Hello my name is Kyle Im from California USA. While i was calculating my carbon footprint i thought it would be a lot lower then the average person in my area. i found out i was right on everything but one, my carbon emissions for my house where a lot higher then the average. i was shocked but soon realized that we dont have any energy efficient machines in my house.

For this discussion, I shall be tracing the effects of deforestation. First of all, deforestation will, as the term expresses, shall lead to less trees and therefore less CO2 depletion in the atmosphere.
This slight decrease in CO2 depletion leads to more greenhouse gases in the air, which could lead to warmer temperatures. Those warm temperatures can cause certain species on land, who are used to the temperature in the past, to start depleting in population. The ecosystems that have these organisms will have their food chains tweaked to the point of possible species extinction from extinction or scarcity of food source, which could lead to overpopulation of another species which competed against the previously alive species for other resources that are separate from the possibly extinct food source of the now dead species. This dominant species could completely destroy their ecosystem by consuming resources faster than they previously did so due to competition from the now dead species. This could lead to the destruction of the resource in that area and, eventually, the destruction if the whole ecosystem.
Another consequence of CO2 levels being risen is the increase in acidic rain. H2O(water) could interact with CO2(carbon dioxide) and create carbonic acid(acid rain). This acid rain could increase acidity in the soil in which it lands on. Some consequences for this can be seen in the link: (http://soilwater.com.au/bettersoils/module2/2_3.htm.) If the plants in the area where to die because of the acidity, there would be a smaller amount of CO2 consumers AND a decrease in the overall food supply of that ecosystem. Consequences of that are shown in the previous paragraph. Also, if that was the primary food source of the entire ecosystem, then the ecosystem would die in an even simpler way, by lack of food.
Lastly, a consequence of the root of all these problems, deforestation, is what it is going to be used for. If it is used for firewood, firewood converts O2 and some of its carbon atoms into CO2. If it is used for building, it will eventually catch molds that will decompose it into methane and other greenhouse gases. So, in deforestation, both its absence and use create CO2 and/or other greenhouse gases. This is not good, and I would like to say that I am an advocate for the reduction and/or the destruction of deforestation.
Hello, my name is Jeevin Sandhu from Oakland California. After my realization of how much excess carbon is unnecessarily released per capita in California, I tried to look up ways that could be the rational. My findings were shocking.
I found that every year Americans (just American’s alone!) throw away enough paper, cups, forks and spoons to circle the equator of the earth 300 times. In offices in America alone, the average worker throws away 500 disposable cups a year! Imagine how many office workers there are in America. Every year, America uses approximately 102.1 billion plastic bags and most of them end up in landfills. Over 7 billion pounds of PVC are thrown away and only 7 million are recycled. These facts are staggering and almost unrealistic.
I think that education is the key to controlling carbon emissions in the United States. If these astounding facts were presented to the next generation of American’s, there could potentially be a huge difference of carbon emission of future generations. If we present this information, and show the catastrophic results and ramification of our nation and world’s carbon emission change is imminent.
Hello I am Aditya, I am a 9th grader in California. I recently did on online virtual lab about Ocean acidification and I was very surprised with the results. Apparently the CO2 that is released all over the world are being absorbed by the ocean. This higher concentration of carbon in the oceans will cause the pH levels of the oceans to go from 8.8 to 7.6 in just a few years. The higher acids will cause certain animals to die because they can’t be supported. For example sea urchin’s skeletons are made of calcium and the higher acidity causes the sea urchins to have a stunted growth. If the sea urchins die then other species will be affected drastically. Sea otters feed off of urchins and might die out. On the other side urchins feed on sea weed and if there are fewer sea urchins then the growth of sea weed will be uncontrolled. The entire sea ecosystem will be disrupted by the removal of one species.
There are other things that are effected by climate change. I have recently learned about how the increased temperatures are causing glaciers all over the world to melt. The melting glaciers raise the sea level and can cause entire cities to be submerged. Glacier ice is actually the most reflective natural material found on Earth. If the glaciers melt than more energy from the sun will be absorbed resulting in a massive loop. We are at the start of this loop and unless we stop it now we will be caught in the events to follow.
This delicate balance is present in all of the world’s ecosystem. Small things we do right now have effects that we can not fathom. Even the small amount of Carbon Dioxide released by driving to school a cause catastrophic changes to the world. Every person in the globe should realize what it is that they are doing and hoe exactly it affects the world. If we raise the awareness about our current problems then we can change the world one step at a time.
