Water security is considered one of the top global risks. Today, at least 663 million people lack access to safe drinking water.
A World Bank report published in May 2016 suggests that water scarcity, exacerbated by climate change, could cost 6% GDP, migration & spark conflict.
By 2025, about 1.8 bn people will be living in regions or countries with absolute water scarcity.
This petition is important for future as well as present generation. Let us sign it to have a law to save water by re-using upper floor's washing machine/bath's waste water to flush toilets of lower floors.
