If the resources of space were opened to use and viable life-supporting habitats were built, the Earth would no longer define the limitations of growth.

From 1993 to 1996, 14 troops were observed in Silent Valley National Park, Kerala, one of the most undisturbed viable habitats left for them.

Coral reefs and seagrass beds are deteriorating, reducing viable habitats for seahorses.

Human development has eliminated a large portion of its viable habitat.

The two ways to reverse this trend of habitat loss are conservation of currently viable habitat and restoration of degraded habitats.

Many factors play an important role in determining a viable habitat for M. grisescens.

Now, almost ten years later, the site is a viable habitat for urban wildlife.

But Data's analysis suggested that millions of years hence, the surface life would be gone, the oceans frozen over, and only the deep-sea vents would remain viable habitats.

Smuggling of dart frogs is less common elsewhere, but still problematic as it kills large numbers of animals and frequently degrades or destroys viable habitat.

It is believed to be one of the last viable habitats for this species, though even here, B. kachuga are rare.
