Earth Day’s 40th anniversary is today! How are you going to be celebrating?
Here at The Nature Conservancy, we’ve been thinking about ways we can help protect oceans – which contain some of Earth's most fragile and critical habitats. Help us celebrate Earth Day by following these three easy steps to help protect our oceans.

1. Use Reusable Bags
What you buy and who you buy it from can be a great way to make a statement about the environment. But it’s not just what you buy that can have an impact on the planet, it’s how you bring those items home.
Whether it’s organic fruit or a plastic toy, most of us end up schlepping things home in plastic bags – around 100 billion a year in the United States alone, according to the Worldwatch Institute.
These bags and other plastic debris are choking our waterways, killing hundreds of thousands of marine mammals, birds and sea turtles annually and swirling around in our oceans in large gyres.
But there is something you can do about it. Ditch the plastic and start carrying reusable shopping bags. If you were to replace just 10 plastic bags a week with a reusable bag, you’d be saving 520 bags a year!
That might still seem like small potatoes in the grand scheme of things, but imagine the numbers if everyone in your neighborhood gave up plastic bags. Or everyone in your town! Every little bit adds up.
Our online community has already been sharing tips on their favorite reusable bags, where to find them and, of course, how to remember to bring the darned things into the store in the first place.
2. Choose Sustainable Seafood
Oceans provide the primary source of protein for more than 1 billion people around the world. And for centuries, the ocean’s bounty seemed inexhaustible. But humans have altered our oceans' ability to provide for us.
While the Conservancy is tackling that problem by working with communities to restore degraded habitats and rebuild depleted fisheries, it’s important that people remember to choose sustainable seafood.
The Monterey Bay Aquarium seafood guide is the go-to source for making the most responsible seafood choices. They even have a pocket guide to ensure that the information is always at your fingertips. Forgot your guide? Just text Blue Ocean’s FishPhone to help you choose sustainable seafood at the grocery store or in a restaurant.
More and more chefs are also realizing that sourcing sustainable seafood for their restaurants is an important step in ocean conservation.
“By value, around 70 percent of the seafood eaten in North America is ordered in restaurants, which means chefs in particular have a need to source seafood responsibly,” says Dan Barber, executive chef/co-owner of Blue Hill and Blue Hill at Stone Barns. “That means considering not just the appetites of our diners, but also the health of the oceans.”
Read more about why ocean conservation is so important to Barber and world-renowned chef Mario Batali (and be sure to check out their sustainable mackerel recipes).
3. Green Your Gardening
What could gardens and oceans have in common? A lot, it turns out.
Conservancy marine scientist Steph Wear has spent a lot of time in the water. After seeing firsthand what chemicals and toxic substances can do to coral reefs (like toxic algal blooms and overgrowth of seaweed on coral reefs), it’s no wonder she refuses to use chemicals on her suburban central Florida yard.
Wear explains how pesticides and other lawn chemicals end up in our waterways and provides tips on how to maintain a beautiful yard without harsh chemicals or pesticides. And what about your vegetable garden? Wear says that a square-foot garden can produce up to five times the produce that a traditional garden of the same size would yield, while using 90 percent less water and 95 percent fewer seeds (and of course, it’s chemical-free!).

Finally, in honor of Earth Day, you can treat yourself and do something special to protect coral reefs at the same time – adopt a coral reef or see Disneynature’s OCEANS between April 22 and April 28 (a portion of ticket sales will go to the Conservancy’s coral reef work in The Bahamas).
Happy Earth Day!
