Nature is undoubtedly the greatest innovation factory of all times and it has got lot to teach and inspire us. If we analyze most of the living things or organisms, the 'in-situ procurement' of resources needed for their efficient survival is clearly visible. In short, they just develop/construct or simply innovate new technologies they require. Nature is basically a vast eco-library of materials, resources, energy systems, information, technologies, management techniques etc. We humans need to explore this library and derive solutions to our problems and needs in the bio-way.
