Wild species, which includes that of animals, plants, and of other organisms, constitute the most part of the seafood of the world and of the timber. The Wild species provide a means of earning to the communities apart from providing them with food, medicines, fibers, skins, furs and forage, without which many communities could not have had their living.
Apart from this they also help in the intellectual growth, provide a sense of beauty and also promotes the religious and cultural beliefs of the people. Because of the importance given to the wild species and of the use made of them by people, many natural and semi-natural ecosystems owe their present existence and even their future would owe to these uses.
Firstly, the use of wild species is that it has direct commercial value in terms of fishing, hunting, harvesting which enables the U.S. economy to earn $200 billion and also the commercial value could be witnessed in terms of the legal trade of exotic species, which includes that of birds, aquarium, and reptiles. Secondly, wild species have many traits and so have their potential use. Drought resistance, parasite resistance, salt tolerance, disease resistance, tolerance of extreme heat, cold, etc., need wild species as a source of genetic material. This is for the purpose of breeding or genetic engineering in existing crops/animals, pest control, for useful products, which are still not, recovered, and those which could become potential new crops. Thirdly the use of wild species has their medicinal value- for several decades, in the United States of all the prescriptions written contain chemicals, which are discovered in plants and animals. Fourthly, its usage is of enormous recreational value-, which is very often an important part of the revenue of the local economies. The revenues are earned by means of eco-tourism, sport hunting, and bird watching. They also have their aesthetic importance, which is the source of inspiration for poetry, art and so on.

Next, killing of the other forms of life is not only morally wrong, but also dangerous, since that can never be replaced. Since humans are being used to diversity of various forms of life, the quality of mankind would be reduced, if the diversity in nature does not exist any more. Hence the wild species have an intrinsic value. Ecosystems compose the earth's biosphere. And the ecosystems comprises of animals, plants and their physical environment. And no living creature can exist in a vacuum, since all living creatures are part of the biosphere, which is a network of delicate balance and complexity. If a single species is removed from an ecosystem, then it can affect other species as well resulting in a chain reaction. It has been found that when a plant disappears it would make 30 other species, which includes higher animals, insects and even other plants to disappear with it. (Albuquerque, 1990) It is not fully clear as to the extinction at length, since there is more to be understood and studied. So the impacts, which have long-term influences, are difficult to predict easily.
In areas such as agriculture those forms of life, which seem to be insignificant are showing signs of benefits of utilitarian nature. There are farmers who have started to use insects and other animals that compete with or prey on certain crop pests. For the purpose of repelling harmful insects farmers are using plants, which contain natural-toxin compounds. They are called "Biological controls." In comparison to synthetic chemicals, they are cheaper and are effective and safe in several of the cases. It has been found that there are around 80,000 species of edible plants. 90% of the world's food is produced from out of the less than 20 species among them. To solve the food problems of the growing populations could be done by means of conserving the underutilized species. In comparison to domesticated rice, Indian wild rice, which is native to the Great Lakes States, is superior in protein. It is also earning millions of dollars annually, because of the increase in its commercial production. By means of crossing it with Texas wild rice, which is an endangered species, and is also a related species, it could result in a strain, which other regions could also adapt.

endangered species' means any species which is in danger of extinction throughout all or a significant portion of its range other than a species of the Class Insect a determined by the Secretary to constitute a pest whose protection under the provisions of this Act would present an overwhelming and overriding risk to man." A threatened species "means any species which is likely to become an endangered species within
Animal Rights Introduction to the ESA According to Merriam-Webster's Dictionary of Law (1996) the Endangered Species Act (ESA) obligated the government to protect all animal and plant life threatened with extinction. Included in this category are endangered species, which is defined as any species "which is in danger of extinction throughout all or a significant portion of its range." Also protected are threatened species, which are defined as any species "which is
The geneticist must first identify the wild crop, to be utilized as a comparative, (99) stressing that such information to be considered accurate in time and space must be gleaned from archaeological record and only based on the genetic process determined from the modern research in plant and/or even animal genetics. In regards to the animal domesticate the issues become much more complicated, sometimes offering a richer picture of the
Animal Senses Herman, Pack and Hoffman-Kuhnt performed relatively rigorous experiments to determine the source of dolphin recognition of objects; they wanted to discover, among other things, whether "dolphins attained the shape discriminations (of objects) through associative learning or direct perception" (Herman et al. 1998 292). Fukuzawa, Mills and Cooper sought to determine the mechanism by which domestic dogs responded to commands. Greenberg wanted to discover the facts about depth perception in
These abilities are inclusive of memory emotion, belief, desire, intentional actions and an awareness of the future. With these things being understood this theory asserts that mammals not only have physical bodies that are alive but they also function as psychological beings whose existence can get better or worse. Proponents of this theory argue that other mammals have this capacity even though they cannot use human language to articulate
Animal research is a necessity today, and has afforded us the opportunity to create lifesaving drugs and vaccines, new surgical procedures and improved diagnosis of disease. Despite the bad press animal activists have given, institutions are given guidelines that guarantee the safe and ethical treatment of research animals. Most scientists agree that continued animal testing is essential to develop new vaccines and medicines, and that computer and mathematical models are
animal species studied for this report include the Gray Wolf (Canis lupus) and the American Black Bear (Ursus americanus). The plant species studied are the Venus Flytrap (Dionaea muscipula) and the Prickly Pear cactus (Opuntia humifusa). Each of these species has been observed at the local zoo, and further research has been conducted to learn about the environment in which each species would live in a natural setting. The
