Doctors who are sure to help mother Earth recover fast from her illness

Mother earth is sick? Don't worry.
Earth scientists are the doctors who are sure to help mother Earth recover fast from her illness.


Your body has natural resources also

HEART - pumps blood carrying oxygen and nutrients through your body

LUNGS - to breathe in fresh air and breathe out stale air

LIVER AND KIDNEYS -to clean away toxins


All parts of your body work together
to keep you alive and healthy.

What happens if you get an infection in the
natural resources of your body?

You get sick and don't feel well.

The infection is toxic pollution
It harms your natural resources.
It harms your body's environment.

Then you need a special investigator to find out what is making you sick and to help you get well.

Your body's special investigator is your doctor.

The doctor can tell you what medicine to take to get rid of the toxic infection, so your body can get healthy again.

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
