Similarly, an increasing proportion say that the rise in the earth’s temperature has mostly been caused by human activity. Currently, 42% say the warming is mostly caused by human activity, such as burning fossil fuels, while 19% say it is mostly caused by natural patterns in the earth’s environment. Last year, 38% mostly attributed global warming to human activity and in 2010 34% did so.
So we probably will need the “believers” in the European Union to step up pressure on the rest of the world, if we want concrete action to save our earth. And a few more court actions against polluters, as Robert Redford suggests.
