Some people collect coins, some people collect books; people like Eric Dinerstein collect sightings of rare species. In The Kingdom of Rarities, newly released in paperback, Dinerstein shares stories from his career spent traveling the world in search of Andean cocks-of-the-rock, armadillos, and saolas. As he travels, he shares stories of how these species affect the ecosystems they live in and how scientists are working to learn more about them and how they can be protected.

With spring finally starting to show its face, we're thinking about everything that's green and growing. But as Yvonne Baskin shows in Under Ground: How Creatures of Mud and Dirt Shape Our World, we'd be nowhere without that most overlooked of substances: dirt. In the first chapter, she introduces an amazing world that holds two-thirds of the planet's biodiversity, from gigantic fungi to ancient microbes that can live in boiling hot springs or under sheathes of polar ice.

Back in November of 2013, President Obama issued an executive order on climate preparedness.

A few weeks ago I asked some of our authors to create their own executive orders to improve our handling of the environment.

In his recent New York Times article, “Overpopulation is not the problem,” geographer Erle Ellis comes to two optimistic conclusions: (1) we can feed our planet’s growing human population, and (2) we can do that without further destroying nature. Ellis’s optimism is to be commended. Ultimately, we are not going to fix the environmental problems we face without an endgame plan, and an effective endgame plan simply cannot be devised or implemented without optimism.
