Although it wasn’t until fairly recently that humans have been severely impacted by climate change, the issue was been present for over a hundred years. The first scientist to conclude that burning fossil fuels in the quantity at which we were doing so would eventually result in elevated mean annual global temperature was Swedish scientist Svante Arrhenius in 1896 (Enzler, 2014). In the early 1900s, other scientists believed that the Earth was experiencing global cooling trends until Stephen…

Gas hydrates and more specifically methane hydrates are an untapped source of energy that should be exploited in the coming years. It is widely known humans obtain too much energy from burning fossil fuels. However, this has caused the warming of our planet to accelerate with catastrophic consequences. People have known about the energy capabilities of gas hydrates for some time, but it is not until recently that researchers have begun the process of testing whether it is feasible. Some will…

What type of effect will the removal of the O’Shaughnessy Dam in the Hetch Hetchy Valley of Yosemite National Park have on the environment? The Raker Bill, which eventually became known as the “Raker Act”, authorized the city of San Francisco the right to build a dam in the Hetch Hetchy Valley as a reservoir. It took about ten years to build the O’Shaughnessy Dam and it was completed in 1923. According to the Hetch Hetchy Restoration Study, the dam supplies water for 2.4 million people and…

backbone or spine. Most live on land and they typically give birth to live young. Description of gas exchange: In mammals gas exchange takes place in the lungs. Mammals inhale oxygen though their mouth as part of ventilation and exhales carbon dioxide. The air travels down the trachea before it branches off into the two bronchi. Branching off the bronchi are the bronchioles that transport the air to the alveoli where gas exchange takes place. The alveoli are air sacs. The diaphragm also…

Pollution from vehicles is very harmful to the Earth and the people on it, and has been polluting the Earth for over a hundred years now. We need a way of transportation that’s less harmful to humans and the environment, that doesn’t produce toxic fumes, and costs less money. Battery powered cars are the solution to this problem. Battery powered cars are a safe, non polluting alternative to regular vehicles that burn fossil fuels. Replacing gasoline cars with these non polluting battery powered…

Nobody has an accurate count of the world’s volcanoes, and around fifty to seventy volcanos erupt every year. How do volcanoes affect people and environments? Volcanos around the world affect the environments by making the soil more rich and crops easier to grow, due to the deposits the volcanoes put out. People are also affected by volcanoes by making the environments more beautiful, which causes more tourists to come see the beauty of the land. Volcanoes around the world affect the…

Many colleges and universities have banned the sale and distribution of bottled water on their campuses. Bottled water is allowed on campus, but the institution has decided not to sell or distribute bottled water on campus themselves. Hope College does not have a policy of banning plastic water bottles, however, they should. Plastic water bottles are harmful to the environment, are not as convenient as the free water provided by water fountains on campus, and do not contain better water than…

My best advice for preparing for winter is to plan a trip to escape some of it! I will share one of my favorite places on the planet with you. Georgia O’Keefe’s Ghost Ranch at Abiquiu, New Mexico. I have been there twice. So far. You won’t really be escaping winter there, but the winter you find is likely to be much easier than the one you’ll leave behind. The small town of Abiquiu is located in the mountainous region of northern NM and lies at an elevation of 6378 feet. Scientists…
