A simple stroll around the park amidst some birds provides a fresh breath of life and charges our batteries. Apart from a bird feeder in the backyard, we can also take up other active pastimes, such as hiking, hunting, canoeing, or wildlife photography, to relieve our parched nerves. Since prehistoric times, animals have been highly useful to us in providing food, clothing, and a source of income.
Studies indicate that woodpeckers are capable of destroying 90% of codling moth larvae residing under the bark of trees. This shows the significance of wildlife and wildlife habitat for preserving genetic diversity. Hence, places, where agriculture, forests, and fisheries depend on crops or stocks, can ensure that such living resources are enough to withstand the ever-increasing list of threats. Further, in medicine, the development of new drugs and treatments is largely dependent on wildlife and wildlife habitat. Interestingly, most pharmaceutical products are a result of discovering or developing wildlife species, not discoveries made through traditional chemistry principles. Today, most medicinal remedies contain at least one ingredient derived from a wild plant or animal.
