Tough conservation choices? Ask evolution - December 2008
If your home were on fire, what would you take with you when you fled? The choice could be tough, with childhood toys, photo albums, and important documents all vying for attention. Unfortunately, we face a similarly difficult decision when it comes to conservation. Human activities have triggered the Earth's sixth mass extinction. Nearly 50% of all animal and plant species could disappear within our lifetime. As we race to staunch this rapid loss of biodiversity, we'll need to make choices, but where should we concentrate our efforts?
