Preserving the tropical rainforest ecosystem, especially through public education, will help improve the environment worldwide and yield improvements in science.If asking a zoologist to describe the rainforest, he would say that the rainforests contain millions of undiscovered species of animals. Most of the animals have developed ingenious ways to protect themselves. Some have developed camouflage to blend into their surroundings, making them invisible to predators. Other animals use mimicry, which is the imitation of more threatening animals to keep their enemies away. All of the animals exist in a delicate food chain; forcing one animal into extinction will damage other species of animals higher on the food chain that depend on the lower animals for food.An anthropologist would tell say that the rainforest is home to very old human cultures. By removing the trees, we are destroying these cultures and their traditions. These people, even though primitive, have even more extensive knowledge of the healing powers of plants than modern medicine. The indigenous cultures in these forests are also able to teach us how to use the resources without destroying them; they have been doing such things for centuries.A botanist would also talk about the wonderful properties of plants, but will also tell you how diverse plant species really are in the tropical rainforest. The botanist would talk about the canopy, under story, and forest floor. The canopy is the highest point in the tropical rainforest and receives the bulk of the sunlight. It is the center of most of the activity in the rainforest. The under story receives even less light than the canopy, and many plants climb up the trees to reach the sunlight to survive. The forest floor is very dense with plants. When a tree falls, sunlight is allowed to shine through, sprouting dormant seeds on the forest floor. The new seedling will become a tree, replacing the fallen tree; the fallen tree will be recycled into nutrients by bacteria for reuse by other plants, thus completing a delicate cycle that has continued for centuries.The tropical forests hold vast possibilities for new foods. Everyone is familiar with foods from the rainforest already, even if they do not know it. Coffee, bananas, vanilla, tomatoes, peanuts, cinnamon, cacao, manioc (tapioca), and many others come from the rainforest. Most of the fruits and vegetables in the produce section have had their origins in the tropical rainforest. New foods are always being introduced, like the guava or naranjillo. Deforestation threatens new discoveries and threatens the possibility for better strains of vegetables that are already familiar. Germ plasma, which was once used to domesticate fruits and vegetables, can be used again to improve crop strains and pass on resistance to diseases.As the rainforests disappear, so are some of the possible cures for diseases. Rainforest people have shown us many of the medically important drugs in use today in their...
