Global warming can have many negatives affects on the world one of the main things would be a rise in the sea levels because of ice rapidly melting, this could cause many places to flood, this is destroying known habitats for many animals like polar bears, etc. This could cause droughts in many places the more that temperatures rise, and this will result in huge losses of locally grown crops, it could causes villages to have to relocate because lakes have dried up, there may be less food for certain locations because the fish will die, bird could begin to die off, etc. Though there are many positives stated below about Greenland it comes with many negatives, Global warming can cause the ice to become so thin that the people of Greenland cannot use their sled dogs to hunt or even take regular routes to hunt sea lions, and seals. They also would not be able to feed their dogs or families if they cannot hunt. As well as affecting the lives and breeding processes of any animals that depend on sea ice for birth or their way of living.

Global warming can also have lots of positives like the article i read on the National Geographic about Greenland. The grass is growing much fast in Greenland which is helping the sheep farms and its productivity, they have also been able to locally grow potatoes, broccoli, and other vegetables. Fish are moving into the Greenland waters making it better for the local fisherman because the ice has melted, it is opening up opportunities for mining gold, and other metals from mineral-rich rocks as well as oiling companies being able to do work in some areas.
