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 = IPopulation x Affluence x Technology = ImpactSimplified 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?
