Human Life Expectancy Vs. Endangered Species

According to a new study by the University of California Davis, as human life expectancy increases, so does the percentage of invasive and endangered birds and mammals. At first glance, this statement may trigger the phrase "correlation does not mean causation." However, this research team led by Aaron Lotz analyzed a combination of 15 social and ecological variables -- from tourism and per capita gross domestic product to water stress and political stability in 100 countries, which included 87% of the world's population and 74% of earth's total land. Even when compared with these other variables, increased human life expectancy still repeatedly surfaced as the key predictor of global invasions and extinctions. What implications does this study have? Do you see any viable solutions? Please share with us your own thoughts and reactions!
