Also NASA's Aura satellite can identified a sulfur dioxide (SO2) trail to the south of the volcano. This can be very dangerous to the people living near there. With an eruption of this size the ash plumes and sulfur released into the environment can cause many problems for the environment in those areas. 17twomeyj https://padlet.com/17twomeyj/d2sunfq4h6vj/wish/163720153

Having 5 million dairy cows leads to major amounts of pollution in the rivers and fresh water sources. He also believes that the War on Drugs is not working and would be a good source of revenue to the farmers as opposed to dairy cows. He says that growing Marijuana would have a smaller impact on the environment and would also add revenue through taxes to the government. 17twomeyj https://padlet.com/17twomeyj/d2sunfq4h6vj/wish/163849169 http://www.livescience.com/58469-richard-branson-tells-dairy-farmers-to-grow-weed.html]]> 2017-03-30 23:38:49 UTC https://padlet.com/17twomeyj/d2sunfq4h6vj/wish/163849169 Permafrost Defrost As global warming continues to take hold on the earth many places where the ground used to be frozen permafrost is starting to thaw this article explains all things that happen as the ground defrosts and releases the gases and other things that where trapped in the ice.  this is a problem because this process releases a lot of greenhouse gasses into the atmosphere and continues to contribute to the positive feedback loop of global warming.  This is a growing problem because it is a positive feed back loop and will only worsen as time progresses. 17twomeyj https://padlet.com/17twomeyj/d2sunfq4h6vj/wish/163849430

This algae is called Noctiluca scintillans, that flourishes in low oxygen water, is blooming along the beaches and is pushing out the base of the food chain that exists there now diatoms, which are microscopic algae. these new algae create light through a chemical process that could make red, blue, or green light. This is different from biofluorescents absorbing light and releasing a lower frequency. If these algae replace the other algae that are there the food web could crash and would destroy the whole ecosystem that is there. 17twomeyj https://padlet.com/17twomeyj/d2sunfq4h6vj/wish/163850414 http://www.livescience.com/58296-bioluminescent-algae-glows-blue-in-tasmania.html]]> 2017-03-30 23:54:01 UTC https://padlet.com/17twomeyj/d2sunfq4h6vj/wish/163850414 Wind Power in the Artic Scientist have started to think of ideas to slow the shrinking of the ice caps at the poles. This loss of ice is caused by global warming and is rising the level of the sea. The idea is to put wind powered pumps on the ice and have them pump up colder water from beneath the ice caps to the surface and have it freeze over so that even as it warms up there is more ice so the process will be slowed. This is a ridiculous idea to actually implement the scaling of it would be very difficult and to spread the turbines all over the ice caps would be very difficult and to maintain or repair them would be even more difficult. This just seems like it would be a project to start and quickly fail. 17twomeyj https://padlet.com/17twomeyj/d2sunfq4h6vj/wish/164079278 http://www.livescience.com/57968-pumps-could-freeze-arctic-sea-ice.html]]> 2017-04-01 01:15:37 UTC https://padlet.com/17twomeyj/d2sunfq4h6vj/wish/164079278
