Sustainable roads
SCIENCE & TECHNOLOGY
There is an increasing awareness for the need to have infrastructural development that is in sync with the surrounding eco-system. Our ancestors certainly knew about this and lived by this philosophy as is evidenced by some architectural / engineering wonders that have stood the test of time. The 39,000 kilometre long Inca road is one such glittering example of development that is in harmony with nature. I came across a nice article on BBC website recently that elaborates on this topic. Given below is the link to the same and I hope you find it as interesting as I did.
