After the boom-bust-boom of the fifties and sixties, the borough went into a third and more severe decline again in the mid-1970s along with much of the Rust Belt so that population was just 2,804 at the 2000 census.

Threats to Biodiversity. The primary threats to the savanna biome are humans (for example, poachers are killing elephants for their ivory tusks and hunting animals to the brink of extinction) and global climate change.
Welcome to the Dynamic Interactions among People, Livestock, and Savanna Ecosystems under Climate Change project. The overall objective of this project is to examine the dynamics between coupled human-biophysical systems in savannas under climate change. Climate change is affecting savanna ecosystems which directly impact livestock and crop production, and peoples' livelihoods. The study area encompasses the savanna areas of Kenya and Tanzania.
