The Balance of Nature

What happened to the ecology when five sailors, shipwrecked on an undiscovered island off New Zealand, left a bull, a cow, and a pair of rabbits behind when they were rescued. How adaptation can be so intricately specific that if one seemingly minor factor is changed, a species can die—or be killed through the introduction of a plant or animal to a region where it has no natural enemies. Consider the global consequences of the fact that by the middle of the next century, 15% of today’s plant species will be extinct! And that international trade and travel constantly transposes species from their natural to new habitats. (28 minutes)
