And every day we make the small decisions that contribute to this problem—especially when we use single-use, disposable plastic products. Well over half the plastic that now threatens to entangle, drown, choke, poison or starve marine life and seabirds comes from land. And one of the biggest sources is from single-use plastic bags.
