Recycle the Present, Save the Future: Effects of Recycling Approximately 99% of all soda cans are solely made of aluminum; because of this it is highly important that we recycle. Additionally, more than 80 billion aluminum cans are used in the United States every year. Aluminum recycling can have disastrous effects; everyone should be required to recycle it because it is a big factor involved with saving our Earth. There are many metals in the world that aren’t nearly as used as aluminum so it isn’t as imperative that they are recycled, but with this world wide used metal we must take a stand. It can take from 80 – 200 years for an aluminum can to decompose when left in the earth and this adds up quickly due to the large number of cans used each year.
The idea that the climate had changed and ended dinosaurs as we know it is a bit hard to grasp. All throughout time species and organisms evolve; they adapt to their surroundings. Who’s to say dinosaurs didn’t? Some scientist say “Dinosaurs may have been partly to blame for the climate change. Their diets meant they emitted vast clouds of Methane, a powerful globe warming gas” (Leake) and that a normal dinosaur of that era could easily produce a thousand liters of methane a day.
This means that humans -- our kind of humans -- have walked the planet for four thousandths of a percent of the Earth's history. To suppose that humans can so easily damage a planet that got along just fine without them seems both unlikely and conceited. The earth, with all its atomosphere, microbial life, and water, provide a way for the planet to heal itself, so to speak, from humanity's actions. The earth doesn't care what actions we take on a daily basis -- it has been around vastly longer than any living thing. In his 1996 book Pale Blue Do... ... middle of paper ... ...rly fight our “gut feeling” and restore proper reasoning.
Not a surprise, since fossil fuels were the main source of global energy at the time, and still are. Science proposed many a solution to the problem, but it seemed the most practical thing to do was to conserve fossil fuels by replacing them with a renewable fuel of some kind. As a result, many different kinds of clean, renewable fuel were discovered or invented, then put into use all over the world. This is where most of our ideas of alternative fuels today came from. However, in more recent times, scientists have discovered that the total amount of fossil fuels left on Earth is still quite plentiful, enough to last a few hundred more years or so at the rate they were using them in the 60’s and 70’s (Sustainable).
The earth has proven overtime that it will balance itself out. We are able to see that greenhouse gases were 10 times higher now than they were 500 million years ago. So why do we need electric cars, contraception controls or food and water restrictions. We have the ability to harvest salt water to make fresh water combating limited water resources and can sustain life on none natural food products. Certain people still believe that life is all about taking whatever is needed in their lifetime regardless of the economic and environmental consequences.
If governments do not change quickly enough, sooner or later the world will become uninhabitable. Fossil fuels are the buried remains of animal feces and plants. These remains and plants have been in the ground for millions of years and from the pressure in the ground, they have been converted into the sources of energy that are used today. Fossil fuels originated from the Dinosaur Era hundreds of millions of years ago. Although, fossil fuels may give off billions of tons of carbon emissions each year, it is still used because it is the easiest energy source that is extractable and usable today.
Coal is the most widely used fossil fuel on Earth but it is all but certain it will ‘run out of stock’ in around 45 years. This is just one example that shows how these non-renewable sources of energy that take over billions of years to form cannot be sustained in the near future unless society turns to cleaner renewable energy resources that may just save the Earth as we know it. If humans do not realize how harmful these fossil fuels are (and have been for years) to the world soon, then the effects could be irreparable and humans could be stuck on a planet surrounded by... ... middle of paper ... ...rth. In fact, it actually produces ten percent of the United States’ energy (Duncan 212; Davis 212). As has been noted, renewable energy resources can seriously impact society as a whole and provide for a safer and cleaner environment.
Pre-Agricultural Human Environmental Impact In the two million years it is believed that humans have populated the Earth, they have displayed the remarkable ability to adapt to any environment. Archaeological evidence has proven that the earliest humans were able to occupy and control every terrestrial ecosystem on the planet. Human impact on the environment has increased progressively through time from the earliest hominid hunters to modern city-dwellers. A fundamental expression of early humanities ability to control the environment occurred during the birth of agriculture. While the ecological impact from this feat has allowed humanity increased control over its environment, the earliest hominids were able to survive nearly two million years without this invention.

Automatic controls should have been extended to almost all areas of maintaining normal operational limitations, especially with the quality of the scientist around Chernobyl. Izmailov, a veteran of Glavatomenergo, said “It was practically impossible for us to find anyone in the central directorate who knew much about reactors and nuclear physics. At the same time, however, the bookkeeping, supply, and planning department grew to an incredible size.” While it may be a bit of an exaggeration, the fact still stands that under such incompetence, it would have made logical sense to have the majority of safety and maintenance carried out through an automated system.
This essay is going to bring to light why the NASA budget, instead of being cut, should be increased. The most common misconception people have is that NASA doesn’t really do anything for us anymore. Completely to the contrary; NASA is like a plant. Just like a plant takes in CO2 then puts out life giving oxygen as a byproduct, so does NASA take in existing “primitive” technology and world issues and put out life saving applications as a by-product. If anyone has been alive anytime after 1958 you have benefited from at least 30 of NASA’s 30,000 different applications.
