Are Animals Worth It?

Thirty years ago, congress passed a law to protect animals that are at risk of becoming extinct. The Endangered Species Act of 1973 outlined the responsibilities of the government and citizens concerning these animals. It requires that every five years, species are evaluated, and it is decided whether they are okay, endangered, whose population is so low that it is in danger of becoming extinct, or threatened, who are not in as much danger, but whose population is small enough for concern. Threatened and endangered species are then placed on a list, the “red list,” and closely monitored until conditions improve and population numbers increase enough that they can be removed. But how are these animals

One big advantage to in vitro fertilization is that it enables scientist to keep genetic variability in these species by uniting genes from animals separated by great distances. Too much inbreeding, mating of related animals, does not provide the genetic diversity these species need to survive (Begley 12). Scientists believe that inbreeding is the cause of the dwindling of many species, such as the precious pandas, as well as the rhinoceros. Zoos have also been trying to release some of these animals back into their habitat, in order to do so these animals must have a complete, yet diverse, set of genes to ensure their survival against diseases and predators. Technology has enabled this process to be very successful.
Inbreeding is a major concern for conservationists in trying to successfully increase population numbers of endangered species. Before, scientists had no way of determining the genetic variation of any animals, resulting in inbreeding. They now have the science to determine how related to animals are, and can determine which animals to bring together in the laboratory. Though, this means disrupting natural behavior, it seems worth the while. It gives every male and female the chance to reproduce, when otherwise they may not have been able to. This means that scientists can control the increase in population by accelerating the process (Begley 13). In vitro fertilization has proved
