A new study published on Monday revealed that three quarters of freshwater species living in East Africa’s Lake Victoria basin face the threat of extinction

The International Union for Conservation of Nature (IUCN) assessed that 76 percent of these creatures, including freshwater species like fish, mollusks, dragonflies, crabs and aquatic plants living in Victoria Lake and its surrounding, area are endangered.

The study noted that industry and agriculture have polluted the lake, and blamed over-fishing as well, the German News Agency reported.

Will Darwall, a co-author in the study, and head of the IUCN’s freshwater biodiversity unit said that the effects on communities that depend on the lake for their livelihoods could be disastrous.

According to the World Bank’s estimates, over 40 million people in Kenya, Tanzania and Uganda directly or indirectly rely on the lake.

A 10-carat blue diamond which could fetch $20 million when it goes under the hammer later this month was presented by auction house Sotheby's in Geneva on Thursday.

The cushion-shaped piece, known as the "Mediterranean Blue Diamond," was mined in South Africa and displayed a rare color that qualified as fancy vivid blue, Sotheby's said.

"The market for coloured diamonds continues to go from strength to strength," said Jessica Wyndham of Sotheby's, added that she expected a price in the region of $20 million.

In 2016, another vivid blue diamond sold for 56.8 million Swiss francs ($68.7 million) at a Christie's auction in Geneva.

Sotheby's high jewellery collection, which includes other coloured gemstones, was presented to journalists in Geneva ahead of a live auction scheduled for May 13 at the Mandarin Oriental Hotel.
