How-To Create Transient Activist Art

I prefer the term "activist art" because it is positive, versus "protest art" or "social protest." There is nothing wrong with a protest, I participate in plenty, but if you can give something a positive label I think it is more effective and optimistic.

Is there an artist movement for your cause? Check here to see. I enjoy the Deviant Art gallery for inspiration. Don't forget Google image searches. While attending protests and actively engaging people to change issues is effective, often more passive communication can invite people to stop and think without causing intense emotional reactance and defensiveness. And at the end of the day, it wipes off, washes away, or disappears into the recesses of your social media feed.

In an effort to respect the environment, some forms of transient art are greener than others. It's also fun to invite children to participate in these activities. Here are some ideas:

• Chalk grafffiti
• Sand sculpture/writing
• Rock painting
• Snow art (use spray bottles of food coloring to write/paint on walls of snow)
• Draw with crayons on paper tablecloths at restaurants
• Use your finger or a sponge to write/draw on dirty/foggy vehicles and windshields
• Body art such as henna or temporary tattoos
• Change your avatar
• Create photo memes
• Hold a bake sale showcasing beautiful vegan cupcakes with a message, etc. 

Avoid anything violent or destructive. Don't:

• Carve trees or remove copious foliage/bark
• Permanently deface property
• Perform graffiti without permission
• Remove wet rocks from rivers/lakes for sculptures (there are tiny creatures that live on/under these)
