You can't put a price on all mom has done for you -- but you can try to show your gratitude with one of these eco-friendly gifts. All are as good to Mother Earth as they will be to your own momma. From classic -- like recycled gold jewelry and Fair Trade chocolates -- to modern options (yoga gear, chic bags), we've got everything you need to make mom smile this Sunday, and forgive you next time you bring your laundry home.
