How economic growth in low-income countries can also protect biodiversity

Phys · · 658 words · By Brad Robideau

The article discusses a study from the University of Minnesota suggesting that accelerated economic development in low-income countries could protect biodiversity. It argues that higher incomes lead to lower population growth and improved agricultural productivity, which may reduce the need to convert natural ecosystems into farmland.
