Julia W-USA, Oct. 17, 2013

My name is Julia and I live in California. According to my newfound research, my home energy is also a major contributor to the total amount of CO2 released. 3263 kg of light energy leads to increase my carbon footprint, so a good 142 hours of light are being used on an average daily basis. All this CO2 is being released from a single house. So in this entire world, think about how many houses and apartments there are. Millions. Every single amount of light emitted contributes to a increasingly high carbon footprint.
We could definitely reduce the carbon footprint regarding light energy by simply turning off the lights more frequently. It’s not as if there are people present in every single room where the lights are needed. Lights are unnecessary when unused, which they often are as they’re forgotten to be turned off. When you’re looking for lightbulbs, people may not realize the great effect a different light bulb may make. Fluorescent bulbs are the most prevalent energy efficient bulb that are available today. They consume an average of 75% less electricity than incandescent lights. Switching to energy efficient lighting represents a great opportunity to reduce your carbon footprint and help save money for you electricity bill. From now on, I will try to remember to turn off the lights after I leave a room. That way I won’t let the light sit there for hours wasting up the energy and giving off carbon. I will also try to buy more fluorescent bulbs, when we need to replace old ones. Those bulbs are able to save more energy and consume less electricity. Next time, I decide to test and see how much my carbon footprint really is, I know that I’ll see a difference in the home energy section.

    I have this same problem! Leaving lights on is a bad habit of mine and I have been more careful about turning them off when I'm not in the room or if they are no use to me. My parents already noticed a difference in the past couple of weeks and went out to get the fluorescent light bulbs so if they do get left on they still are better for the earth.

    Hi Julia, i also have these bad habits of leaving the lights on and i agree that it is a easy and simple way of reducing the amount of CO2 released. Another bad habit i have is turning on the lights when it is still light out side and that adds to the reason why my light energy use had such a big impact on my carbon foot print. After reading your post i came to the realization of that most of the light bulbs in my house are not fluorescent and that is an easy thing i can change in my household to save more and consume less energy!

Discussions Discussion Carbon Footprint: Family
Ethan M - United States, Oct. 17, 2013

Hi, I’m a student from US. Our school/class recently did an assignment to find out our carbon footprints, and I was absolutely astonished at how high mine is! Before this, I have always thought that my family produces very little considering how conservative we are in our lights.. It turns out that I produce a little more than the average :(. I never expected that food and bath/showers would have such a major effect. After learning about the bad contributions I’m making to society and the world, my number priority currently is to 1. Take efficient showers 2. Eat better 3. Walk more. Anything else I could do to drastically decrease my carbon footprint?

    Our class recently did the carbon footprint challenge and I too was shocked to see how high mine was! I myself am not very efficient at turning off lights after leaving a room so I understand why my home energy was fairly high, but I usually am very good with carpooling so I was surprised at how high my amount of CO2 released from transportation was. My food CO2 release was fairly high as well because of the amount of plastic bags we get from grocery stores. Having a big family, we need a lot of groceries.
    In the future, I'm going to turn off lights in rooms when I leave them, walk where ever I can, and reuse plastic bags or change to paper. You could also get fluorescent light bulbs as they save more energy than incandescent light bulbs. Another way you could decrease your carbon footprint is composting and recycling as much as you can. I know I'm going to try all that I can to decrease my carbon footprint and I hope you do too.

After taking the carbon footprint challenge, I was both horrified and pleased with the results. My home carbon footprint was far below average, as was my purchases’. My food category was just a tad below my region’s average, but nothing spectacular. However, my transportation footprint was astonishing. The average for my region was about 8000 pounds per year (about 3600 kg), but my footprint was about 32000 pounds (about 14000 kg)! This number blew me away, as I usually pride myself on being somewhat environmentally thrifty. That’s what 3 round trip flights, one of which was international, and a drive 550 miles away will do for you, I guess. However, I’m all-around pleased with my footprint, as this massive amount of traveling will definitely NOT be a habit of my family’s. I’m happy as long as my 3 other categories are kept in check as they are now. However, I’m not willing to alter the amount of traveling I do (although I doubt I will ever do quite as much as I’ve done in the past year), which is why I posted this in the Off the Table section.

