In many people's eyes，plants are quiet and passive.They can't talk.They can't walk.（1）.
   Or can they？A new BBC documentary series，The Green Planet，gives us a new look at plants.Released on January 10 on Bilibili，it uncovers the wonderful and dramatic ways that plants behave.
   Plants compete against each other to live.Each species has its own ways of defense.In 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 filters（透過） through it.（2）.But they are caught up in a vine（藤蔓） that tries to take a ride.Finally，they are both overtaken by a fast-growing balsa tree.As the balsa's leaves are smooth，the vine can't get a hold.Similarly，some trees make poisonous sap（毒汁） to protect themselves.
   （3）.In deserts，the roots of Euphrates popular 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.（4）.
   The series not only lets us wonder at the plant world but pushes us to understand that plants are important."（5）.We depend upon them for every mouth of food that we eat and every breath that we breathe，"said David Attenborough，presenter of the series.It's time to look after wild plants just as carefully as our houseplants.
