Oscar winning Hollywood star Leonardo DiCaprio, known for his environmental activism, has raised awareness about the ongoing water crisis in Chennai. DiCaprio shared a photograph of a dry well on his Instagram profile. He wrote: "Only rain can save Chennai from this situation. A well, completely empty, and a city without water. The southern Indian city of Chennai is in crisis, after the four main water reservoirs ran dry. The acute water shortage has forced the city to scramble for urgent solutions and residents have to stand in line for hours to get water from government tankers. As the water levels depleted, hotels and restaurants started to shut temporarily, and the air con was turned off in the city's metro. Officials in the city continue to try and find alternative sources of water - but the community continue to pray for rain."
