Everyone likes birds. What wild creature is more accessible to our eyes and ears, as close to us and everyone in the world, as universal as a bird?

Birds are the most popular group in the animal kingdom. We feed them and tame them and think we know them. And yet they inhabit a world which is really rather mysterious.

The nature of human beings is that they'd far rather face the disaster that is happening tonight than the one that is happening tomorrow.

Can a growing human population still leave space for wildlife?
