2A-DAM CON ﻿ STRUCTION

Dams are not a joking matter. There can be many problems such as economic security, public safety, water storage efficiency, flood management, job creation, recreation, and adaptation to climate change all effected by dams. The United States have been trying to export technology and skills, but with the high demand, China, Russia, and India are the highest. Most dams are in these locations. Dams lie where evaporation rates are high. We the United States regulate irrigation dams differently from navigation dams. Navigation dams are a structure design that raises the level or increases the depth to navigate the dam. If a company owns two dams that are down the same stream they are subject to different environmental laws. The United States once was the leader of all the world, in the construction of dams, but as time went on it has decreased. Did you know that there are about 40,000 large dams which can measure more than 15 meters in height, are currently obstructing the world's rivers? Some of these reservoirs cover more than 400,000 square kilometers of land this is larger than the combination of the United Kingdom, Belgium, The Netherlands and Austria! You can never have a certain amount of dams, but rather we all need healthier rivers, safer societies, and a more efficient water-development. This all takes more then just one person to make these kinds of changes; us as human beings on Earth need to form together and make these changes to help with dam construction and make it better for everyone to live in a happier Earth.

**Dams Cause Deforestation**
Dams not only effect forest loss, but it also can effect the major environmental changes on local people. These dam sites can cause an impact on an entire river basin. Not only for the best agricultural soils that could cause floods by the reservoir, but major changes can occur in the environment surroundings. At the same time, Dams have a number of health hazards, such as diseases that can be introduced by the thousands of workers that are brought in to contruct the dam these may include AIDS, syphilis, tuberculosis, measles and many other kinds that are not known to the environment. All of these kinds of illness were never there until humans came in and effected the locals. __[]__

Dam construction causes deforestation, and deforestation causes:

 * ======**Effect of destroying aquatic habitats and affecting fish populations, displacing indigenous peoples, and adding carbon to the atmosphere**======
 * **Erosion resulting from deforestation, causes the dams to be inefficient.**
 * **Reduced water flow downstream disturbs riverbeds and affects floodplain farmers who rely on seasonal floods for nutrients to enrich the soil and kill pests, forcing them to turn to** **pesticides, further effecting the environment. ﻿ **
 * **Organic matter decays slowly in tropical waters, consuming much oxygen. When dams inundate forest areas, the dead plants may not decay for centuries, resulting in oxygen-deprived water and high acidity.**

We know that by affecting one thing in nature, we cause a ripple effect; so, now not only are we cutting down a forest, but we are cutting down homes, and we are cutting down species.

__** The Pink River Dolphin ﻿( **__ Amazonian River Dolphin)


Pink Amazonian River Dolphins face extinction. **Why?** Loss of food, and polluted waters. As said before, organic matter decays slowly in tropical waters, dams cause more flooding which leads to more organic matter to be decayed than would in the natural cycle. So now, the fish in these waters have lower oxygen and high acidity. Fish are dying off, so now the dolphins have more competition.

There is hope for these animals thanks to the non-profit International Society for the Preservation of the Tropical Rainforest (ISPTR), whose first globally known project PARD, the Preservation of the Amazonian River Dolphin. __[]__



=Paddlefish=

Endangered

Paddlefish are a species older than dinosaurs. They can live in the Missouri and lower Yellowstone River’s roiling waters. These odd looking fish feeding on microscopic zooplankton and filtering water through their gill rakers. They have

These fish are not closely related to sharks. These fish are known to be found only from the Yangtze River in China. And the American Paddlefish can be found in the Mississippi River.
Paddlefish lay their eggs in midstream over bare rocks or gravel. The eggs are sticky so they adhere to the rocky substrate. The young are swept downstream after hatching and grow to adulthood in deep freshwater pools. Which this makes it important to not produce dams. This all can reduce the population if the baby fish are not able to swim down stream or be able to hatch correctly if there is a dam at the end of there journey or being built.

**The best way for us to help with Dam Conservation is by using water efficiently.**

 * Water conservation is the most cost-effective and the most environmentally sound way to reduce our demand for water

//You can Help with the conservation of water in your everyday life!//

Make sure your toilet is an ultra-low flush model, which uses only one and a half gallons per flush.

