The text is the original version of the speech given by actor and film producer Leonardo DiCaprio in 2014 at the obligatory climate conference at the United Nations.

In 2014, the UN Secretary-General elected Leonardo DiCaprio to be the UN's climate change peace ambassador, and he was allowed to give a serious speech on climate issues to world leaders.

Uddrag
DiCaprio´s intention with the speech is very clear. He has been specifically selected as an authority to address the major climate problems that are rife around the world.

This is the task of DiCaprio to stage and address the problem. Leonardo DiCaprio does not refer to himself as an expert, and he therefore uses the form of appeal logos.
