A lot of us just dont care what happens to animals and never think twice when a Mall, factory are build in certain places in our country or across the world and people think that animals simply relocate further back or just dont give a damn either way.
 
I want to share this link with you all and what some studies show has happen to the world due to the loss of large predators and how it effects the ecosystem.
 http://www.sciencedaily.com/releases/2011/07/110714142128.htm
 The decline of large predators and other "apex consumers" at the top of the food chain has disrupted ecosystems all over the planet, according to a review of recent findings conducted by an international team of scientists and published in the July 15 issue of Science. The study looked at research on a wide range of terrestrial, freshwater, and marine ecosystems and concluded that "the loss of apex consumers is arguably humankind's most pervasive influence on the natural world." 
 
 

  • The extirpation of wolves in Yellowstone National Park led to over-browsing of aspen and willows by elk, and restoration of wolves has allowed the vegetation to recover.
  • The reduction of lions and leopards in parts of Africa has led to population outbreaks and changes in behavior of olive baboons, increasing their contact with people and causing higher rates of intestinal parasites in both people and baboons.
  • A rinderpest epidemic decimated the populations of wildebeest and other ungulates in the Serengeti, resulting in more woody vegetation and increased extent and frequency of wildfires prior to rinderpest eradication in the 1960s.
  • Dramatic changes in coastal ecosystems have followed the collapse and recovery of sea otter populations; sea otters maintain coastal kelp forests by controlling populations of kelp-grazing sea urchins.
  • The decimation of sharks in an estuarine ecosystem caused an outbreak of cow-nosed rays and the collapse of shellfish populations.

these are just small excerpts and not the full article from the link i posted.

Sea otters maintain kelp forests (left) by preying on kelp-grazing sea urchins. In the absence of sea otters, the kelp forest is replaced by an "urchin barren" (right). (Credit: Photos courtesy of J. Estes)

I would like to see more cities build green urban sustainable communities that would promote healthy city living. If cities become healthier, safer and more livable; more people will choose to live in inner city, which will help reduce the sprawl into wild animal habitat. The further we move to the wilds the more animals that will be displaced and forced out of their own environments or be killed as a result of our sprawl.