<span style="background-color: transparent; color: #000000; display: block; font-family: 'Times New Roman'; font-size: 16px; text-align: left; text-decoration: none;">2. If you're taking a shower, don't waste cold water while waiting for hot water to reach the shower head. Catch that water in a container to use on your outside plants or to flush your toilet. Saves 200 to 300 gallons a month.

<span style="background-color: transparent; color: #000000; display: block; font-family: 'Times New Roman'; font-size: 16px; text-align: left; text-decoration: none;">3. Check toilet for leaks. Put dye tablets or food coloring into the tank. If color appears in the bowl without flushing, there's a leak that should be repaired. Saves 400 gallons a month.

<span style="background-color: transparent; color: #000000; display: block; font-family: 'Times New Roman'; font-size: 16px; text-align: left; text-decoration: none;">4. Turn off the water while brushing your teeth. Saves three gallons each day.

Put a layer of mulch around trees and plants. Chunks of bark, peat moss or gravel slows down evaporation. Saves 750 to 1,500 gallons a month.

<span style="background-color: transparent; color: #000000; display: block; font-family: 'Times New Roman'; font-size: 16px; text-align: left; text-decoration: none;">2. If you have a pool, use a pool cover to cut down on evaporation. It will also keep your pool cleaner and reduce the need to add chemicals. Saves 1,000 gallons a month.

<span style="background-color: transparent; color: #000000; display: block; font-family: 'Times New Roman'; font-size: 16px; text-align: left; text-decoration: none;">3. Water during the cool parts of the day. Early morning is better than dusk since it helps prevent the growth of fungus. Saves 300 gallons.

<span style="background-color: transparent; color: #000000; display: block; font-family: 'Times New Roman'; font-size: 16px; text-align: left; text-decoration: none;">4. Don't water the lawn on windy days. There's too much evaporation. Can waste up to 300 gallons in one watering. <span style="background-color: transparent; color: #0066cc; display: block; font-family: Times New Roman; font-size: 16px; text-align: left;"> <span style="background-color: transparent; color: #000000; display: block; font-family: 'Times New Roman'; font-size: 16px; text-align: left; text-decoration: none;">(This Information is from <span style="background-color: transparent; color: #800080; font-family: Times New Roman; font-size: 16px; text-align: left;">__[]__ )

We all breathe the same air no matter what location of the world we live in. Your company has an impact on this world. Your Dam Construction has an impact on the rainforest, and I have a concern about it. I have looked up my facts and done my research. Conservation is an issue that happens every single day. Dam Construction destroys aquatic habitats and has an impact on fish populations and adding carbon to the atmosphere. Deforestation is the biggest issue when it comes to construction of dams. Cutting down trees causes erosion which is inefficient to produce a dam. What has the impact on our race would be ourselves. As we go into rainforest that have cultures that are not in contact with the kind of illness that we may carry, thousands of people die from the lack of medication they posses. We have all this free range medications that we can access but in the rainforest the people that live there are not. They have to make their own meditiation. If WE don't go into their rainforest and cut down tree to produce dams that are unneeded, then the world can be a safer environment for everyone. Dam Construction is a preventable cause that many people tend to overlook. Everyday, at any given time, it seems that another form of aquatic life or a habitat is damaged or destroyed by what is allowed through Dam Construction. As a student, along with a concerned member of society, it is in my best interest to inform you of the harm that you are causing with your company. The Barnard Construction Company, builds and constructs the harmful and destructive dams that are damaging our rainforest. It may not be of much concern to you, but as a supporting student, its in my best interest to try and put a stop to what is causing such deforestation. ** <span style="background-color: transparent; color: #000000; display: block; font-family: 'Times New Roman'; font-size: 16px; text-align: left; text-decoration: none;">Sincerely, <span style="background-color: transparent; color: #000000; display: block; font-family: 'Times New Roman'; font-size: 16px; text-align: left; text-decoration: none;">Shannon Frias Kristen Torres Aaliyah Brodeur
