Essay essay on vanishing wildlife
Answers
Lets start with an example
The great white shark is one of the most notorious marine predators in the world. It was hunted to near extinction by Europeans in the 1600s and 1700s, and has since dwindled from about 15,000 to about 400-500 at the lowest estimated number. Its population is now in a precarious position – it declined almost tenfold between 1966 and 1975, yet remains at or near its pre-1900 peak, with populations declining to levels not seen since the late 1800s.
To prevent them from going extinct, the US Environmental Protection Agency and Marine Life Act mandate that populations of other killer whales be regulated. By contrast, while killer whales have not experienced extinction, the threat they face is far greater – by 2010, global populations stood at almost 13 million, mostly located in shallow waters, such as the Hawaiian, California and Florida coastal ocean basins (Habitats 8, 13, 20).
These bottlenose dolphins have become the world's leading marine predator; they can kill a larger percentage of fish and mammals than the largest tuna
The World Health Organisation (WHO) says that the health and economic problems caused by killer whales go largely.
This is where I first came across the term "ecosystem service" and when speaking to a few ecologists about it they said "we are not about the environment". What's interesting to me is that when you think about it, most of us are pretty much aware that the environment is constantly getting worse.
For example there are lots of people who feel there are environmental crises and need to work on them but the idea of helping the ecosystems is sort of a foreign concept to them. I think we need to think about our own conservation efforts in the same way. There are definitely some things we can do to reduce the impact of impacts on the environment but it might take some time to realize it.
So I wanted to start here with a post on "ecosystem service" in which I attempt to address what it actually means to provide services to the earth. So let's take our example from an ecological perspective and start from a place of comfort
Evaluating declines in an environment's ability to support birds as critical for ecosystem functioning is a critical tool in predicting ecological shifts and resource allocation.
The number of birds in the wild fluctuates year to year depending on seasonal and cultural patterns as well as on weather conditions.
A decline could affect many different species, including migratory birds, shorebirds, and sea turtles.

The United States has been gifted with immense natural beauty, varied species of wildlife, flora and fauna, pristine rivers, streams, lakes, and scenic landscape. Before the colonization of the United States in the sixteenth century, its natural beauty and wildlife was virtually unharmed and untouched. The vast frontiers were tribal lands, and the various tribes in essence sustained themselves from whatever the land provided. They were known to have lived in harmony with nature and the environment.
The first settlers began arriving by the early 1600s. This was followed by waves of migrant population from Britain and Europe. The plentiful lands, abundant wildlife, and the wild frontiers beckoned too many settlers at that time. Subsequently, outings for game became popular means of leisure and an easy source of food. Settlers would often kill birds and wild animals for commercial trade of fur and leather, and at times even for pleasure. Over the next two centuries or so, millions of varied species of birds such as robins, quails, grouse, pigeons and wildlife like bison, deer, goat, seals, and many others are thought to have been killed.
