These are some of the groups which are active in Hannover. But most of them are international, so in case you are living in another city, you can just search for them by using the name of the organization and adding your city in Facebook search. All these groups are always happy about new activists and it is a great way to get the message out there while connecting to new people. If there is no group, just start your own! Most organizations will be happy if you contact them and asking them about starting a local group in your hometown. You can also help out in shelters and sanctuaries, they are always happy about helping hands and there are many different ways to help out.

Vote!
You will never get everybody, no matter how many arguments you have and how right your message is. That is why politic is really important too. A real society shift will always be concluded by new laws. Like the laws of humanity which made all humans equal. Not long ago women were not allowed to work or vote for example. So always go and vote, even if the party is small and does not seem to have a chance right now, it is important that you vote them anyway. To keep them going and show your support. Believe in change! It happened before and will happen again. I always vote for the following party, which I am also a member of. They take a social approach, with high ethical standards, at most important to all topics. Compassion over money. For humans, animals and the environment.
