There was a strange stillness. The birds, for example - where had they gone? Many people spoke of them, puzzled and disturbed. The feeding stations in the backyards were deserted. The few birds seen anywhere were moribund; they trembled violently and could not fly. It was a spring without voices. On the mornings that had once throbbed with the dawn chorus of robins, catbirds, doves, jays, wrens, and scores of other bird voices there was now no sound; only silence lay over the fields and woods and marsh.
以上这段话来自非常著名的Rachel Carson所著的生态学经典之作《寂静的春天 Silent Spring》。这里面描述了一段“世界末日”般的场景，春日阳光灿烂，然而万物黑暗无声，正第一次应了本书的标题。读过本书的同学应该都了解，这样的假设来自于一个原因——杀虫剂DDT的滥用。
这本书应该是很多朋友入门自然教育或者环境教育和保护领域的“圣经”。虽然DDT现在早已经弃之不用，但是它在生态环境教育和保护领域起到的作用，非常深远。
自然教育不应该停留在本身的字面意思上，也不应该流于书本，更不应该只是“在自然之间”。自然教育就在我们的生活里，渗入到每一个角落，因为我们都是大自然的孩子。
例：自然教育的一个开展地点——杭州余杭青山村
