The Comparing and Contrasting of Snails of the The Nile River is a river that winds through Africa into the Mediterranean Sea. The Nile River is considered to be the river of life for both people and wildlife. People who live along the river have the highest rate of bladder cancer. The Schistosoma Haematobium or blood fluke, which is carried by a snail called the Bulinus Truncatus, infects many people who live along the river. There is a parasitic worm which burrows into blood vessels of the human bladder. The Aswan High dam was built in the mid 1950s...
was an increase in the amount of snails. A third similarity is the increase in vegetation which means an increase in food for the snails. The last similarity is that the snails carry the blood fluke.

These are the differences between above and below the dam. One difference is the water. As the water got higher more plants grew and snails came because the hippos left. A second difference is the canals. The canals slow the water and more plants can grow.

The question remains as to whether the dam improved the life of the people along the Nile River.