    Hi Eric! I completely agree with you because I was shocked with my results even though I accidentally 20,000 miles instead of 10,000 for the car transportation but still I came shockingly above everyone in the US even without my huge mistake! But even though I was above everyone in the US I was surprised to see that everyone I had outnumbered with my transportation was far above people in other countries! Also, I went to Norway in the summer and of course I was above most people due to that. I was surprised by how low my technology use was because I feel like I'm always on technology even though I never have time due to homework! The results were very Very surprising.
  • Haley Brown Haley Brown Oct. 18, 2013
    I was also very surprised by my results. My transportation wasn't extremely high because i never fly in planes. However, I do travel a lot to go to soccer, hang out with friends and other activities. Soccer takes me far and Im forced to travel for long drives to get to one game. This uses up gas and energy. I would never be able to give up soccer though! Soccer is my passion and I am willing to drive for many miles for one game. Also, I try to carpool to as many possible games so we can save energy. Even though Im driving a lot, I feel better because I know that I am saving a little energy. I wouldn't be able to give up traveling for soccer but I can use different techniques in order to stay eco-friendly.

Sahar Y-USA, Oct. 17, 2013

Hi, I’m Sahar and I’m from the US. I had a relatively high carbon footprint compared to what I thought it would be because I do average little things to refrain from wasting energy or water such as turning off the lights when I’m not in the room and turning off the water in the sink whenever it’s not in use. However, once I put in all the information to find out my carbon footprint data, it made a little more sense as to why my carbon footprint was high. I do travel abroad on a yearly basis to see family as well as driving everywhere I have to go as opposed to walking. In my home we also usually either have the air conditioning on or the heater along with eating meat on a regular basis. I am prepared to do a few things to lessen my CO2 emissions such as walking more often and limiting my consumption of meat to a few times every month. But, there are some things I’m not willing to change like my amount of travel or using the heater because my home is usually very cold without it on during the fall, winter, and early spring.

    Hi Sahar, I also had a high carbon footprint. It surprised me as well, and I definitely didn't think it would be that high. My total for home energy was 6557, and I was very confused because usually we use fans for air conditioning in the summer, and just bundle up in the winter. Then I realized it was because the heat was on all night in the winter, and the air conditioning all night in the summer. Not to mention all of our long, long showers. I too thought that I was doing little things to reduce my carbon footprint, but I realize now that I need to do bigger things if I really want to make a change. I, unlike you, do not travel on a yearly basis, but i understand why that would have such an impact on your carbon footprint and also why you would not want to change it. Good post!

Sidonie O - USA, Oct. 17, 2013

Hello everyone! I personally love to reuse and repurpose things that I might not otherwise use. It is always a lot of fun for me to make something new out of something old! There are many cute crafts that people can do to make useful or fun things out of their junk. One thing that I found recently was a basket made out of old newspapers. (Here is a link to a how-to video! http://www.youtube.com/watch?v=YsBEv-sdEm0) I have also found that some people make quirky home decorations out of tin cans (here’s another how-to guide! http://spoonful.com/crafts/can-do-robots)
On a more serious note, I have found that there are many ways to extend the life on electronic items such as phones and computers. One tip that I have found works extremely well to prolong the battery life of electronics is that when an electronic is brand-new, let the battery run out 100%— just let it die. Then charge it up all the way and try not to let the battery run out all the way again! Usually this prolongs the lives of batteries, at least in my experience, as well as the experience of many of my peers that have tried this. I think it’s important to prolong the lives of our technology as much as we can because at this point, people usually do not take the time to properly recycle it when it does die.

    That's pretty cool. I wish I was that creative. I always feel so wasteful because I constantly throw things away that can be reused. I'm not very or artistic but those sound like great ideas! My goal is to try and become more efficient and reuse more things.

    The battery thing is really interesting. I wonder why that is. It's a great way to conserve energy and use less carbon. It's fascinating how these little things make such a huge impact on our environment.
  • Isabella d-US Isabella d-US Oct. 18, 2013
    That's really great, prolonging battery life is a great way to keep carbon down as well as being generally helpful. I wish I'd known this sooner. Keeping your electronics nice and usable longer helps decrease the amount of carbon needed to produce those electronics. Supply and demand, if we need less new electronics then we'll have less of the carbon emissions that come with that. You're also very right many people don't properly dispose of electronics the way that they should.
    I also love recycled crafts, they always look even cooler than new products and are more eco friendly too. My friend and I all love to make things using recycled material. I'm planning on making a dress out of old candy wrappers just a soon as I can find the room. Recycled crafts are great, they're good for the environment, help keep down costs, and are much more creative than store bought goods.
  • Evan Lachman Evan Lachman Oct. 20, 2013
    I think that what you do is awesome! I think that it is very important to use an object as much as possible before disposing of it because it will just become another problem for our ecosystem. I myself do the same thing. Nowadays, many people are so impatient and need to upgrade the newest devise ASAP. I think that it is wasteful, selfish, and just stupid. I come from a family where we take the best care of things we can. All of us keep our cellphone for minimum two years. My father has had two phones in the last six years and they still run.

