Men have been hunting and killing whales for centuries. Early whalers hunted for survival, but their motivation may have changed once there was money to be made. Whaling for profit has been banned since 1986, but whaling for scientific research is still allowed in certain areas, causing much debate.
Flagship species like leopards, whales and wolves grace wildlife calendars, bring in big conservation dollars and help regulate their ecosystems. But what about the tiny guys you won't find on your calendar? How important are they to Earth's biodiversity?
Our planet would be a much different place without its richly diverse ecosystems full of plants, animals and microorganisms. What poses the biggest danger to the millions of species that call Earth home?
Since the Age of Discovery, we've been toting plants and animals to parts of the world where they don't belong. While most transplants die, some become invasive. How can these newcomers lead to breakneck-pace evolution?
If it takes $1 million a year to save the California condor, how much would it take to save every endangered species? Is it possible, and how can we save species we don't even know exist?
A wilderness becomes a grid work of streets, lights and skyscrapers. Every day, we remake the world a little more to our liking. What has that meant for the planet?

Despite the world's rebound from the 2008 food crisis, high food prices continue to be a problem. What is food security, and why is it so important to our future on Earth?
Saving the rainforest used to be about protesting the number of trees that were cut down. But some researchers propose that reforestation could combat habitat loss and animal extinction. Can we really bring a decimated rainforest back to life?
