Earth's Report Card for 2000 (4/18/00)
Date of this Version
With Earth Day on the horizon, we examine the condition of our planet's health. We'll do a checkup on the atmosphere, the plants and animals, the oceans, the underground water tables, and all the other vital signs that contribute to the well being of our Mother Earth. Can she pass the tests and make the grade? Have we made any progress since the birth of the ecological movement in the 1960's?
