On April 29, Americans across the country will unite to stand up for climate action at the People’s Climate Movement. Clean air. Clean water. A stable climate and a better world for generations to come. These are the things we will gather for. These are things all Americans want and deserve.

Wherever you live, there’s likely to be a sister march close by. While most people will join together in Washington DC for the national march, you can join or host one in your local community as well.

Are you ready to march? If you’re still not sure whether you want to fight back against climate disaster, here are 4 reasons we hope you’ll join the Movement on April 29:

1. For Right Now: Don’t be fooled. People are already seeing and suffering from the effects of climate change. Coastal cities across the world are plagued by floods and damage from rising sea levels. Entire communities are stricken with drought, and resources—especially some crop production—have been left vulnerable. And as we continue to spill dangerous pollutants into our air, we not only drive climate change, we also inflict major health problems on our most vulnerable populations.

2. For The Future: Things will get worse. If we stay on our current path, we’re tempting global disaster. Entire ecosystems would be damaged, species would go extinct, and people everywhere would suffer. Future generations would know a world that is less secure and more dangerous than it is now: a world where conflicts are exacerbated by more food and water shortages; where storms are stronger, temperatures are higher, and societies are forced to retreat from sinking coastlines.

3. For the trees… and the lakes… and the oceans… and the animals…: Humans obviously aren’t the only ones affected by climate change and pollution. As our climate becomes destabilized so too does the world we inhabit. Wildlife doesn’t fare so well when their habitat is totally disrupted. And the nature that we all love and need—those beautiful forests, gorgeous rivers, and grassy plains—will be greatly diminished.

4. For Everyone: There have been a lot of marches in 2017. From immigrant and refugee rights, to gender equality, people are fighting back for what they believe. The People’s Climate Movement joins that spirit—speaking up for everyone’s right to clean air and clean water and a healthy planet. There’s not a single person on this planet who will not be affected by climate change. When we march, we march together, and for everyone.

If you want to join the Movement, you can enter for a chance to win an all-expense paid trip to Washington DC to join Defend Our Future and other organizations at the march on April 29^th. Otherwise, check out this page to see where sister marches are popping up all across the country.
