Alexandria and the Nile River Delta: data between 2005-2020. Cairo currently has 22 million people while Egypt's growing population is 85 million with most people living very near the Nile River, including in the city of Alexandria. The Egyptian government has ambitious plans to move many people from the rich agricultural land along the river to planned cities in the neighboring deserts. Egypt's population is set to increase to 107 million by 2035, so pollution is likely to continue to be a serious and growing problem.
