Why to save the endangered ?
“Diversity of life and living systems are a necessary condition for human development”
Since life began on this planet, countless species have come and gone, rendered extinct by naturally changing physical and biological conditions. Since extinction is part of the natural order, and if many other species remain, some people ask: “Why save endangered species? What makes these animals and plants so special that money and effort should be spent to preserve and recover them?” While extinction does occur naturally, unfortunately the accelerating decline of our wild animals and plants is less and less a result of natural events. Most dangers to wildlife are from habitat loss and degradation, environmental pollution, the introduction of exotic (non-native) organisms, and over exploitation; all generally a direct result of human activities.
Many question the importance of maintaining biodiversity in today’s world, where conservation efforts prove costly and time consuming. Species should be saved for “aesthetic and moral justifications; the importance of wild species as providers of products and services essential to human welfare; the value of particular species as indicators of environmental health or as keystone species crucial to the functioning of ecosystems; and the scientific breakthroughs that have come from the study of wild organisms”.In other words, species serve as a source of art and entertainment, provide products such as medicine for human well-being, indicate the welfare of the overall environment and ecosystem, and provided research that resulted in scientific discoveries.
NEED OF SAVING THE ENDANGERED SPECIES
Conserve biodiversity
Influences and supports the survival of other species
Offers opportunities to protect whole landscapes or marine areas
The chemical secrets of most species have yet to be unraveled for potential benefits to mankind.
A planet with high biological diversity is a planet worth living on.

Facts About Endangered Ones..

Threats to birds..amazing facts!!
- One of the major threats faced by birds is from the loss as well as deterioration of their habitat. Trees are being felled at a rapid pace to make way for human settlements as well as agricultural activities. Even aquatic habitats are being drained, plowed, filled in, and channelized. Last but not the least, the introduction of invasive plant and animal species is also altering the natural habitat of birds.
- Birds are also facing increased competition from one another. Especially the native species of birds are finding it difficult to cope up with the exotic species.
- The direct exploitation of birds by humans is reaching alarming proportions. Human activities, such as hunting and capturing birds, are leading to a rapid decline in the bird population.
- Birds are highly sensitive to chemicals and toxins and can become fatally sick from inhaling them, either by eating or through their skin. It has been found out that, along with DDT, pesticides and oil spills, even herbicide spraying on lawns leads to death of the birds.
- Even indirect pollution of the atmosphere is having an effect on the population of birds. Things like acid rain have been discovered to affect the population of forest birds. It washes away the calcium of the soil and decreases the amount of calcium-rich prey of the birds, affecting their diet and thus, their population.
- The nesting, feeding, and roosting areas of birds have faced a lot of disturbance from the human beings, affecting their population.
Birds too in danger!!
