Nature has always supported human kind. She does this by vast communication systems that exist between members of species, and between the different species. Experiments have shown that music, as an example, is heard by plants, trees, cows, horses, dogs, crocodiles, etc. Humans hear the rustle of the leaves or the creaking of the trees, the different animal sounds, and even the sounds of water and wind.
Often, the communication is simply the way something looks, which makes it a sign. Communication does not need to be acoustic.
Today, walk outside and see how many ways Nature communicates life and need to you. How will you help her?
