Endangered species are classified as below:

1. The vulnerable species: These are in risk group because of their naturally declining numbers.

2. The threatened species: These kinds of animals are available in adequate number. But these are in danger zone due to the possibilities of extinction.
Ex: Indigo snake and Red kangaroo

3. The endangered species: These are under the category of immediate extinction and require special care towards their protection.
Ex: Siberian tiger and snow leopard

4. The extinct species: These animals are already extinct.
Ex: Passenger pigeon, dodo and stegosaurus etc.

6. Place decals on windows to stop bird accidents.
7. Slow down when driving.
8. Avoid supporting the market in illegal wildlife including: tortoiseshell, ivory and coral.

    What can satiate an ever growing populus then? Only man and man alone with salts, silt, minerals, metals and transformers shall remain. The ultramodern man doesn't.

    anymore relish on the flesh, and very existence of animals, plants, for that sake any invertebrates or fish. No co-habitation. No nature. All one faith, one motto and.

    e-trons. The basic theme is transforming this planet into an ellipitcal surface equipped with bizarre terminators, robos, and man machines. All that creation of God is.

    sheer fun to hunt. Already humans are successful in eradicating entire genes, classes and wiped out millions of species from earth and this pursuit shall continue till the day.

    when man can find deserts, rocks and deciduous lands stretching millions of square miles, as if its an entire new planet unseen, unheard of, unrelished. The very aim is to bring.

    the extreme temperatures onto the planet such as soaring heat at 50 to 70 degrees celcius, at nights its chilled but one does not find dew or ice, but mist.

    If at all there is any water, waterhole or some durable water resource left, that should be full of froth, and rest of population that survived, but are living with bear minimal necessities perish just exactly as the souls in the Namibia, Ethopia, Cambodia and other famine stricken nations. The very purpose of life and gist is to give hope, life and eternity in the underground skapers that contain nothing but tunnels and dwelling made of metals and rock solid advanced materials. There shall also be nature which survive such adversaries too, and loved by the psychos, the vultures, eagles, hyenas, crocs, sharks, cat fishes, roaches, shit-bugs, rolling bugs, a new breed of insects that crawl into human brains and breed on them, new variety of fish that become savageous as in the Hollywood movies (piranah), and cannibalism shall be the order of the day. Its socially accepted just as the same sex, animal hunting, bird hunting etc. Yes there shall be samples of large mammals and fish, which were in millions and perhaps outnumbered millions in mid 19th century. These samples are exibited in zoo's as single dwelling species of each kind within maximum area of 2 to 3 acres. I mean the entire zoo.

    The day is not far enough as the global effects that we see today is the tip of the iceberg to perish the existence of races, humanity and nature itself. Imagine what it best looks soon after a nuclear explosion. That is what is this planet is to be made for, that is what its nature deserves. What an idea to spread, spread among ultramodern humans, making nations.
