Issue 1 - TREE TOP INSECTS
Scientists have always known that tropical rain forests have more biodiversity than many other places on Earth; but they were still very surprised by what Terry Erwin found during his study of the forest canopy. Using calculated projections, he determined that there were up to 30 million creatures living in the tropical forest. That's much more than the 2 million previously thought to exist! In this issue, we learn about the various methods used by scientists to study the biodiversity in the forest canopy. - 12 Minutes

Issue 2 - GIVING BACK THE LAND
In the early nineteen hundreds, the practice of strip mining to supply minerals to manufacturing industries left land in many parts of the world barren, scarred an unable to sustain life. Now science is finding ways to correct the ecological mistakes of the past. This program looks at experiments in land reclamation, including bioremediation trials that use plants and bacteria to restore the terrain. - 14 Minutes

Issue 3 - OUR GREEN PLANET
This issue explores how plants moved from the sea to land after developing a vascular system to transport water, minerals and food throughout the plant. It discusses how the plants and trees we know developed over time, explains the process of photosynthesis, and the unique ways some plants and trees have adapted in order to survive in difficult conditions. - 15 Minutes

Issue 4 - THE IMPORTANCE OF BIODIVERSITY
This issue explains why some scientists warn that maintaining a variety of life forms on our planet may be crucial to the survival of the entire web of life on Earth. This issue visits an environmental research facility, the world's largest specimen collection, and follows researchers conducting biodiversity studies in a rain forest as well as on a coral reef. - 15 Minutes

Issue 5 - SAVING EARTH'S ANIMALS
One of the greatest challenges of the 21st century will be the preservation of biodiversity. This issue explores the future of wild animals, and the efforts scientists and conservationists are making to protect the over 5,000 species that are currently living under threat of extinction. Students will learn that our animals and plants are vital parts of our biosphere that must be preserved. - 12 Minutes
