Landfill systems

 Hannah Bailey 

In my previous blog I wrote about the different kind of waste disposals and how they affect the environment. It was portrayed that landfills was a not environmentally friendly. Let’s find out why or why not. According to department of health and environmental control(DHEC), landfills are way to expensive to be called a dump. How a Class 3 landfill works is that the waste is placed in a cell located in a specific section in the landfill. Then a compactor comes and crush the waste down in order to safe space. As the Cell is being filled, a new cell is being created. It is rare to have more then one cell being filled at the same time. Once the cell is full they covered it with soil. This can raise the question of what is the waste doing to the environment? The landfill uses a lot of systems to protect the environment as much as possible. The bottom liner system is used in order to prevent the environment from coming in contact with any waste. There is also a system that collects water that may happen to fall on the landfill. This is called the storm water drainage system. The pipes take the collected water to a retention pond. It is stated “ this water has not come into contact with the waste.” The methane collection system is self explanatory. This system collects the gas during the wastes process of decomposition. This system is very important to the landfill because methane is a lethal gas that can explode. After the methane is collected it is used for energy. In this case, class 3 landfills is using our waste that cant be recycled and using the greenhouse gas for energy. Do you think landfills are environmentally safe?

    interesting. Efficient methane collection is huge progress, since methane is so potent a greenhouse gas.

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...
