What Will Happen to Biodiversity When the World Becomes A Giant City?

June 11, 2008
“As a species we have lived in wild nature for hundreds of thousands of years, and now suddenly most of us live in cities—the ultimate escape from nature,” says Kareiva. “If we do not learn to build, expand and design our cities with a respect for nature, we will have no nature left anywhere.”

Indeed, biocide is occurring at an alarming rate. Experts project that at least half of the world’s current animal species will be completely gone by the end of the century. Wild plant-life is also disappearing. Most biologists say that we are in the midst of an anthropogenic mass extinction that is at least partially caused by human encroachment on more and more areas of the planet. Numerous scientific studies confirm that this phenomenon needs to be addressed quickly.

A new study outlines the uncomfortable question of what happens to the planet’s biodiversity when cities take over the world.
Cities are growing, and they’re growing fast. It is projected that urban growth will create an additional 350,000 square miles of cities roads, buildings and parking lots—covering a combined area the size of Texas—by 2030.
Every week humans create the equivalent of a city the size of Vancouver. What will this staggering growth mean for both nature and people?
it means significant species loss and a further decline of natural resources like fresh water. They say we need to prepare—now.

“While the effects of urbanization are very localized, cumulatively it
is a big threat to biodiversity,

According to the United Nations, humans officially became an urban
species in 2007 when a milestone was reached. Over half of the world’s
population now live in cities.
