Hollywood star Leonardo DiCaprio takes environmental issues seriously and this is not a new fact. As the water crisis gets intense in Chennai city of Tamil Nadu in India -- the star took to his Instagram profile to voice his concern.
He shared a report of BBC on Instagram and captioned it, "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 completely 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 tanks.
"As the water levels depleted, hotels and restaurants started to shut down 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," Leonardo wrote.
One of the most vocal environmentalists in Hollywood, he further wrote a call-to-action: "We can change the world!"
For those unaware, several parts of Tamil Nadu are grappling with acute water shortage. The Centre had last month issued a drought advisory to the state in the backdrop of depleting water levels in its reservoirs.
