Transcript When Man Destroys Nature Man is Actually Destroying Himself
When Man Destroys Nature Man is Actually Destroying Himself Biodiversity is important – losing species hurts our species Matter and Energy are Indestructible, but can be readily transformed to less desirable, unusable, and even harmful forms Two Laws of Thermodynamics Car examples!!!!!!! Man is Stupid Just about everything we talk about Resource Uses, Regulations and Management Practices that do not Consider the Future are Nothing Nonrenewable resource use that doesn’t take into account the actual cost of the production Pyramids of Consumption Lead to Increased Concentrations of Matter WASTE!!!!!!!!!!!!!!!!! Man Must Change His Role as Conqueror of the Earth and All that it contains to that of a Responsible Citizen that takes his place among the order of things Global Warming, Ozone Depletion, Acid deposition Man-made Monocultures and Simple Natural Vegetation types are Commonly Subject to Natural Catastrophes Destroying biodiversity causes a collapse of ecosystems Keystone Predators The Introduction of Alien Species or Substances is to be Avoided and if Must be done, It should be with Extreme Caution and when there are no Alternatives Endemic Species get pushed out Diversity = Stability Keystone species Natural Resources are the Basis of Economic and Monetary Systems and Systems that Expand Beyond this Resource Base must Ultimately Collapse Gas Prices!!!!!!!!!!!!! Summer vs. Winter Gas Man obtains Energy from Either Renewable or Nonrenewable Sources or Supplies Be able to tell the difference between the two types Which are which? The energy in must equal the energy out Conservation of Matter Resources are either renewable or nonrenewable and must be treated accordingly Where is our long term future???? What are we willing to pay??? The most precious natural resource is life starting with human life and including the equally important diversity of all living things inhabiting the earth Biodiversity is important – losing species hurts our species Conserving Energy and Resources not only saves resources but also helps to protect the environment from which the resources/energy are obtained and the environment in which people live The best way to protect the environment from hazardous waste is to prevent the production of it. A Healthy and Stable Economy and a Healthy Environment are Inseparable Goals Politics!!!!!!!!!!!!!
