Leading scientists agree that the planet is in danger and that we&#8217;re approaching a point of no return. With the UN conference on climate change approaching in Copenhagen, the world needs strong commitments to emission reductions.\n\nBut while other countries are working toward solutions, your government is standing in their way. With the Alberta tar sands dictating Canada&#8217;s position in the UN climate talks, Canada is obstructing progress on a global scale.\n\nTar sands production already creates 40 million tonnes of CO2 emissions a year. And with production on the rise, so are emissions. In fact, because of the tar sands, Canada&#8217;s greenhouse gas emissions have grown more since 1990 than those of any other G8 nation. \n\nWe are asking that Canada be a part of the solution, not part of the problem. Please stop supporting tar sands expansion and start making real commitments to reducing emissions. True climate leadership and vision is needed now. Prime Minister Harper, we need an energy revolution. We hope that you will rise to this challenge or risk becoming obsolete while others move forward. The time is now. \n \nSigned,\n\nConcerned Global Citizen\n\n</textarea>\n      \n    </div>\n    \n      </fieldset>\n  \n  <div class=\"submit\">\n    <input name=\"commit\" type=\"submit\" value=\"Next...\" />\n  </div>\n</form>\n");
