What is the need of wildlife conservation?

a. Conservation preserves the ecological diversity and our life support systems water air and soil. If a species is lost, in long run, it may upset the natural balance and as a consequence makes the system vulnerable.

b. It also preserves the genetic diversity of plants and animals for better growth of species and breeding. All the native species possess genetic reservoir and provide genes for improvement of existing plant and animal life to solve present food problems or production of disease resistant varieties.
c. In agriculture, we are still dependent on traditional crop varieties. Fisheries too are heavily dependent on the maintenance of aquatic biodiversity
d. AFTERALL THIS EARTH BELONGS TO NOT ONLY FOR HUMANS BUT ALSO FOR ALL ORGANISMS.
e. Economic benefit: wilelife is a source of income to recreation and tourism industry. Most popular tourist atractions are the wildlife sanctuaries and national parks.
Many plants have medicinal value. Some animals like shrimps and crabs provide medicines against fungal infections
f. Game value. Wildlife has its worth as game also. In several western countries, million of people hunt or fish for recreation, spending millions of dollars for such sport
g. Scientific value: scientists of wildlife in biology and medicine are direct value for humans. For examples sea urchins have helped greatly in the understanding of human embryology, rhesus monkeys in present blod groups, antlers of deer in determining the degree of radio active contamination of environment.
h. Aesthetic value: aesthetic values such as the taste of wild berries, fragrance of wild flowers compel us to preserve them.
A world without melodious birds, graceful beasts and thick forest would be poorer place for humans to live in.
