Laws of Nature

Laws of Nature. The Law of Gravity. Gravity is a force of attraction between objects that pulls all objects on earth towards the center of the earth at a rate of 9.8 m/sec Environmental Application Our Freshwater and pollution go to the same place; rivers, lakes, aquifers, the lowest point.

  1. Laws of Nature

  2. The Law of Gravity Gravity is a force of attraction between objects that pulls all objects on earth towards the center of the earth at a rate of 9.8 m/sec Environmental Application Our Freshwater and pollution go to the same place; rivers, lakes, aquifers, the lowest point

  3. The Law of Matter Matter can neither be created or destroyed. Environmental Application Once pollution is created it is very difficult to clean up because you have to have some way to rearrange the atoms, it won’t just disappear.

  4. The First Law of Energy Energy can neither be created nor destroyed. Environmental Application We can’t just magically make energy. Virtually all energy sources on earth originate from the sun.

  5. The Second Law of Energy Whenever energy is transferred some (on average about 90%) is lost as low quality heat energy. Environmental Application Since we are so lousy at transferring energy we consume a supply of energy approximately 10 times greater than we actually use to do the work necessary to stay alive.

  6. Competitive Exclusion Principle No two species can occupy the same niche. When a new specie is introduced to an already occupied niche, one of the following options will occur. One or both species adapt to a new niche (usually takes thousands to millions of years) One Species migrates to find a new unoccupied habitat and niche One of the species goes (locally) extinct.

  7. Competitive Exclusion Principle Environmental Application Invasive species put enormous pressure on native species. Modern day human civilization has created the greatest impact. Fragmenting most areas leaving native species to live in almost inhabitable environments. Eventually leading to extinction.

  8. The Law of Sustainability Systems that are sustainable depend on an endless supply of renewable energy and efficient recycling of the matter they needed for growth and development. Environmental Application: Stable, sustainable systems follow these rules of nature or the system breaks down.

  9. Characteristics of Natural Systems Sustainable for Hundreds, Thousands, and millions of Years

  10. Species have evolved adaptations to compensate for the effects of Gravity in their environment Species have evolved ways to effectively transfer matter and energy between the living and non-living portions of ecosystems (Symbiosis).

  11. The greater the number of interactions between species, the more effective the transfer of matter and energy in an ecosystem over a long period of time. Biodiversity results from billions of years of cooperation and competition between species for the matter and energy they need to survive When the transfer of matter and energy are severely interrupted, the loss of biodiversity occurs
