Earth's natural resources need
to stay healthy too!
WATER
To
clean the atmosphere and the environment,
and to nourish plants and animals |
SOIL
To filter the water, provide nourishment for
plants and some animals,
and recycle material to be used again |
PLANTS AND TREES
To absorb carbon from the atmosphere and
release oxygen.
To supply food and medicine, and provide shelter for plants and animals |
ATMOSPHERE
Air surrounding the planet containing
nitrogen, oxygen, water vapor, other gases, and many tiny particles
To protect life on the planet, shielding it from harmful radiation from the sun.
To provide a blanket of warmth around the planet
The atmosphere is being damaged by carbon
dioxide overload,
so more harmful radiation is reaching us on Earth -
and the blanket of warmth is getting warmer! |
What happens when pollution
gets in Earth's natural resources?
They become impure and poisonous,
and then plants and animals get sick.
Toxics and pollution harm the Earth's environments,
just like they harm our bodies.
The Earth's doctors are the Earth
Scientists.
They investigated the environments' illnesses
and said:
|
POLLUTION OF AIR, WATERS AND SOIL
CLEAR-CUTTING FORESTS
DUMPING TOXIC WASTE
CUTTING OLD-GROWTH TREES
HARMFUL FISHING METHODS
DEPLETING AND WASTING NATURAL RESOURCES
DESTRUCTION OF OZONE LAYER
DESTRUCTION OF BIOLOGICAL DIVERSITY
EXTINCTION OF SPECIES |
REMEMBER TO
REDUCE - REUSE - RECYCLE
AND SAVE ENERGY
IS THE SUN A RENEWABLE RESOURCE?
We received this question from a student who presents a very good point
for debate on the subject.
"Hi,
I am doing a paper on non-renewable and renewable resources.
All the information I have found says that the sun is a
renewable resource. I disagree with this because in
science class we learned that the sun is a star.
Therefore, it has a lifespan. That is why it can explode!
So if it can explode and not be able to be used again, how can
it be a renewable resource?" |

All of our natural resources are essential
in helping to keep the Earth's natural processes in balance
in order to
provide a life-sustaining environment.

Now that you have absorbed
all that information,
we're going to take a trip around our
planet
and give it a health checkup.
We'll do some investigation, like doctors
and scientists do,
and look at the Earth's environments and the plants and animals.
On this trip you will go exploring, join
in activities,
and do science projects
while you learn about plants, animals,
our Earth, and the universe.
You will meet people who are helping save the natural
environment.
Are you ready to go on our exciting
journey?
