Rivers-Streams+Conservation


 * 1) ** **What is the Human Impact on Rivers and Streams?**

**a) ****Positive-** The Clean Water Act of 1977. This is the primary federal law governing water pollution. Also known as CWA (clean water act). This law protects bodies of water from toxic substances being dumped into them. This will hopefully ensure that surface waters will meet standards necessary for human sports, and recreation. Also a requirement of the 1987 Water Quality Act states that all states must develop strategies for toxic cleanup.



**b) ** **Negative-** The abuse of waste through channelization (especially in Europe, North America and Asia), has led to the loss of the original form of the rivers and streams. Trash, litter, and garbage often ends up in these surface waters. because surface waters collect in low-Lying areas, anything that is dropped or blown into watershed can eventually reach a drainagway. In urban areas, trash and litter often are transported by stormwater runoff. Regardless of source or type, trash is a form of water pollution.



**2) ** **What are the problems in Rivers and Streams that need to be addressed by humans?**

==== **a) Problem 1: **Dams, they may help stop pollution, and flooding, but they do wonders on the ecosystem. In natural un-dammed rivers, the river water is well mixed and full of oxygen. Though in a dammed river the water begins to stratify, which means that the cold water sinks and the warm water rises. At the bottom the water is high inorganic matter, high in salanity, and very low in oxygen. Also in normal rivers, habitats for many Anadromus Fish, such as the Pacific Salmon, and are vital to their survival. In dammed rivers, Anadromus fish face more challenges on their way up-stream, and many species have become threatened or endangered. ==== ====

**b) Problem 2: ** Heavy metal pollution is a quickly growing problem for our rivers, streams, and ponds. Heavy metal pollution is a threat to human health, animals, plants, and the planet itself, and is mainly caused by industrialization. While some of the metal pollutants come from fertilizers and sewage, the biggest source of heavy metal pollution definitely is industrialization. Clean water is our step into a clean future. Our sollution is using less Mercury, Aluminum, Zinc , Lead, Cadmium.
