I am thoroughly positively impressed by these youths determined that human-caused global warming will be slowed, stopped, and reversed with or without the "powerful"

"... the global youth-led day of action on March 15 will consist of more than 500 events in over 50 countries, with at least 16 taking place throughout the United States. [Source]"

Here's the full text of their powerful letter:

We, the young, are deeply concerned about our future. Humanity is currently causing the sixth mass extinction of species and the global climate system is at the brink of a catastrophic crisis. Its devastating impacts are already felt by millions of people around the globe. Yet we are far from reaching the goals of the Paris agreement.

Young people make up more than half of the global population. Our generation grew up with the climate crisis and we will have to deal with it for the rest of our lives. Despite that fact, most of us are not included in the local and global decision-making process. We are the voiceless future of humanity.

We will no longer accept this injustice. We demand justice for all past, current, and future victims of the climate crisis, and so we are rising up. Thousands of us have taken to the streets in the past weeks all around the world. Now we will make our voices heard. On 15 March, we will protest on every continent.

We finally need to treat the climate crisis as a crisis. It is the biggest threat in human history and we will not accept the world's decision-makers' inaction that threatens our entire civilization. We will not accept a life in fear and devastation. We have the right to live our dreams and hopes. Climate change is already happening. People did die, are dying, and will die because of it, but we can and will stop this madness.

We, the young, have started to move. We are going to change the fate of humanity, whether you like it or not. United we will rise until we see climate justice. We demand the world's decision-makers take responsibility and solve this crisis.

You have failed us in the past. If you continue failing us in the future, we, the young people, will make change happen by ourselves. The youth of this world has started to move and we will not rest again.
