Egypt’s future lies in its history, particularly its archaeological history. For hundreds of years the mystery and wonders of the pyramids, the sphinx and the Valley of the Kings have attracted visitors from around the world.

Tourism is the lifeblood of Egypt’s economy and touches the lives of most Egyptians, whether they work as tour guides, restaurant owners, craftsmen or bus operators. Egypt’s history holds the prosperity of the country’s future generations, including that of youths — more than 40 million Egyptians are age 30 or younger — who are seeking opportunities. But thieves are raiding our archaeological sites and selling their findings to the highest bidders.

They are taking advantage of Egypt’s security situation to loot our nation’s economic future and steal from our children.

Egyptians need the people and the government of the United States to support our efforts to combat the systematic and organized looting of our museums and archaeological sites.

Imagine a world in which the stories of King Tut, Cleopatra, Ramesses and others were absent from the collective consciousness. And with much of our history still waiting to be discovered under the sand, the potential losses are staggering.

Antiquities theft is one of the world’s top crimes — after the trafficking of weapons, narcotics and people — but it is seldom addressed. Egyptian antiquities are flooding international markets. Recent auctions at Christie’s in London and New York included several items from Egypt.

Fortunately, when contacted, Christie’s in London withdrew a number of items that had been stolen from the tomb of King Amenhotep III, discovered in 2000 in Luxor. Among the items was a steatite bust of an official dating from 1793 to 1976 B.C.

Although arrests were made in this case, and two auction houses in Jerusalem canceled the sale of 126 antiquities after being contacted by Egyptian officials, the tide unfortunately flows in the other direction.

After being contacted by the Egyptian Foreign Ministry, other auction houses have been unwilling to cooperate with requests to delay or cancel sales of items that experts assess have been stolen. Among those who make their money selling antiquities, cooperation with the Egyptian government has been mixed at best.

Looting is a centuries-old business and a crime that Egyptians will no doubt be fighting for years, especially during difficult economic times. Our country is willing to take a strong stand.

No one can forget the stark images of Egyptians — men and women, Muslims and Christians, young and old — creating a human shield to protect the Egyptian Museum in Cairo during the 2011 revolution. Still, thieves succeeded in stealing several items from its collection.

Despite our government’s best efforts to retrieve those artifacts, more than 50 items, including some from the famous King Tut tomb, remain missing.

In the Aug. 14 attack on the Malawi National Museum, in Minya, more than 1,000 items were taken: statues more than 3,500 years old; jewelry from the time of the ancient Pharaohs; Greco-Roman gold coins. When security forces tried to stop them, the thieves burned some items they could not take, including mummies.

Every day, Egyptians risk their lives to prevent organized gangs from stealing our heritage. Our country is not the only place under attack: Iraq, Syria, Libya, Peru and Guatemala are suffering similar assaults on their heritage. Halting these crimes on our civilization will require a coordinated global effort — from both the “producers” and the “consumers.”

It is our common duty, in Egypt and around the world, to defend our shared heritage. International institutions, governments, business, archaeologists and other experts must come together to explore how to help countries in need protect their treasures.

The efforts of groups such as the International Coalition to Protect Egyptian Antiquities are appreciated — but much more aid is necessary. The youths of Egypt deserve more. There is no time to waste.
