environmentally conscious, as they have been made aware of their harm they have caused, making it worse for business. If humans keep industrializing, it is practically suicide. An Energetic Onion Skin – same question for the atmosphere. How is global warming affecting our atmosphere, and what problems is that causing Humanity? The ozone layer is being depleted. This is opening up holes in which UV rays are more potent. Sunlight passes through the atmosphere and warms the Earth’s surface. This heat is radiated back toward space. What is happening now is that most of the outgoing heat is absorbed by greenhouse gas molecules and re-emitted in all directions, warming the surface of the Earth and lower atmosphere. It is causing more concentrated heat, which is leading to droughts and famines in which humans cannot survive. It is killing off humans in areas that are heavily affected. Playing at Canute – what is the big unknown about ocean warming and the polar ice caps? I think the big unknown is how to stop the heat transfer. But what can be done to regenerate the ice caps? There are negative temperature decreases, which has been a positive 3
Martin sign that some areas are living. It is inevitable that, given out current rate, the ice caps will continue to melt. The unknown comes from when the oceans will rise and expand and by how much. The ocean waters will continue to warm, so it is the fate of the polar ice caps that will most determine how much coastlines change in the coming decades. Essay: The Earth is a huge ecosystem. Everything has a role and is vital to how well it runs. Humans play a big role in how the ecosystem is regulated because as population increases, the carbon dioxide output has also increased. As population increases, so does the need for more housing and buildings. This
