Negative impact of dams

 Rasmus Svensson

There is around 100,000 dams in America, at least 90,000 of them are dams that are more than 6 feet tall and the rest is small dams. Even though dams can be beneficial for humans, it does not have the same affect on the environment. Although not all dams damage in the same way. There are 4 ways than dams can damage rivers. The first way is that the dams prevent fish to migrate, it means that they limits the fishes to found habitats, food and also escape from predators. The second one is that is slows down the river. A lot of organisms that lives in rivers depends on steady flow to guide them. Third one is that  dams can alter habitat,  which means that they change the way rivers function. It impact the organism that lives there because it gets trap under rocks. The last way is that the dams impact the quality of the water, it changes the temperature of the water, so some spices will get affected and not survive.

    I always considered the benefits of what dams offered to support us with a more carbon free electricity, but never thought about the negatives. This blog just shows me that what humans do always contribute to a environmental imbalance. I wonder how these doms we tragically change animal habitats in the near future.

Land Loss

 Hannah Bailey  There have been posts about sea levels rising however its not just affecting the sea. The water rising is also affecting the land. There is always the conspiracy that Florida will be fully submerged. It is stated on “the travel” page that Florida could be submerged as soon as 2050. This means that section of land will become apart of the sea life ecosystem. All of the oil preserves, the towns, even maybe cars would be submerged and begin to add more pollution to the ocean. This would require the citizens on Florida to have to reside elsewhere. Around 20 square mile of land has been consumed by sea levels rising. That is equivalent to 9,680 football fields of land gone. The image shown is a demonstration of what Florida will begin to look like if we dont take action fast. It is imperative that we save Florida for the citizens, land history, and for the oceans sake.  https://www.thetravel.com/florida-underwater-soon-stats/ https://coast.noaa.gov/digitalcoast...

Wildlife Conservation

  Wildlife conservation is the way of practicing the protection of the animal species and the  habitats they survive in. The Endangered Species Act,  is the establishment and protection of public lands animals live in, and the responsibility of public practices that conserve wild animal populations.  With The earth continuing to grow at a fast rate, it is also meaning that more and more humans are taking up natural resources. This is endangering the existence of animals and their habitats. Programs like the  World Wildlife Fund and  the Wildlife Conservation Society are working every day to slow down the extinction of animals and also protect the earth's biodiversity at the same time.  https://www.nationalgeographic.org/encyclopedia/wildlife-conservation/

Land Reclamation

 Hannah Bailey Land Reclamation  Land is becoming more scarce as humans produce more technology and as the world wide population continues to increase. Land reclamation is "the process of creating new land from the sea." One way of doing this is by placing certain amount of big rocks and cement into a certain location in the water. To fill in between the rocks they place soil and sand until the new manmade land is at its desired height. This benefits the human race by creating land however, how does this impact our waters? How about the sea creatures? Is this damaging the environment? This does impact all of those things. In areas that use have high amount of crab and fish are seeing less and less. The underwater habitats are being destroyed. There was a reclamation project in China that was restricted for the harm against marine life. The picture shown is the progress the China project had before it was prohibited.  https://www.sciencedirect.com/topics/earth-and-planetar...
