Are dams good or bad-Ryan Wilburn

Are dams good or bad?

The good side to dams are that they provide energy, drinking water, flood control, and recreation. Dams are engineered structures meaning they make our life high quality. About 3% of the dams in the United States produce energy and the largest renewable energy. 

The bad side to dams are that they are very expensive and have a lot of hard to keep them up and running. In the article, it talks about that dams are meant to fail. The reason is because they lose reservoirs and the dams collapses.

So you pick if they are good or bad?

Fracking and natural gases 3

Fracking is using water, chemicals, and sand to bust shale and bedrock to release gas and oil. It is beneficial and helpful to creating jobs but harmful to the environment. Fracking releases some oils and gas into the water reservoirs underground which actually could lead to flammable water which is for obvious reasons is harmful. However economically it creates so many jobs in chemical engineering and mechanical engineering to create the equipment and everything for the job.

Post 5: Why Animals are Important Resources- Emilia Schleper

Animals as Resources 

Humans often take advantage of our animal resources, by mistreating or causing harm to them. Animals are a large source of food for people and they also supply us with furs and other animal based products like leather. Society only cares about the animals seen as pet such as cats and dogs, the ones we like to see happy and healthy. Often forgetting animals similar to, but not limited to pigs, cows, horses, goats and sheep. These animals regularly face cruelty and suffering, but society only worries about any “unnecessary” cruelty. I see no difference between unnecessary cruelty and cruelty, they are actually the same thing only to a different extent or cruelty. There are many more humane ways to raise and treat or slaughter animals, but it is usually more expensive and/or time consuming for farmers. Here in the U.S. it is illegal to slaughter horses for human food but not animal food. We as a society place our desires over the needs of these animals. We view these animals as not having consciousness or feelings because they do not have the same cognitive abilities humans possess. We often over work and breed animals to meet the demands of society.

Time is running out for sand blog 4

Time is running out for sand

Sand and gravel are being used and extracted a lot faster then it can be replaced as of now. Sand is one of the key ingredient of modern life but yet no one knows how much is being mined and how much of it is left. From the glass bottle you drink from to the computer you work, sand is there. Their is about 32-50 billion tones of sand used each year, mainly for the use of concrete, glass and electronics. As of right now China, India and Africa are the ones that are in demand for sand. Mining speeds up the process of erosion as you can see with the picture I am showing. If we are not careful, it can get worse. -Ryan Wilburn

The Impact of the Fishing Industry

      In this article, I learned that over fishing is a huge problem that we currently have and it contributes to a lot of our pollution. I had no idea that 'over fishing' was a thing and some of the methods that the article talks about that people/companies use to fish honestly blew my mind away.
    First of all, over fishing is the removal of fish at a huge rate to the point that the species cannot 'replenish' themselves in time. This obviously leads to a bunch of problems in our world's ecosystem, and that's why it affects us so much. As the article said, the fishing industry affects a lot of marine conservation issues. Some of these include fish population, water pollution, and a thing called habitat degradation. One of the ways that mass fishing happen sis by "netting". This is when a fisherman literally drags a huge net across the bed of the ocean floor. This destroys the coral reefs that are sometimes on the sea floor. The coral reef is home to many different kinds of species and is an essential part of the ocean. Another way that over fishing occurs is by using explosions. This kills fish underwater but also pollutes the ocean.
     This is an important topic that I personally think we should all know about. We don't really think about it when we enjoy our seafood, because I certainly don't, but we should know about how we are receiving our food and where it comes from and how it can affect our world.

Post 4 Endangered Animals- Emilia Schleper

Endangered Animals

     Our planet now has 41,415 different species of animals and plants on its endangered list, almost 16,306 of those species are threatened with extinction. We are in the middle of the earths sixth mass extinction, the last one took place over 65 million years ago. This extinction is caused almost entirely because of humans and our extensive use of our natural resources. Nature simply can’t support the pressure we put on the environment. We have over hunted, farmed, and industrialized our planet. Our population goes unchecked, growing at an unsustainable rate for the Earth to keep up with. The human population is at the top of the food chain, giving us the chance to over populate the earth. The human races overconsumption of Earths resources often disrupts numerous ecosystems in many ways. We often destroy their habitats with our pollution, deforestation, agriculture and industrialization.
     There have been many treaties and laws put into action to try and slow the decline of these species. Theses laws make it illegal to harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect any of the species on the list. Although these species are still endangered they are still considered valuable buy people all over the globe who purchase them for the products they make.
