I´ve been there this June and can fully understand / support this.
Citation from the petition page (link below):
"In 2017 alone, 29 people drowned in Mauritius.
Ten days ago a lady died on the beach at Le Morne which has a very strong current.
There is no rescue station there.
Ionclub is not allowed to use jetski to save people, just boats, which makes this job impossible on big-wave days.
The petition is for the Mauritius government to put a Coast Guard post on Le Morne beach with jetskis or give permission for Ionclub to use jetskis as it is used by the coast guard around the world on dangerous beaches that receive tourists.
Please sign and help stop the senseless death of tourists.
In the link below contains a video filmed with a drone, it is the last moments of this lady's life, 29th victim of the lack of security on the beach of Le Morne:
