DIVENTURES



EDITOR NOTE

Dear readers ... Welcome to the August 2020 issue, the eighth issue of Diventures Magazine. Finally ... we dived after a long period, and many of us noticed the difference and noticed the environmental impact during the lockdown, so I hope that all of us help in the preservation of our marine environment, so that this positive effect lasts for long. We would like to thank photographer Robert Stansfield for gifting us a cover photo of a smiling Parrot Fish. Finally ... We ask for your support to us on the Patreon platform to help us continue, and for Diventures Magazine to remain free to reach its message to all those interested in the field of diving.

Environmental Disaster in Mauritius As if this planet is destined to not recover from the human influence on it, after COVID19 lockdown and its positive impact on the environment, fuel leaked in Siberia in Russia, and not a while

later, another oil leak occurred in Mauritius. Mauritius government officials said today, Saturday, that the Japanese ship that spilled tons of oil near the protected areas off the island in the Indian Ocean split in half, causing the remaining fuel to leak into the clear waters.

7

Environmental groups have warned that the damage to coral reefs and coastal areas may never be compensated. The ship "MV Wakachio" collided with coral reefs on July 25, and its hull began to crack days after heavy waves collided with it, as 1000 tons of fuel began to leak from the tanker on the sixth of August. After the government declared an environmental emergency,

thousands of volunteers rushed to the beach to set up makeshift barriers of cloth stuffed with sugar cane leaves and even human hair, attached to empty bottles to keep them afloat. The country of 1.3 million people relies heavily on tourism and has been hit by economic problems due to travel restrictions imposed

during the coronavirus pandemic.
