Communication
The world we are living in is amazing. There are countless living things. How can they live harmoniously? The answer is communication.
Communication, of course, doesnt need to be in words. We can talk to each other by a smile, a frown, a shrug of our shoulders, and a gesture with our hands. Shaking hands is a very common gesture, which is performed both on initial greeting and departure. We know that birds and animals use a whole vocabulary of songs, sounds, and movements. Bees dance their signals, flying in certain pattern that tell other bees where to find nectar of honey.
Can plants talks? Yes---but not in words. We have reasons to believe that trees do communicate with each other. Not long ago, researcher learned some surprising things. First, a willow tree attacked in the woods by caterpillars changes the chemistry of its leaves and made them taste so awful that the caterpillars go disgusted and stopped eating them. Then, ever more astonishing, the tree sent out special vapors---an alarm signal stimulating its neighbors to change the chemistry of their own leaves and make them less tasty
Communication is so important in the nature world. As human beings we should communicate with each other to make the earth peaceful.
