(We are not counting zoos here!) For example, cacti are found in the desert, polar bears are found in the Arctic, and elephants are found in central Africa and India. These average weather conditions, such as the range of temperature and rainfall that typically occur in a particular location like Minnesota, are called the climate of that location. Plants and animals don't live in isolation, but they live together with other plants and animals in an interdependent group called an ecological community. A distinct ecological community of plants and animals living together in a particular climate is called a "biome." The locations of these different biomes across the face of Earth are shown in different colors in the map* above. Next

Tiger killing Bill Moyers Reports: Earth on Edge - Ecosystems Ecosystems are communities of interacting organisms and the physical environment in which they live. They are the combination and interaction of the plants, animals, minerals, and people in any given area of the Earth. A small bog, a single sand dune, or a tiny patch of forest is an ecosystem. But ecosystems are also forests covering thousands of kilometers, a major river system, a desert. Every centimeter of the planet is part of an ecosystem. Maybe the most familiar natural ecosystems are our backyards or parks near our home. In our heavily industrialized societies, work, religious expression, and recreation often take place in urban areas. It is our very reliance on ecosystems that is threatening them.

It is a crime fueled by a lucrative black market trade of animal parts. The animal parts are sold as novelty items and are sold for their “medicinal” properties. Environmental groups, animal rights groups, government agencies, and even the Duke of Cambridge are calling for an end to wildlife poaching. The United States Fish and Wildlife Service (USFWS), The World Wildlife Fund for Nature (WWF), and The International Anti-Poaching Foundation (IAPF) are leading international efforts to end wildlife poaching. Poachers kill for profit. Effects on Local Communities The United States is second to China in its desire for illegal wildlife parts. The extinction of a species can have a negative economic effect on a local community’s tourism industry. Effects on Animals Extinction is the greatest threat to animals that are victims of wildlife poaching. Effects on the Environment
