Reading and thinking to get the text for numbers, circle the numbers and guess what they mean from problems to solutions. economic development is necessary if we want to improve society. There comes a time when the old must give way to the new, and IT is not possible to preserve everything from our past. As we move towards the future, finding and keeping the right baLance between progress and the protection of cultural sites can be a big chAllenge. Big chAllenges, however, can sometimes lead to great solutions. In the nineteen fifties, the egyptian government wanted to build a new damn across the nail in order to control floods, reduce electricity and supply water to more farmers in the area. But the proposal LED to protests. Water from the damn would likely damage a number of temples and destroy cultural relic that were an important part of egypt cultural heritage. After listening to the scientists who had studied the problem and citizens who lived near the damn, the government turned to the united nations for help. In nineteen and fifty nine, a committee was established to limit damage to the egyptian buildings and prevent the loss of cultural relic. The group asked for contributions from different departments and raised funds within the international community. Experts investigated the issue, conducted several tests, and then made a proposal for how the buildings could be saved. Finally, a document was signed, and the work began in nineteen sixty. The project brought together government's and environmentalists from around the world. Temples and other cultural sites were taken down peace by peace, and then moved and put together again in a place where they were safe from the water. In one hundred and sixty one, german engineers moved the first temple. Over the next twenty years, thousands of engineers and workers rescue twenty two temples and countless cultural relic. Fifty countries donated nearly eighty million dollars to the project. When the project ended in ninety eighty, IT was considered a great success. Not only had the countries found a path to the future that did not run over the redick of the past, but they had also learned that this was possible for countries to work together to build a Better tomorrow. The spirit of the a swan damp project is still alive today. Perhaps the best example is shown by UNO, which runs a program that prevents world cultural heritage age sites around the world from if a problem seems too difficult for a single nation, the global community can sometimes provide a solution.
