Not long ago, the United Nations warned that water scarcity could be experienced by 40 percent of the world’s population by 2030. Last week, top U.N. scientists reported that problems associated with a warming climate, including drought, water scarcity and pollution, are likely to be worse than previously thought unless we work to hold the average global temperature rise to no more than 3.6F(1.5C). These warnings may seem daunting, but some of the world’s most influential companies are making strides that could significantly help alleviate worsening global water challenges.
