The Gulf of Oman turns green twice a year, when an algae bloom the size of Mexico spreads across the Arabian Sea all the way to India. These toxins have infiltrated whole marine food chains and have, in rare cases, killed people, according to the UN science agency. The algae blooms pose a number of threats to Oman, whose fishing and trading ships have plied these waters for centuries. He says the blooms are growing bigger and lasting longer, displacing the zooplankton at the bottom of the local food chain. A wave colored with dark green algae washes on the beach of Bandar al-Jissah, Oman.
