Flowers with their spectrum of colours and fragrance are the most precious and beautiful gift of nature. When in bloom they provide picturesque beauty and pleasant odours to the Earth's ecosystem. Can anyone imagine the Earth without vividly coloured flowers? Yes, this could happen if the devastation being caused by human activities continues to eliminate the pollinators which have played a significant role in the evolution of different shapes and colours of flowers. Conservation of this great floral diversity, therefore, depends upon the conservation of pollinators.
