Pollution, Waste, Energy Efficiency

What is Pollution?? DEF: Any addition to air, water, soil or food that threatens the health, survival, or activities of humans or any other living organisms. Natural or Man-Made Solid, liquid or gas = by-products or wastes 2 Sources Point Source –single identifiable source. Ex) Tailpipe, Drainpipe, Power plant Easier & Cheaper to ID Non-Point Source – dispersed, difficult to ID Ex) Spray or Runoff from farms, golf courses

Different Types of Pollution

AIR POLLUTION Global Climate Change? Stratospheric Ozone Depletion Urban Air Pollution Acid Deposition Outdoor Pollutants Indoor Pollutants Noise

Temperature Inversion traps pollution

Air Pollution Affects You!!

WATER &/or LAND POLLUTANTS Sediment & Runoff Nutrient Overloads/Algal Blooms Toxic Chemicals Infectious Agents Pesticides/Herbicides Oil Spills Excess Heat

Spraying Chemicals (non-organic)

If pollution affects the food chain then it affects YOU!!!

WASTE PRODUCTION SOLID WASTE –landfills, sewage HAZARDOUS WASTE Nuclear Waste

Landfill Site

Water & Sewage Treatment Plant

How do we live more sustainably?? FIND the BALANCE-make a change? Do OUR Part- stewardship for Earth Educate-tell a friend

P x A x T = I Population x Affluence x Technology = Impact Simplified model of three factors that equate the damage we do on Earth The number of people there are (P), multiplied by the amount of resources each person uses (A), multiplied by the amount of degradation (pollution & environmental waste) per unit resource equals environmental impact of population

Of Course Best Options: Prevent Pollution Management/Plan Reduce Reuse Recycle Do without

Laws that help protect us

Placards

Should we depend on Gov’t?

Which of our Energy Types would you choose? EVALUATE!! Non-Renewable or Renewable? Which had less Pollution/Waste? Which was most Efficient? Go to:
