ENVIRONMENTAL PRINCIPLES : ENVIRONMENTAL PRINCIPLES Slide 2: As defined by the Asian Development Bank, is a process by which people develop awareness, concern and knowledge of the environment and its diverse values and processes, and learn to use this understanding to preserve, conserve and utilize the environment in a sustainable manner for the benefit of present and future generations. Environmental Education 1.Interdependence/Interrelatedness : 1.Interdependence/Interrelatedness Biotic and abiotic components are equally important in the ecosystem
Example is the relationship between autotrophs and heterotrophs 2. Diversity and Sustainability : 2. Diversity and Sustainability Diverse community is a stable community.
The more species present, the more stable the community because several species keep other species in check, preventing any species from overpopulating the habitat. 3. Change : 3. Change It is the constant thing on Earth.
Ecosystem change over time and space.
Any change in the community affects the different organisms within it.
Ex: Natural change and Human-induced changes 4. Balance of Nature : 4. Balance of Nature Ecosystems are capable of self-maintenance and self-regulation. Ex: Predation
Limited resources check population densities. 5. Finiteness of Resources : 5. Finiteness of Resources It means that there are limitations and boundaries to utilization.
Even the most abundant natural resources are in danger of being depleted in the light of human overpopulation and overexploitation.
Ex. Fossil fuels bec. of industrialization and domestic consumption,
some species because of habitat destruction, overhunting and excessive harvesting
Potable water bec. of drought 6. Pollution : 6. Pollution It is the undesirable accumulation of substances resulting in diminished quantity and quality of a resource.
Ex. Air pollution-continuous increase in temp and climatic patterns,
water pollution- dumping grounds of various domestic and industrial waste
and soil pollution- soil is degraded through soil erosion, siltation, sedimentation of rivers,lakes, streams 7. Stewardship of resources : 7. Stewardship of resources It means efficient management by maintaining a balance between population growth and resource use.
It is not an act of a good steward to overexploit the borrowed resources 8. Sustainability : 8. Sustainability Actions that address the needs of the present without compromising the needs of the future generations to meet their own needs are embodied in the concept of sustainable development.
Concerned with socioeconomic dev’t (human) and environmental quality.
