Thoughts on homelessness?

Our field revamps a lot of urban spaces and overgrown areas that people experiencing homelessness tend to use for shelter away from the public eye. What do you think our role is as landscape architects when it comes to addressing the homelessness crisis?

Edit: Not trying to solve homelessness, but I do think we can do more in our field to better our communities. Thank you to those who shared ideas. If we can design for ADA accessibilities, I believe we can add elements of design that give dignity to more vulnerable populations. Again, not implying we solve the homelessness crisis, just things to consider...
