Benjamin Kahn

Benjamin Kahn (born 1955) is an Israeli marine biologist and environmental activist.

His work includes ecological improvements of the Red Sea reef, where damage began in 1997 with the advent of fish farming, resulting from tons of waste into the reef.[1] Kahn appeared on Time Magazine's list of "Heroes of the Environment" October 2007.[2][3] Kahn's work has been done largely through Zalul Environmental Association, an environmental non-profit organization founded by his billionaire philanthropist father and dedicated to protecting the seas and rivers in Israel. Kahn serves as chairman of Zalul.[4][5][1][6]

Kahn is the founder and CEO of Atlantium Technologies, a water purification technology firm established in 2005 that developed a hydro-optic ultraviolet technology used as a non-chemical means to control biofouling.[7][5] In 2017, Atlantium was chosen to install this system to prevent the clogging of piping at the Hoover Dam by quagga mussels.[5]

Kahn also serves as President of Coral World International Ltd., an operator of marine parks that specializes in ecologically-friendly tropical life systems in symbiotic environments.[8]

Heroes of the Environment (2007)

Heroes of the Environment is a list published in Time Magazine. The inaugural list was published in October 2007. The list contains 43 entries, individuals or groups that have contributed substantially to the preservation of environment, and is divided into four categories: Leaders & Visionaries, Activists, Scientists & Innovators, and Moguls & Entrepreneurs.

The list has been commented and discussed worldwide, in newspapers or by organizations.

List of Israeli Ashkenazi Jews

This is a list of notable Israeli Ashkenazi Jews, including both original immigrants who obtained Israeli citizenship and their Israeli descendants.

Although traditionally the term "Ashkenazi Jews" was used as an all-encompassing term referring to the Jews descended from the Jewish communities of Europe, due to the melting pot effect of Israeli society the term "Ashkenazi Jews" gradually becomes more vague as many of the Israeli descendants of the Ashkenazi Jewish immigrants gradually adopted the characteristics of Israeli culture and as more descendants intermarry with descendants of other Jewish communities.

The list is ordered by category of human endeavor. Persons with significant contributions in two of these are listed in both of them, to facilitate easy lookup.

Red Sea

The Red Sea (Arabic: البحر الأحمر) is a seawater inlet of the Indian Ocean, lying between Africa and Asia. The connection to the ocean is in the south through the Bab el Mandeb strait and the Gulf of Aden. To the north lie the Sinai Peninsula, the Gulf of Aqaba, and the Gulf of Suez (leading to the Suez Canal). The Red Sea is a Global 200 ecoregion. The sea is underlain by the Red Sea Rift which is part of the Great Rift Valley.

The Red Sea has a surface area of roughly 438,000 km2 (169,100 mi2), is about 2250 km (1398 mi) long and, at its widest point, 355 km (220.6 mi) wide. It has a maximum depth of 3,040 m (9,970 ft) in the central Suakin Trough, and an average depth of 490 m (1,608 ft). However, there are also extensive shallow shelves, noted for their marine life and corals. The sea is the habitat of over 1,000 invertebrate species, and 200 soft and hard corals. It is the world's northernmost tropical sea.


A reef is a bar of rock, sand, coral or similar material, lying beneath the surface of water.

Many reefs result from natural, abiotic processes—deposition of sand, wave erosion planing down rock outcrops, etc.—but the best known reefs are the coral reefs of tropical waters developed through biotic processes dominated by corals and coralline algae.

Artificial reefs (e.g. shipwrecks) sometimes have a role in enhancing the physical complexity of featureless sand bottoms, in order to attract a diverse assemblage of organisms, especially algae and fish.

Earth's largest reef system is the Great Barrier Reef in Australia, at a length of over 2,300 kilometres (1,400 miles).
