Hydroelectricity

is electricity produced from falling water, a renewable energy that keeps the world’s electricity needs in balance. Hydro electricity generated 16.6% of the world’s total electricity and 70% of all renewable electricity in 2016 and is expected to consistently grow throughout the future.

Pros

Canada is the third largest generator of hydropower in the world

Hydroelectricity is one of Ontario’s lead renewable resources, it accounts for more than one-third of Ontario Power Generation’s electricity production, the main advantages of this resource is its low production costs, reliability, flexibility to meet both ongoing base electricity needs and peak demands, and its reliance on water; an indigenous, renewable resource. A few other key pros of this resource is that once the power or electricity is produced the water is returned to its point of origin, making it a very eco-friendly renewable energy resource. Another key pro is the dams consistently and the fact it’s always producing. The dam can be running all day and all night for maximum efficiency and sheer amount of energy processed. Lastly, the dams can shut their flood gates if you will in case of shortage of water or the water being at high demand at that certain time period.

Cons

All of these positives taken into account hydroelectricity does have some negative aspects to take into account. Firstly, Emissions of methane and carbon dioxide. The reservoir of power releases many harmful toxins with the area. This is mostly created from the rotting trees and plants in the drop off point for the water. Secondly, the dam creates a major disturbance of habitat, the creation of the dam alone destroys and cripples many organism’s habitats in the area as well as people having to relocate. Lastly, the creation of the dam can create many agriculture problems, the dam can affect the amount, quality and temperature of water that flow in streams which has drastic effects on agriculture and drinking water.

How it works

Hydroelectric generating stations are in essence factories that convert the energy of falling water into a flow of electrons called electricity. Water at the higher level is collected in the forebay. It flows through the station’s intake into a pipe, called a penstock, which carries it down to a turbine. The turbine is a type of water wheel that is connected to a generator. As the water flows down the penstock the water pressure increases. It is this pressure and flow that causes the turbine to revolve which in turn spins a generator.

Inside the generator are large electromagnets attached to a rotor located within a coil of copper wires called the stator. As the generator rotor spins the magnets a flow of electrons is created in the coils of the stator. This produces electricity that can be stepped up in voltage through the station’s transformers and sent across transmissions lines. The falling water, having served its purpose, exits the generating station through what is called the tailrace, where it rejoins the main stream of the river.

In Conclusion…

Hydroelectricity has many pros that in my opinion weighs outs its cons, the stats that this renewable resource has made make it both efficient as well as eco-friendly which not many other alternative energy sources can say.

Blog Post 3 – Food

 

Like The Roman Empire corruption and greed, will evidently be the destruction to life as we know it. Only this time false hope of a prosperous after life, from a book re-written to serve the needs of religious leaders and hard work, will not save us. Global warming, over population, dirty energy consumption and Genetically modified food, poverty, limited access to water and war are just some of the underlined problems, my generation & future generations are left to deal with; while the individuals who are the root of the some of these issues get richer. The worst part is we can’t escape it, its everywhere….


 

The general public (unless educated on the topic), barley understand what GMO’s are, and the impact on our species health, and the planet we inhabit. Not to mention the other species, that got stuck living on the same rock orbiting the sun, as the cancer known as Man.  G M O stands for, Genetically Modified Organism. What does this mean you ask? Well, its exactly what it sounds like, It’s an organism that has been created by a scientist, by taking some of the DNA from a different organism, to create a unique organism. These Organisms unfortunately are made to suit the needs of the corporations creating them, not the needs of the people who consume them. Anyone who bothers trying to question wither or not these, genetically modified foods are healthy for us or the planet, are just ladled as conspiracy theorists. Even though there is no research that actually proves, these genetically modified foods are at all better, then the lousy not as profitable foods our ancestors have wasted their time growing, and raising for thousands of years before. How foolish. In fact, these man made modified organisms have many cons to one’s health and well-being. As well as environmental risks, and economic concerns.


 

GMO’s have a direct relationship to things like Autism, Birth defects, and many forms of Cancer. Many of GMO’s negative aspects come from the beginning of the process. Crops are first sprayed with a compound called Glyphosate before they are fully grown and modified in the lab. Glyphosate is a herbicide, not a typical spray that kills insects on crops; but a herbicide that is used to kill competing grass, broadleaf and weeds that are near and threatening the Genetically Engineered crop. The compound also is used to speed up plant growth and ripen fruit when its used in its sodium form. Almost all of genetically engineered foods are used in correlation with Glyphosate as a spray, which is very concerning as in 2013 the Environmental Protection Agency increased the allowable limits of Glyphosate in food. While being an herbicide, Glyphosate is also a “mineral chelator” as well as a carcinogen. This means that when sprayed on crops, it immobilizes the nutrients and vitamins of the root plant. Making them not available for your body to consume. Although this is a not a major threat to someone who generally stays away from GMO foods and only consumes them with moderation. Someone who consumes these genetically modified foods on an everyday basis is almost absorbing nothing for their body, and in the process starving their body from vital vitamins and minerals. Which all lead to repercussions for their health and well-being down the line as stated above.

Heres a very informative video on GMO’s and Glyphosate

Blog Post 2 – Population & Sustainability

population-seven-billion-picture-india-crowded-streets

From what we know, Humans have been the most thriving and successful species the planet Earth has ever experienced. Our planet supports millions of different spices, but we are testing its captivity alone. According to Esteban Ortiz-Ospina and Max Roser in “World Population Growth”, The U.N estimates that there are about 7 billion people living on our planet. Ortiz-Ospina & Roser also mention that, 200 years ago there were less then 1 billion. That’s a major gap, most likely the largest gap in population growth ever on our planet. It’s debatable wither or not we are the most intelligent species on the planet, but there are some obvious factors that differ us from the rest. We have the ability to communicate unlike the rest, we walk on 2 legs, we have built huge cities, used natural resources to our advantage to generate power, we grow our own food and raise our own live stock. It only makes sense that we thrive so well, we can live just about anywhere! We live in our temperature controlled homes, drive cars to grocery stores and have access to amazing medical care.

The problem is, every human needs to eat, they need resources from the planet just to survive. Most of us don’t even think about it, and consume far too much. The scary part is, we don’t know what’s the limit. What is the limit of people able to exist on our planet, before we start to run out of basic recourses essential to survival; well no one really knows. Some fear, if we don’t start trying to come up with solutions, future generations won’t be able to stop the enviable.

The Worlds Population problem

Solutions like educating women in third world countries, who don’t have birth control. Also I think we need to empower women in many places of the world, where they don’t even get a say on who they get to have sex with. Most people in more developed countries are actually having a lot less kids then past generations. This allows us to put more effort and recourses in raising our children. Also in the olden days, children were viewed as an extra hand to help make a living; but these days’ majority of parents support their children until they move out. That being said, our advances in technology allows us to live much longer and healthier than our past generations. Another major problem is more times than less, there is never one rout problem. Chances are there is a numerous amounts of issues, then just one bold issue. What I mean by this is there, are some many issues with our planet. We are the worst issue; we are like a cancer that plagues this planet. Unfortunately, I don’t think there is a real solution, other than change the way we live completely. That’s not even realistic either, so I guess maybe the only real solution for this planet to get healthy again. Sadly, is if we go. Without humans I think the planet and majority of the species would thrive and be thankful we are gone.
