From the broad leaves of Britain's forests to the curious patterns of desert succulents - uncover how leaves shape our world. Unless you're an avid gardener, leaves might slip your notice. But from the smallest pavement crevices to the trees that line our streets, they're everywhere. And leaves power much of the natural world - from salad to soil. They are solar panels, rainmakers, lunch boxes, chemistry sets, mulch-makers and building material - all in one. From the lush rainforests of the tropics, where the fight for light has given rise to magnificent leaves of all shapes, sizes and colours, to the strange, spectacular adaptations of desert plants, Jonathan Silvertown revels in the wondrous science and evolutionary success of these magicians of the natural world.
