And as you're writing that statement, Canada, United States and Russia are fighting over the oil reserves in the Artic ocean. Also, some governments want to exploit shale gas even though they know it has a huge negative impact on the environment and on the health of the people who live near it.
Maybe but they're happening more frequently and it won't get any better. Because of the global warming, glaciers are melting and are increasing the level of water in seas and rivers. (Don't forget they're the largest reservoirs of freshwater...)
For those of you who do not believe in global warming or are simply sceptic, I encourage you to watch this video on youtube
. If, after watching the video, you still believe we are not responsible for the well-being of not only the humans, but all of the other plants and animals that were thriving before we started destructing their habitat, well that's just sad.
