Things are different living on an island. Composting and recycling here is just the way of life. When you live here for a while it just becomes second nature. There is no "trash pick up" like on the mainland. You are responsible for taking your own garbage/trash to the waste station (dump).
And please don't call the mainland the "U.S."... this island is also the "U.S."!
Sustainability is what life here is also all about. Growing a small garden is commonplace, even if it is only for salad greens or herbs or pineapples, papaya, bananas or a citrus or two. In mango season it RAINS mangos on the roads!
