Causes of Depletion of Wildlife

I am an online writer and studied from university of agriculture fasailabad. Will write 500 to 1000 words.

Factors

The major factors responsible for decline or extermination of wildlife include:

  1. Persecution by human beings.
  2. Loss of habitats.
  3. Pollution.

“No matter how few possessions you own or how little money you have, loving wildlife and nature will make you rich beyond measure.”

Persecution by human beings

The main reasons of persecutions are:

  1. Hunting and shooting of wild animals for fun and amusement or for trophies.
  2. Illegal or legal hunting for food (i.e. for their delicious meat).
  3. Illegal killing or poaching for skin, fur, tusks, oil, plumage, decoration (as stuffed preparation) etc.
  4. Absurd killing by farmers or herdsman living in the near vicinity of jungle of predatory animals (like, tigers, lions, jackels, wolves) which are unjustly accused of killing their domestic animals or livestock.
  5. Trapping of animal so as to keep them as pets.
  6. Animals like monkeys, rabbits etc are trapped live and sold to those who need for medicinal experiments.
  7. In many countries, animals such as monkeys, bears, parrots are caught alive, domesticated and trained for public shows in the streets or in big animal circuses.

“The future of wildlife and the habitat that they depend on is being destroyed.

It is time to make nature and all the beauty living within it our priority.”

2. Loss of habitats

The primary causes of decline of wildlife is the degradation or complete loss of natural habitats. Like other living species, wild animals also need food, shelter, clean water etc. within a territory. If these are denied they will gradually diminish. Ironically, today most of the natural habitats of wild animals and plants are being destroyed by man's activities.

  1. Forests are being ruthlessly today all over the world for agricultural needs, river valley projects, industrial purposes, and for the construction of roads, railways, dams, buildings etc. It has been estimated that every year 40 million acres of forests are destroyed. This deforestation has resulted into fragmentation of natural habitats and reduction in area for free movement of wild animals. The destruction of wild plants of forests for fuel, timber, fodder and other uses has not only deprived wild animals of shelter but their most palatable food.
  2. Overgrazing is another serious hazard afflicting our pastures, forests and mountains. Overexplaitation of range lands by livestock grazing has resulted in more and more denuded hills and valleys, thus snatching away food and shelter from wild haerbivores.
  3. Wetlands are being drained for cultivation and building of roads etc. Wetlands are vegetated with various macrophytes, emergent marsh plants and shrubs. They are the prime habitats for water fowls and semiaquatic vertebrates. They serve as an excellent refuge for a number of migratory birds that feed and breed there.

“Humanity can no longer stand by in silence while our wildlife are being used, abused and exploited.

It is time we all stand together, to be the voice of the voiceless before it's too late. Extinction means forever.”

3. Pollution

Pollution of various kinds have adversely wild animals.

  1. There has been considerable damage to bird life by DDT and other insecticide spraying, especially when heavy concentrated applications have been used. Bird populations, specially 'bird of prey' have been significantly reduced through DDT poisoning. Researches have shown that majority of birds, due to direct or indirect uptake of insecticides, produce eggs with fragile shells which easily breakaway when mother sits on it for incubation. Moreover, the elimination of insects from any piece of land is bound to affect the insectivorous bird living there.
  2. Millions of oceanic birds are killed every year all over the world by oil spillage from oil tankers in the sea.
  3. Noise pollution by different transporting media like heavy trucks, buses, rails, aeroplanes have adversely affected the wild life. Wild animals are shy of uman presence and hence the greater movement of men through their habitats have upset their feeding, hormonal and reproductive behavoiur.
  4. Today, our rivers estuaries and shallow offshore areas have become the waste bin for million of tonnes of waste products from human activities. The aquatic resources are becoming increasingly polluted by industrial waste, domestic sewage and oil spillage,. Due to water pollution the biota has been seriously affected. Stocks of fishes have declined and animals like oyesters, mussels have become unfit for human consumption.

“A simple act of kindness and compassion towards a single animal may not mean anything to all creatures, but will mean everything to one.”

Overall

The main reasons of persecutions are:

  1. Hunting and shooting of wild animals for fun and amusement or for trophies.
  2. Illegal or legal hunting for food (i.e. for their delicious meat).
  3. Illegal killing or poaching for skin, fur, tusks, oil, plumage, decoration (as stuffed preparation) etc.
