To Students Everywhere:

Today, we all know what Earth looks like from a distance. Our ancestors never got to see the• "big picture" of Earth. Instead, they viewed the planet as a huge unknown, with unlimited resources. We know that Earth is a single, small globe floating in space with limited resources.

We must protect our environment and the resources we share in every way we can. We - all of the inhabitants of planet Earth - must work together to make the environment as clean and healthy as possible.

The key to protecting the environment is action. We can all take responsible action to make this a better world - a world that stops pollution and ends wasteful use of natural resources, a world that respects and preserves our animal and plant kingdoms, a world t-hat is a healthier and happier place to live.

Ecology

The ecological problem is the most urgent one concerning the people of the whole world.
