an oversion to spelling

As a member of The Wilderness Society, I'm treated to monthly letters urging me on to greater heights of activisim and generosity. The language is as florid as a Chinese translation and has such gems as this to keep members amused:

"... the United Nations identified the two primary drivers of species extinction as habitat destruction and human-induced climate change, and said that immediate action must be taken to overt the crisis."

It could be a simple plea to 'out' the two-pronged approach to extinction, but I somehow doubt it...
