  • Traditional agricultural practices had a minimal impact on the environment, but industrial revolution intensified negative impacts
  • Excessive waste generation and damage to environmental components resulted in environmental imbalance
  • Factors contributing to environmental imbalance include excessive resource use, irregular development, fossil fuel burning, agro-chemical use, deforestation, land reclamation, and inappropriate technology use

Unfavorable Effects of Collapsing Environmental Balance

  • Environmental collapse poses a severe crisis for the Earth, potentially rendering it uninhabitable for life within 200 years.
  • Human activities primarily drive environmental problems, necessitating worldwide cooperation for solutions

Human Activities Affecting the Environment

  • Forest destruction
  • Flora and fauna destruction
  • Water source destruction
  • Agro-chemical use leading to soil and aquatic life destruction, water contamination
  • Fossil fuel use causing air pollution and temperature increase
  • Improper urbanization leading to waste generation, blocking waterways.
  • Improper waste disposal causing health hazards and beauty loss
  • Military weapon experimentation causing atmospheric and water pollution

Environmental Ethics

  • Environmental ethics are principles guiding environmentally responsible human behavior
  • Ancient cultures often showed respect for nature linked to beliefs and religions which helped maintain the environment.
  • Environmental ethics are important in the quest for sustainable development
  • All religions support the importance of environmental protection

Sustainable Development

  • Sustainable development satisfies current needs without compromising future generations' needs.
  • This needs careful consideration of environmental ethics in development plans
  • Both development and environmental protection are essential in achieving sustainable development

National and International Procedures to Protect Environmental Balance

  • Various national and international procedures/conventions exist to protect environmental balance.
  • Examples Include land-use planning, wildlife and forest conservation, sustainable agriculture, coastal conservation, environmental education, and the establishment of environmental authorities (e.g., Central Environmental Authority in Sri Lanka).
  • International examples include the Ramsar Convention on wetlands and the Montreal Protocol on ozone layer protection.
  • Sustainable development provides guidance about how to utilize resources while securing the environment for future generations
