It is part of human nature to strive to adapt to ones environment. Without a desire to do so, our species could not have survived. But efficiency is key, and the plasticity of the human mind allows it to nourish itself with experience and sense and improve itself. Part of the uplifting beauty of a flower, any flower picture, dripping with water is the abundance of nourishment that surrounds it. We imply that flower has everything it needs to thrive and become the best that it can be, and this implied, subliminal recognition hits home in human perception as it reminds us of our own struggle and gives us hope that, in the right circumstances, we can thrive too.
