Art reference for conservation

My love for animals is great, very great. So with selling my pictures i replace my photo equipment, but i hope when i am selling more, that i can donate a part of the income to conservation organisations across the world. To save orangutans, bigcats or educate people to conservate our planet!. How i will do that? First priority is to keep my camera and lenses up to date. And i hope in the future i can donate at least 25% of my income to those organisations who stand for the same ideas like i do.

Do you know a good organisation? Let me know and maybe i will add them to my list  of charity's
