SAND

This decade the world woke up to another scarcity: sand. The second most consumed natural resource after water, excessive use of sand has driven rivers to dry; local ecosystems being ravaged. Such has been the impact that the UN Environment came out with scary report on its impacts on the planet’s health. India has been reporting widespread cases of violent conflicts over illegal trade of sand. We are in fact now importing sand for construction. Now there is a scramble to evolve alternatives to sand.