    I think the best way to keep items for as long as possible it to protect them. The amount of shattered iphones I have seen is mind boggling. That is a big reason the amount of time people keep technology for such a short time. I think everyone who owns and iphone should own a case. The crazy thing is that in todays world, we can get a very protective phone case for as little as $5. Also, once the time does come around that a new phone is needed, there are many places to properly recycle electronics.

After taking the Carbon Footprint challenge I learned that I use up way more carbon than the average person. When I realized this I looked back to see what I did that caused me to use up so much carbon. It showed me that the amount of showers I take and how long they are filled up a big chunk of my bar of carbon (oops!). I didn’t realize that just taking showers could really effect how much carbon I use. Recently, I’ve started taking quicker showers to fix that. Also, I’ve convinced my family and friends to recycle water bottles, paper, etc. more often. The Carbon Footprint Challenge was and interesting and fun experience for me, I learned a lot about what effects how much Carbon I use.

    I learned a lot from the carbon footprint challenge too! I had a similar experience with the shower problem. This is because I shower after every time I play basketball. Which is constantly! This also raised my food category because it made me really hungry. It was really hard to lower that. I had to start planting stuff in my backyard. Now you can call me a farmer.
  • Martin L-US Martin L-US Oct. 17, 2013
    Me too, I was shocked by the result, I never thought I would use that much carbon only by taking few flights , wow, I need to be careful about it now!

Discussions Discussion Deforestation SOS
Earl A-USA, Oct. 17, 2013

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.

Yes, it is a very good idea to think twice before throwing things away. If you have old clothes that you were just going to throw out, think again! Give it the charity, it does not only help them, but it gives YOU a good feeling too. Also, you could compose leftover food, that is a great way to help the environment. That gives you fertilizer which reduces the amount of plastic being produced for the bags of fertilizer you would buy at a store. You may not think you’re making a big impact, but oh trust me, every little thing counts! You could even make things out of the things you may be throwing away! There are many tutorials on pinterest, or youtube fun, easy, and useful things you can make out of objects you were going to throw away! So next time, think before you throw.

    I never thought about how composing leftover food to make fertilizer is not only good for the obvious, but also because of the packaging. Packaging seems to be a common factor we often forget or don't put into account.

Waste is a huge problem around the world, and even though recycling is an option, not everything is recyclable. What we really need to do is think twice before throwing something away. Ask yourself several questions such as:
Can I use this again?
Could someone in a worse situation than me use this?
Is there a better way to dispose of this than throwing it in a landfill?
Can I re-purpose this?
These are necessary questions because they would save a lot of waste. For example, with excess food, some of it can be composted. Old clothes can be donated to charity. Containers can be recycled.

    I agree, I think the biggest problem that the world has right now is waste. Especially bottles. Bottles are the biggest problem because they float in the oceans killing the sea life, and they are almost non biodegradable. There are plenty of things that someone can do with a water bottle, such as refilling it and using it again, or re purposing it for a craft or something that you can use around the house.
    I saw a post where someone had cut a water bottle in half, hung them from the window and used them as a planter to grow some tomatoes. If we were all to reuse and re purpose it we would drastically decrease the amount of waste and our impact on the environment.

    This is so true! i rarely think those questions. Im the kind of person who just throws stuff away! One thing i do, do is say im cutting an over sized shirt or making jeans into shorts i always save those pieces, they become very handy for other projects.
  • Cheng-Shi Yi Cheng-Shi Yi Oct. 21, 2013
    I think that we should start cutting down the use plastics, and recycle them properly, because the plastics float away out to sea and end up in seabird stomachs we end up killing them damaging the ecosystem.

hi, my carbon footprint was very high which was a surprise and not. I need to travel to visit family a lot. I generally turn off lightbulbs, although we don’t have many incandescent bulbs. I drive in a relatively fuel efficient car. I can not carpool because of my schedule. I do extra curriculars also.
I was surprised by how much food polluted. I didn’t know what a big difference a lightbulb could make also. What were you shocked or surpised about?

    I was really surprised how much I (and my family) pollute the nature with heating. I never even thought about how much energy we need to keep our house at 25°C. And I travel a lot to visit my family too, so my transportation section was quite high as well.
