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.

As the world’s population grows, we will need to produce more food to prevent hunger. The good news is that we have techniques that can both provide more food and lower the world’s carbon footprint. Scientists and farmers have developed farming techniques that would result in a “triple win”; more crops would be produced, they would be more resistant to drought and other extremes, and the crops would release less carbon dioxide into the air.
In order to help offset global warming, farmers have developed a way to grow crops that will not release much carbon dioxide. They do this by using fertilizers with a high amount of organic material. This traps carbon in the soil, thereby reducing carbon dioxide emissions.
The organic content of the soil also helps in making the crops more resistant to droughts and erosion. When more organic matter is introduced into a fertilizer, that fertilizer’s water carrying capacity increases. This gives the crops a store of water in case of drought, and it also helps to prevent erosion.
Scientists have also developed agricultural techniques that produce a higher yield of crops than before. Farmers can carefully monitor their soil’s fertility and nutrient levels and can adjust them as needed. Having nutritionally sound fertilizer can reduce the need to constantly replace it, and because the crops will be exposed to all the nutrients they need, more crops will grow.
As scientists have proven with the “triple win” technique, it is possible to produce large quantities of strong crops while still reducing our carbon footprint. If more countries implement this technique, we could take a huge step toward ending world hunger in an eco-friendly way.
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, 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.
HI, I’m William Lu now I’m studying at DIS. I’m going to talk about how to reduce air pollution. Air pollution come from the car, motorcycle, airplane, some ship, some factories, etc. And by reducing traveling by car or motorcycle we can reduce air pollution. If we want to travel from place to place we could walk, ride bicycle, ride bus, drive electrical car, drive electrical motorcycle, or subway. it can produce no or less air pollution. Stop buying too much thing would also help reducing producing air pollution, because it if you buying less thing it will let the factory to work less and the air pollution will be less too. When you use the air conditioner from the car too much you are using the gas more then without air conditioner. Planting trees can help filter out those polluted air,and plants will give off oxygen that we need. Travel less to other country will help reduce air pollution, because car, airplane, and ship will cause large number of air pollution.
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.
Hello everybody, my name is Vincent I live in Pessac (France). I think it’s very important to find a clean energy for the future. because soon the earth’s resourses will be exhausted. I consumed 5704 Kg of CO2 per years. I try to do somes actions for that. In my country the average is 9471 Kg per years. We should develop solar energy, wind energy. In my country there are not enought clean energy, so many people use a polluant energy, (fioul, gas). I think the neigbour will be equipped of wind energy or solar energy for some houses.
