How do it get my ideas noticed?

I have hundreds of great ideas that could dramatically improve the world (such as a large design for a self sufficient tree house city for kids (with things like human powered lifts and vegetable gardens) that is actually insanely good and could keep more kids off the streets as well as teach them many life skills) but I’m a 12 year old girl in a small city with poor parents. How do I get these ideas know?
PS This is in Physiology because I didn’t know where else to put it.
The kids my age are not so bright and don’t care about the world plus I’m home schooled.

Do you know anyone in your family, like an Uncle or older Cousin who may have connections to help you with your ideas. Be careful who you tell your ideas to. Some people will steal them and make them their own. Good luck.
