Michael H-USA, Oct. 11, 2013

Hi, my name is Michael and I am a high school student in Oakland, California.

The biggest reason that is causing the climate crisis is the amount of waste going into the atmosphere. Most everyone has heard that these gases trap heat from the sun inside the earth’s atmosphere, changing the climate from regular to warmer.

One of the most obvious ways, according to me, to reduce this amount of waste in the atmosphere and return the climate to a more natural state, is to stop putting waste into the atmosphere and start taking the pollution already in it, out. One of the most effective ways to do this is to use the waste in the atmosphere as a fuel source rather than using new fuel, and some companies are doing just this.

This article, published back in March of this year, shows how one dairy company in particular is using natural gas from manure released by its cows as fuel for the surrounding community, its fleet of delivery trucks, and as fertilizer for its crops. This is not the only company to use this same method, but in one smooth stroke, it takes the methane (a greenhouse gas) released from its cows and converts it into electrical and diesel energy. While the company still burns this diesel to power its trucks, it is diesel fuel manufactured out of manure; recycled diesel fuel, and not new, from-the-ground diesel.

If we got every company in the world, from Coca Cola to Apple to BP, to recycle natural wastes into energy, like this dairy farm, and in turn use that energy, recycled energy, to power its processes, image the impact it would have on the environment. Such actions would effectively plateau the amount of greenhouse gases in the atmosphere, instead of adding to them and causing the greenhouse gas line graph to soar above previous points. Hypothetically, after we stop fretting over adding gases to the atmosphere, and recycle them instead, we could then specialize people to work on removal of gases rather than preach and solve their destruction.

Like many others have said here, eradicating the world’s poverty by 2015 is a stretch. Eradicating hunger is actually one of the greenest things on the list. To do that the hungry need to be taught how to grow/raise their own food. It is “locally grown” then. Universal education is harder to do without making the planet warmer. The school should ideally be run by solar power, but that is very expensive. Instead another green alternative would need to be found for that region. The school materials could be recycled. The students could be taught from a young age about (gender) equality. These are just my thoughts.

I think we’re on the road to changing the world into a better place and reducing poverty in many places but I don’t think we can worldwide eradication of poverty by 2015. On endpoverty2015.org they have a lot of useful information on this topic

Carbon dioxide is released when burning carbon-based fuels which include petrol and diesel in our cars, gas, oil, and coal in our homes, and jet fuels in planes. Too much CO2 released will lead to a climate change; therefore, it is important to find other sources of energy: wind energy, solar panels, and tidal power to name a few. How do these all work? Well, wind turns the propeller-like blades around on the rotor on the wind turbine which spins a generator to create electricity. Solar panels capture the light from the sun and convert it into energy that can be used by humans. Finally, tidal power is another energy source that uses the energy of the tides to create usable energy. Although it may be hard to use these alternates in some places, people should make an effort to use different sources of energy besides carbon-based fuels to reduce the amount of CO2 let off into the atmosphere.

While researching, I found that most countries source of energy was fossil fuel. 60% of most of the countries source of energy was fossil fuel. Naturally, we all know that burning fossil fuel increases greenhouse emissions. I found 2 alternative sources that are more likely, in my opinion, to succeed. The first would be solar power. The main reason for solar power would be that the sun is everywhere, and everyone could put solar panels on their roofs. The reason we don’t have it now is because it is expensive, but this should clear up in about a decade, as technology advances. The second would be ocean power. The main reason for this one is that the earth is over 70% water. The problem with this one is that it is also very expensive, and not nearly as developed as solar energy. It would take much longer than ten years before this could be used, but I think that it is definitely one of the better alternatives.

Hi everyone, my name is Andre, I am from Taiwan.
Clean,clean,clean! That’s what we need! I think it’s very important to have clean and safe energy. There are also different sustainable energy sources, like hydroelectricity, solar energy, wind energy, geothermal energy, and tidal power. I think we should use more sustainable energy, since it does not run out, unlike gasoline and coal. Shih men, a neighboring town near my house, are famous for its strong wind. So they have many windmills. Hydroelectricity is also a good example of clean energy. The Ming tan dam near the famous Sun Moon Lake makes 56% of Taiwan’s hydroelectricity. It is also a well-known tourism site. These are both examples of sustainable energy, but we need to use more of these renewable energy sources! We should focus on the energy sources that are clean and will never run out.

    Hello Andre! I think that your post is really interesting. The way that hydroelectricity plays a part in your country's energy production is extremely fascinating, as well as the resourcefulness when it comes to the strong winds and the implementation of windmills. You mentioned many sustainable energies, but one you didn't mention was geothermal energy. According to http://energy.gov/articles/ceres-making-biofuels-bigger-and-better geothermal energy is the energy that is produced by the heat of the earth. This energy can be produced from hot waters, hot rock or even molten lava underneath the earth's crust. Companies can install geothermal heat pump system into the ground and used the extracted heat and high temperature to produce clean energy. Also, the water extracted from the vapors can be used as a hot water source. Though this may be a difficult process, it can create a constant source of renewable, sustainable energy that can essentially be produced anywhere the earth produces a substantial amount of heat.

    Hello Andre, it is certainly critical that we begin to use various forms of clean energy around the world. It is good to hear that Taiwan has made such large steps towards this goal, as it shows that nations around the world are trying to produce clean energy. The Ming Tan Dam sounds very similar to the Hoover Dam in the United states, which is also a popular tourist site. It produces enough energy for 1.4 million Americans living around it, and is one of our biggest hydroelectric buildings. Hopefully we can move towards more solutions like this, such as wind and solar power, to give electricity to the majority of the people in our countries. It is good that we are moving in the right direction, but it is going to take some time for us to become entirely independent of fossil fuels. One or two countries will not be enough to make a significant impact, but if enough countries put measures in place like Taiwan and the US, hopefully we will be able to properly stop climate change worldwide.

Hello, I’m Julie from Texas, and I go to St. Agnes Academy. I believe that in order to make the earth greener, everyone must contribute. One person can do absolutely everything that they possibly can, but what they do will never really help the world as much as they hope to. What is needed is everyone to do even just a little bit of recycling or caring for the earth, it would be a much cleaner and greener place.

Hey everyone.

I think the best way to confront climate crisis in a way that positively impacts the majority of the other world issues we are faced with as a human race is to create a ton of eco-friendly jobs. Job opportunities give people a chance to earn money as well as help the environmental by either running a recycling program, installing solar panels, or building windmills.

    I couldn't agree more. If we were to give jobless people jobs with saving the environment, it would be like knocking out two birds with one stone
