Obama's green signal to drill Arctic Ocean

It is not understandable why President Obama has given a green signal to Shell to drill two oil exploratory wells in the Arctic Ocean this summer. Arctic Ocean in the northern hemisphere remains covered by ice for most of the year. It is one of the few places on our planet that is yet to be touched. Due to the rise in temperature and climate change, Arctic ice is melting at an increasing rate. At this critical juncture, drilling in Arctic Ocean is too risky. President Obama should review his decision and disallow Shell Oil from drilling wells in the Arctic Ocean for the greater interest of our planet and its people.
