        text: "<h2>Top Emitters</h2>China, USA, and India together emitted almost half of the total amount of emitted carbon dioxide in 2017 (Global Carbon Atlas 2017). Carbon dioxide is an important part of the atmosphere. It contributes to the greenhouse effect, which causes heat to stay on the planet. However, if the atmosphere has too much carbon dioxide, the planet will become warmer (NASA 2019). This causes glaciers and permafrost to melt, while corals and other ocean life dies because of the high amount of carbon dioxide in the water (Earth Vision Trust 2018). ",

        text: "<h2>Greenhouse Gases</h2>According to EPA (2019), a greenhouse gas is a gas that traps heat in the atmosphere (EPA 2019). It is crucial to have a balanced amount of greenhouse gases in the atmosphere, not too much, not too little. EPA describes that carbon dioxide is by far the most emitted greenhouse gas, making up 82% of the emitted greenhouse gases in 2017. Another common greenhouse gas is methane, being emitted by different industries and even animals.",

Earth’s climate is warming, meaning individual days can still have colder weather while the average day is warmer than a few years ago (NASA 2019).",

        text: "<h2>The Importance of Forests</h2><img src='resources/q5_img1.jpg' /><img src='resources/q5_img2.jpg' /><br />Forests are extremely important, trees absorb carbon dioxide and return oxygen. This is even more important now, since it can help with absorbing the excess carbon dioxide. However, forests are being cut down in great amounts, and the biggest driver is agriculture (Persson & Henders & Kastner 2014). Another devastating side-effect of deforestation is the loss of animal and plant life’s habitat, causing imbalance in the ecosystem (Pachamama n.d).",
