Average Growing Nation Can Expect 10.8 Percent More Threatened Species by 2050

COLUMBUS, Ohio – The ongoing global growth in the human population will inevitably crowd out mammals and birds and has the potential to threaten hundreds of species with extinction within 40 years, new research shows.

Scientists at The Ohio State University have determined that the average growing nation should expect at least 3.3 percent more threatened species in the next decade and an increase of 10.8 percent species threatened with extinction by 2050.

The United States ranks sixth in the world in the number of new species expected to be threatened by 2050, the research showed. (more…)

State-Mandated Planning, Higher Resident Wealth Linked to More Sustainable City Transportation

COLUMBUS, Ohio – Transportation practices tend to be more environmentally friendly in wealthier metropolitan areas located within states that mandate comprehensive planning, new research suggests.

The study involved an examination of 225 U.S. metropolitan areas between 1980 and 2008 to gauge how sustainable their transportation practices were and determine what kinds of socioeconomic factors appeared to influence those practices. (more…)

COLUMBUS, Ohio – Water-associated infectious disease outbreaks are more likely to occur in areas where a region’s population density is growing, according to a new global analysis of economic and environmental conditions that influence the risk for these outbreaks.

Ohio State University scientists constructed a massive database containing information about 1,428 water-associated disease outbreaks that were reported between 1991 and 2008 around the world. By combining outbreak records with data on a variety of socio-environmental factors known about the affected regions, the researchers developed a model that can be used to predict risks for water-associated disease outbreaks anywhere in the world.
