In many people’s eyes, plants are quiet and passive. They can’t talk. They can’t walk. And they can’t think like us. Or can they? A new BBC documentary series The Green Planet gives us a new look at plants. Released on January 10th on Bilibili, it uncovers the wonderful and dramatic ways that plants behave. Plants compete against each other to live. In the rainforests, different kinds of plants race for sunlight. The forest floor is described as a “battlefield” in the series as only two percent of the sunlight goes through it. Some plants spread their big leaves to reach light. But they are caught up in a vine (藤本植物) that tries to get the sunlight. Finally, they are both overtaken by a fast-growing balsa (轻木) tree. As the balsa has slippery hairs on its leaves, the vine can’t get a hold. Similarly, some trees make poisonous liquid to protect themselves. Plants also help each other and even communicate. In deserts, the roots of Euphrates poplar (胡杨) are connected. If a tree finds water, it will share it with others through the roots. Studies also show that plants use fungus (真菌) in the soil as a way to “talk” to each other. It’s kind of like how Wi-Fi works. If a tomato plant gets a leaf disease, it can tell nearby plants about it. The Green Planet not only lets us amaze at the plant world but pushes us to understand that plants are important. “Plants are the basis of all life, including ourselves. We depend upon them for every mouth of food that we eat and every lungful of air that we breathe,” said David Attenborough, presenter of the series. It’s time to look after wild plants just as carefully as our houseplants.【缺少答案,请补充】
