Extinct Animals That May Still Roam the Earth - Animal extinction may have been caused by natural occurrences such as climatic heating or cooling or changes in sea levels, scientists also agree that an asteroid striking the earth was to blame for the loss of the dinosaurs.
In more modern times causes of extinction have been dominated by the activities of humans; habitat destruction (due to agricultural land conversion, deforestation or urbanisation), increased human population, pollution, global warming, overhunting/fishing, poaching or the introduction of alien species to an environment.

Passenger Pigeon
oddmygod.com - Traveling in flocks up to a mile wide and 300 miles long, the passenger pigeon was once the most numerous bird on the planet. With 5 billion individuals comprising up to 40% of the total bird population in north America. The species vanished in the wild by the 1900s due to hunting and loss of habitat. But are they gone forever? There are still sightings today, and scientists plane to clone a preserved specimen.
Thylacine
oddmygod.com - The Thylacine, Commonly known as the "tasmanian Tiger" was once the largest known carnivorous marsupial. They were found throughout most of the Australian island of tasmania, before being hunted to extinction in the wild human settlers. The Australian Government claims that recent sightings are only domestic dogs. But some believe this is part of conspiracy to deny the existences of thylacines in order to allow the logging of gold growth forests.
Wooly Mammoth
oddmygod.com - Standing up to 11 feet tall and weighing up to 6.6 tons, the wooly mammoth lived alongside early humans in ancient Eurasia and North America. Due to a combination of hunting and climate change, the last known mainland mammoths died in Siberia nearly 10.000 years ago. But isolated populations survived on Wrangel Island in the Arctic Ocean until 4.000 years ago, raising the possibility that some may still survive in remote wilds of Siberia.
