Flowers are a part of our life and a part of nature. Nature is so vast that we can not imagine its existance. As science has progressed in every field but its value is worthless before nature. We think, work and we are leading our lives according to our own ideologies. But our ideologies are only confiend to earth's surface. We measure distances according to earth, we describe lengths, masses and any other unit in terms of our earth's property. But nature is not only confiend to earth rather earth is a little part of nature. If earth losses its existance then there will be no effect on nature. If you compare science and nature then you will find that science is a grain of sand on the shore of mighty sea.
