Modern artists create things, not just to please us, but to raise awareness about our world. For example, every day we may use plastic, mindlessly pass by a homeless person, or fail to ever visit libraries. But thanks to art, we can see things like these again and strive to do better.

We at Enlighten love meaningful art and would like to share some pieces with you that house deep, meaningful ideas inside.

1. This artist furnishes old manholes to bring awareness to homelessness.