I have read a lot of posts that encourages recycling in order to decrease emissions. Of course, this is a great way to get the most out of our natural resources. Though, I wonder if that is enough. Recycling can take us only so far considering the enormous demand of products we have today. I think that even in a scenario where everything that is produced also gets reused and recycled, the environmental problems will remain. I recently watched a documentary (unfortunately in swedish, http://www.svtplay.se/video/1480596/del-5-av-18 ) that stated that people make a big mistake when not linking emissions and consumption. The documentary spoke of China as an example. It is true that the country has emissions far beyond what is sustainble. At the same time Sweden (where I live) is happy about having managed to decrease the emissions during the past couple of years. What many seem to forget is that countries like China have high emissions only beacuse we want to buy their cheap products. As long as the demand exists the manufacturing will continue. So, reusing and recycling are both great actions, but they should not be the first ones to take. Instead the process should start at the mall or where you buy your electronics. I think the question we all need to pose is: “Do I really need this?”. That way you will both decrease emossions and save money. Another way to do it can be to see if you find what you are looking for in a second hand shop before buying it in the regular store. Analyzing my way of living, I realize that I buy a lot of things that I do not really need.
How about you? What do you buy that you do not really need? And what would you be willing to refrain from in order to lower your global footprint?
Recently, I stumbled upon a Greenpeace article about the effects of deforestation on the environment. Whenever I think of the term “deforestation,” I usually form images of trees being cut down. However, This article gave me an entirely new perspective on deforestation and how serious it really is. It states that when forests are destroyed and burned for human settlements, the carbon dioxide initially absorbed by the trees is released back into the atmosphere. Trees also release methane as they decay. As a result, the production of greenhouse gases from the burning of forests produce as much as “thirty percent of the carbon dioxide added to the atmosphere over the past 150 years.” The increase of greenhouse gases combined with a decrease in the amount of trees to absorb carbon dioxide are even more damaging to the environment.
To ensure that we do not further increase the rate of climate change, we need to plant new forests, moderate the amount of logging, and protect existing forests. We also need to make sure no new forests are cut down. Check out the article below to find out more about deforestation and practices that promote sustainable forestry!
Deforestation is one of the biggest contributors of greenhouse gases in our atmosphere - particularly carbon. When these trees are burned or decomposed carbon is released and levels quickly rise. As stated in the link below, this traps heat and raises temperatures. Not only does deforestation raise global warming levels, but it destroys the home of many animals as well. It also alters weather patterns.
Last year in an environmental science class, I watched a video on forestry practices in Papua New Guinea (can’t link since VHS) that offers a great example of both how and why deforestation occurs and what can be done to stop it while still meeting our need for the resource.
Much of Papua New Guinea’s forests have been stripped away from the land through unsustainable forestry practices such as dragging trees out of forests whole using tractors and trucks and cutting down all the trees in one area, or clear cutting. All the potential profits that could go to the native community for their precious resource ends up going offshore to the greedy industries managing the operations. Furthermore, the loss of trees leads to enormous amounts of soil erosion that in turn causes greater harm to local communities due to the decreased biodiversity from the destruction of habitat. The dragging of trees out of the forest also led to soil compaction that created risk of flooding and less water for the people to use since the soil could no longer absorb water or replenish groundwater. These exemplify some of the most concerning effects of deforestation.
However, there is hope in sustainable forestry practices since they they allow local communities to reap the economic benefits while maintaining the environmental beauty of their forests. Rather than clear cutting and ragging trees out, the foresters selectively cut trees from various areas that can survive losing the specific tree and cut them with a portable saw mill on site before carrying them out of the forest. This ensures the forest remains healthy and supports forest conservation efforts while the community still profits, which also helps the community obtain other economic benefits from the aesthetic aspects of alternative forest products. The link below offers a video looking at some sustainable forestry practices like these that can counter deforestation while still meeting our needs and preventing its devastating effects.
One of the topics that I seem to be hearing about more and more is technology addiction, especially in high school or college students. There have been so many experiments conducted that prove that some people cannot go even five minutes without touching technology in some way. Technology has gone from being a helpful source to being a need in basic everyday life. I also find it quite frightening that technology hasn’t even really been around for more than 15 years now; think about what the world will be like 50 years from now. This also relates to the carbon footprint project because so many people, myself included, are always using technology, not turning their computers off, wanting to buy the newest iPhone or flat-screen TV. I think if there’s any way to lower the carbon amount released by technology, it would be to work harder to stop this technology addiction. Of course, technology can be extremely helpful, but there are also many times when it can be extremely dangerous.
After calculating my carbon footprint, I was shocked to find out that my car traveling made up almost seventy five percent of my overall carbon footprint. Also, According to National Geographic, more than half the air pollution in the United States is caused by vehicles. These greenhouse gases , for example carbon dioxide, are destroying the ozone layer as well as polluting the soil and surface water. Hybrid cars claim to reduce this. The 2011 Toyota Prius hybrid is an example of a popular, affordable hybrid car. However, many question the claims made about hybrid cars. According to a study done by the U.S. Department of Energy’s Argonne National Laboratory, hybrid cars actually require more energy to produce than conventional cars, emitting more greenhouse gases and burning more fossil fuels during the manufacturing process. However, hybrid cars emit much less greenhouse gasses when it is driven as compared to a conventional car. So, this outweighs the amount of energy needed to produce it.
