A Sustainable Travel Project is to protect and preserve the natures natural habitat and its Eco-system in our mother earth. It aims to protect the nature from humans greed who are destroying them for their personals and by creating them into artificial places. Here in this picture, we see that the bridge was built to travel short between two lands. And when we go against the nature it destroys what we build. Some places are meant to be kept as the nature needs. We shouldn't build artificial nature with the Eco-system.
