However, environmental groups oppose Arctic offshore drilling, saying it will pollute and damage a natural wilderness largely untouched by human activity. They also argue that fossil fuels such as oil and gas must be left in the ground if the world is to avoid dangerous climate change.Over the summer, protesters in kayaks unsuccessfully tried to block Arctic-bound Shell vessels in Seattle and Portland, Oregon. "Big oil has sustained an unmitigated defeat," said Greenpeace UK executive director John Sauven."The Save the Arctic movement has exacted a huge reputational price from Shell for its Arctic drilling programme, and as the company went another year without striking oil, that price finally became too high."Shell had continued to explore for oil despite the slump in the price of oil. Other oil and gas majors have shelved expensive exploration projects but, having invested billions of dollars in its Arctic project, Shell persisted, believing that Arctic oil would be competitive in the longer term.This is why the announcement came as such a surprise.
Not mentioned in the article, but environmental groups recently announced that they would begin a consumer boycott of Shell fuels because of its Artic drilling.
