6 technologies that protect animals from poachers

[Catherine]

These are great ideas. We have some amazing technology. Why not use it to save endangered species. Rhinos are the ones who need the help the most right now, but I am sure it can be applied to a lot of situations.

Aren't these great.
I love the 3D printer Rhino horns. They could flood the market and make Rhino horn so cheap and plentiful that it would not be worth the risk of poaching.

Would that work for ivory? I could save elephants. There are so many possibilities with these ideas.
