Problems/Solutions


You’ve just been to Wal-Mart. Rather
than throw away your bag, you
decide to reuse it.
Brainstorm a list of ways to reuse the
bag.
Environmental Problems

Habitat Destruction
Pollution

What do you think of when you think
of pollution? Which type of pollution
do you think is worse?
Types of Pollution

Solid Wastes

Chemicals

Radioactive Wastes

Gases
Solid Wastes
Hazardous Wastes
Waste that can catch fire, wear
through metal, explode or make
people sick
Chemicals

Compare/contrast CFCs PCBs
Nonrenewable/Renewable
Resources


Renewable Resource: a natural
resource that can be replaced at the
same rate at which the resource is
consumed
Nonrenewable Resource: a
resource that forms at a rate that is
much slower than the rate at which it
is consumed

Renewable vs. Nonrenewable

Are there any items on the
renewable list that could become
nonrenewable?
Renewable

Many renewable resources could
become so polluted or overused that
they would no longer be valuable.
Human Population Growth



The human population exhibits
exponential growth.
As more people move around, more
natural resourced are needed.
Eventually, the resources may
become depleted and pollution level
may rise.
biodiversity

Deforestation, point-source, nonpoint sources
Your Community


Draw a picture of what your
commmunity might look like in the
year 2100 if pollution and habitat
destruction continue at a rapid rate.
Draw a picture on the other side
showing what it looks like if the
environmental problems are
prevented
Prevention of Environmental
Problems



REDUCE
REUSE
RECYCLE
