Protecting Yellowstone is the responsibility of the American public. The World Conservation Union recently listed the 2000 edition of its Red List of Endangered Species. The last previous listing was in 1996. An even more startling conclusion of the report is that the current extinction rate is 1000 to 10,000 times higher than what it should be under natural conditions. The growing expansion of cities, deforestation, agriculture and fishing are some of the main human activities that are contributing to the phenomenal rate of plant and animal extinction.
