All these efforts are straining the limits of the Earth’s “carrying capacity”— its ability to provide the resources required to sustain life while retaining the capacity to regenerate and remain viable.
•incalculable technological achievements
•population growth
•corresponding increases in resource use
Since the Industrial Revolution the world
has witnessed
pollution landfills toxic waste global warmingResourcedepletion
ozone depletion deforestation
SIDE EFFECTS ARE
INDOOR AIR CONCERNS
Most people spend at least half of their
lives indoors.
Indoor air can be more harmful than
outdoor air.
Poor indoor air quality can cause
respiratory problems.
Poor indoor air quality can be more
harmful for children .
insufficient fresh outdoor air entering a ventilation
system are often the direct result of overzealous
energy-saving procedures.
