A necklace that fights homelessness and 30 other holiday gifts with a bigger purpose.

At Upworthy, we believe a little generosity can go a long way. And that's especially true during the holidays.

So naturally, we wanted our 2016 gift guide to be tailored just for you — our big-hearted readers who can appreciate a great gift that also makes the world a better place.

We rounded up the hippest, neatest, most unique products we could find that give back to a variety of worthy causes in important ways. From empowering women in the developing world and keeping our planet pristine, to helping pets in need and fighting human trafficking, you and your loved ones can feel great about their presents this year knowing your purchase went to a cause near and dear to their heart.

Here are 31 holiday gifts that give back, separated into three sections — gifts for grown-ups, for kids, and for your four-legged friends.
