The goal is to create a tool to assist researchers and policymakers to better understand biodiversity, patterns of plants and animal behavior. Close to 2 million people from more than 200 countries have contributed to the website. The project is likely to cost $100 million and has recently received $12.5 million from private foundations.

Users can contribute a photograph or observation and experts will verify all submissions. The encyclopedia will help scientists understand the impacts of global warming on biodiversity and the movement of species to cooler climates.
