Dear Friends,
Every minute, a dump truck's worth of plastic enters the oceans, and an estimated 150 million metric tons of plastic are already in our oceans. While many of us are already likely taking steps to reduce plastic pollution by recycling and reducing single-use items, we need governments to step up and be accountable.

This is how it is in the womb: warm, quiet and peaceful. Taking them away from their mother and littermates is traumatic. Even when you see a happy, goofy otter playfully engaging with their new family, keep in mind that they are away from the only home they have ever known, in a completely new enviro…
