Making Waves in Hong Kong

From the What You Can Do segment at the Kadoorie Farm & Botanic Garden website:

At times, the environmental problems we face can seem overwhelming. Walking amongst the steel and glass towers of central Hong Kong, sometimes it feels as though the natural world no longer exists. Yet, outside the heart of the city, some wild spots still remain. If you come to a pool or stream in one of these places, drop a pebble in the water and see what happens. As the stone vanishes, ripples spread outward across the entire pool. If you drop more stones in, the ripples touch. Working to protect the environment is like dropping a pebble into a vast sea. It takes great courage, but we must do it, no matter how small or weak we may feel. We must strive harder than ever to protect what's left of wild Hong Kong and South China, and find new ways to achieve a balance with nature. Together, we can make waves!
