You all have probably heard that carbon is released from cars, but have you ever wondered just how much is released? It may be more than you expect. According to the United States Environmental Protection Agency, 8,887 grams of carbon dioxide are released from just one gallon of gasoline. It takes on average about 16 gallons to fill up one car’s tank. This is a lot of carbon dioxide that is being released into the atmosphere. Luckily there are ways to reduce the carbon dioxide in the air. One of these ways is gasoline made from carbon dioxide. Researchers at the University of California San Diego (USCD) recently showed that, “light absorbed and converted into electricity by a silicon electrode can help drive a reaction that converts carbon dioxide into carbon monoxide and oxygen (www.technologyreview.com).” Carbon monoxide is a key ingredient in making synthetic fuels such as gasoline. With this process, using carbon dioxide to produce carbon monoxide, the carbon in the atmosphere will be able to be recycled. Thankfully, this is part of a movement to find logical ways to use carbon dioxide, a huge greenhouse gas contributor. Sadly, this type of gasoline probably won’t be on the market for at least the next ten years.

There are certainly a lot of widespread effects of climate change on the ocean and three include a darkening of ocean water, an increase in sunlight affecting shallow coastal regions, and the possible end of thermohaline circulation.
The first two of these effects I recently read about at the first link listed below, which details five unexpected consequences of climate change. Since precipitation will increase in many areas of the world as a result of global warming (the warmer air will hold and eventually release the excess water evaporating in higher levels of precipitation), there will be an increase in river runoff that will knock loose more sediment to deposit into the oceans. This is a major issue, as it will lead to cloudier water that is more opaque and will drastically alter regional ecosystems. In fact, the early consequences of this have already been seen off the coast of Norway, which has seen a decrease in biodiversity as excess sediments in its waters have given rise to an increase in its jellyfish population.
The second consequence will arise in regions around glaciers. As rising temperatures in climate change melt glaciers, shallow areas underneath the ice at the poles of the planet will be bathed in sunlight and that will drastically alter those ecosystems by allowing algae and other such species to overrun vertebrates and deplete biodiversity. In both regions near areas of river runoff and near glacial areas of the poles, biodiversity is and will be seriously impacted by climate change.
The last effect of climate change I referenced is the stopping of thermohaline circulation, which I learned about last year in my environmental science class. Thermohaline circulation is essentially the cycling of nutrients and ocean water. Water gets saltier, or denser, as it moves toward the north pole due to a combination of recent evaporation in warm areas, which causes there to be a higher concentration of salt, and the overall cooling of the water in general, which makes the water molecules more compact due to less energy. This colder, denser water becomes so cold and dense as it moves more northward that it eventually sinks. By sinking it drives a major oceanic pump, which is essentially a current of water in which that cold, dense sinking water drives the movement of water along the ocean floor until warmer, less dense water rises at upwelling zones. These upwelling zones reside on west coasts such as that of Western Europe and are vital as they bring nutrients to ecosystems and help regulate temperatures. Climate change threatens this vital pump since melting ice off the coast of Greenland dilutes the water and salt mixture of the ocean in the north. As it becomes diluted, the lower concentration of salt decreases the water’s density. If climate change continues on its current path, the water’s salt concentration and thus its density will decrease so much that the water may not sink anymore and the major oceanic pump could stop. This would have detrimental effects for ecosystems and the entire ocean and they both rely on the nutrients, fishing industries, and people in areas on the western coasts that rely on this temperature stabilization. The second link below has a great summary of thermohaline circulation as well as the effects of climate change on this important circulating tool.
Hi im cole and I live in the US. I agree with Evan that the US does pollute and destroy the earth a lot(even though they have acts and laws that they have been put in place to protect and save our earth) and that each person can use less harmful materials. I believe that each and every person should do something or change something in their life so that the Earth benefits from it. the only thing is that we humans are always looking for a better quality life, and in that search we tend to overuse and abuse our finite environment. So its up to us to figure out the balance between human health(quality of life) and the environment.
Hello everyone! I am Evan and I am from the United States. I feel like out of all the nations, America produces the most pollution and destroys the environment the most. I think we all can produce less pollution by using less energy consuming products and switch to more energy efficient resources. If we do this we can greatly affect the environment we live in and make a greener planet.
Hi everyone, I’m Jocelyn. I lived it Taipei, Taiwan. I’m studying at Dominican International School. In Taiwan, we have a law that you cannot simply throw the chemical waste into the river or sea, which will pollute the water, and also effect the environment, or you will need to pay some money for that. Also, people in Taiwan support recycle very well, we usually separate the trash into three main category: paper, aluminum can and glass, plastics, and others, and that’s a good thing that the people from the other country should do it too. But, there is another thing that I think the government should change, and stringent the laws. Taiwanese really love dogs, almost every family they had a dog, but, many people are not responsible for their dog’s faeces, whenever their dogs wanted to “go to the toilet”, they’ll just bring them to the street and let them “do it” there without cleaning up, that makes the environment become stinky.
Everyone is responsible for protecting the environment. We can choose to live in a healthy and comfortable environment, if we want to. Just do it!!! What are you waiting for? Take action now!
Hi, I’m Eve, and come to speak of the environment, this is an issue that concerns many people, especially ongs and organizations, such as Greenpeace, Green Action, Edane, etc. struggling to improve our planet, fight:
+ against deforestation
+ to prevent the extinction of many species, both animals and plants.
And although such organizations exist, we can all put something of interest for our environment, and help keep it with small gestures, such as recycling paper, glass, organic products .. We can also use different light bulbs, consuming organic products, indigenous and seasonal, and multiple ideas more.
What savemos of our planet, based on the environment, there is still more than a small part given the atrocities committed incuviertamente, a clear example is this video, this is not just a music video, and was prohibited Published by the images it contained and displayed to the public, completely real.
please someone can answer me? telling his opinion on the environment? thank you very much.
During ww2 when the petrol was rationed the health of Swedish citizens increased. Because they couldn’t use their cars they had to walk or go by bike instead, and that really increased the health of Swedish citizens. I am not saying that we should ration petrol again but we should think of that if we go back to basics (more natural exercise, ecological food etc.) it doesn’t just help the environment but our bodies as well. In a time were people die from being too fat we should really think about these easy steps to be healthier. An idea could be that instead of giving children a public transportation card or have school busses they could be given bikes to go to school with together.
Hi again! I am a high school cross country cross country runner and I run anywhere from 4-12 miles a day. I’ve found that I prefer running on trails and in parks to cities and sidewalks. For a while I thought that it was the softer impact and the more peaceful environment, but the other day I was running down a fairly busy street, I realized how my breathing was heavier than usual. Running around towns is significantly more harder on my lungs than running in parks. The emissions from cars, stores, gas stations, etc really do effect me in a negative way-no wonder I prefer the trails!
This leads me the interesting problem I wanted to point out: as “smog centers” expand and air pollution increases around the world, runners, cyclists and outdoor enthusiasts are at a greater risk being exposed to air pollution. It is unfortunate, an frankly unfair dilemma to put at risk those who are working their bodies, promoting a healthy lifestyle, and strengthening bones, muscles, joints. Have we done so much damage to our environment that healthy habits have become unsafe?
