Thoughtful Thursday: March 22nd is World Water Day

Blog-Header-ConservationExp

It’s that time of year again.  Everyone’s favorite holiday – World Water Day!  What? Never heard of the holiday that celebrates the one substance that is the basis for all life?  Think about it, when scientists are looking for proof of life on other planets, what is the one clue they hope to find?  Water.  The simple presence of water.  They know that if there is water, there may be a possibility for life.  No water, no life.

Here on Earth, almost three quarters of our planet’s surface is covered with water.  The volume of water in your own body is made up of almost that exact same percentage.  We all need water to survive.  And by “we all,” I mean microbes, insects, kittens, people, polar bears, trees, frogs, flowers, birds, turtles, forests, ecosystems, etc.  We are all intricately linked through water.  As much as we try to separate these groups in our minds, as much as we disassociate ourselves with parts of the rest of the world, it would do us good to remember that we all have one common need.

What do sharks and humans have in common? Their need for water. Clean water.

There is some great information now available that helps us visualize how truly dependent we are on water.  We can see how much water it takes to make a one pound of beef, one pint of greek yogurt, one cup of coffee.  It’s all very fascinating – mostly because it forces us to look at water in new ways.  We live in a world where “conserve water” or “save water” used to mean – stop letting the faucet run while you are brushing your teeth, or don’t water your lawn in the middle of the hot summer day.

This new view of water, puts a truer value on the resources required to produce the food we eat and makes us think about our daily choices in different ways.  For example, it takes three eggs to equal the amount of protein in one serving of beef, but the beef requires nine times the amount of water to produce.

If we are committed to being good stewards of this amazing water planet, we need to start with our own daily choices.  Figure out what is most important to you and then look for ways to make less of an impact!

Thoughtful Thursdays: World Water Day

World Water Day

Held annually on March 22, the United Nation’s World Water Day brings attention to the importance of freshwater and advocates for the sustainable management of freshwater. Globally, freshwater accessibility is critical for the survival of all living things, yet it is a significantly threatened resource.

Yes, the world is 70 percent water, a staggering amount. Of that water, however, 97.5 percent is salt water and just 2.5 percent is freshwater. The UN and like-minded institutions hope that World Water Day will help people recognize the importance of freshwater and the need to conserve this precious resource.

Like all living things, aquatic animals require plenty of water to survive. So, how does the Aquarium keep our animals happy and healthy and still manage to conserve freshwater?

If you’ve visited the Aquarium in recent years, chances are you’ve strolled through Harry and Jeanette Weinberg Waterfront Park (the greenery in front of our Pier). Did you know that underneath the plant life is a system of cisterns? A cistern is a waterproof receptacle for holding liquids. In 2012, we were able to collect an estimated 200,000 gallons of rain water that was then used to water the park. As a result, not a single drop of domestic water was used!

National Aquarium staff have also worked tirelessly to design and implement the most efficient filtration systems throughout many of our exhibits. These upgrades saved more than 430,000 gallons of water last year! Additionally, our new Blacktip Reef exhibit will have a state-of-the-art filtration system installed to further reduce our need for water, while still providing a healthy and thriving environment for our animals!

Want to do your part to conserve freshwater? Here are some easy ways to get started:

  • Knowing where your water comes from is the first step in better protecting it! The Nature Conservancy has a great interactive map that can help you find your local water source!
  • When washing dishes by hand, don’t let the water run while rinsing. Fill one sink with wash water and the other with rinse water.
  • Put food coloring in your toilet tank. If it seeps into the toilet bowl without flushing, you have a leak. Fixing it can save up to 1,000 gallons a month.
  • Shorten your shower by a minute or two and you’ll save up to 150 gallons per month.
  • Water your lawn and garden in the morning or evening when temperatures are cooler to minimize evaporation. Better yet, plant native plants in your yard. They require less water, fertilizer and time!

March 20, 2013: The Streams of Maryland

freshwater plays in the survival of all living things!

Held annually on March 22, the United Nation’s World Water Day brings attention to the importance of freshwater and advocates for the sustainable management of freshwater resources. Globally, freshwater accessibility is critical for the survival of all living things, yet it is a significantly threatened resource. In Maryland, our own freshwater streams and rivers need our help as they run to the largest estuary in the United States, the Chesapeake Bay.

Even if you don’t live on the water, the health of the Chesapeake Bay watershed, which encompasses more than 64,000 square miles to six states and the District of Columbia, affects each of us every day. More than 100,000 streams, creeks, and rivers weave through the Chesapeake’s vast watershed. In fact, according to the Maryland Department of Natural Resources, we all live within 15 minutes of a stream, making freshwater health not just a Maryland issue, but a backyard issue as well!

Healthy streams are organically balanced, with enough oxygen to support life. Decaying plants and animal waste provide a balanced amount of nutrients, and the water is not too acid or too alkaline. In these healthy streams, runoff is kept to a minimum, and chemicals from farms, factories, and residential areas do not make their way into the stream. Countless species rely on healthy freshwater ecosystems to thrive. Fish, snakes, turtles, frogs, invertebrates…DNR states that Maryland is home to more than 100 species of fish, 20 species of salamander, and 10 species of turtle, just to name a few stream-dwellers.

The diamondback terrapin is just one of the many species of reptiles that rely on Maryland waterways!

In a recent assessment by the Environmental Protection Agency (EPA), just 45 percent of sampled streams in the Chesapeake Bay watershed were rated fair, good, or excellent. As outlined in the EPA’s Strategy for Protecting and Restoring the Chesapeake Bay Watershed, the goal is to improve the health of the watershed so that 70 percent of sampled streams measure fair or better by 2025.

To help increase our understanding of stream health, DNR coordinates a team of volunteers who collect important stream quality data across the state. This program, called Stream Waders, is the volunteer component of the Maryland Biological Stream Survey. The use of these volunteers allows more streams to be sampled, giving a big-picture view of Maryland’s waterways. Volunteers participate in a one-day training session, then spend a couple days in March or April collecting aquatic invertebrate samples from stream beds.

The study of aquatic invertebrates, such as mayflies, caddisflies, and dragonflies, is instrumental in the analysis of streams. Because invertebrates vary in their sensitivity to pollutants, a healthy stream has both sensitive and tolerant invertebrate species while an unhealthy one would have only pollution-tolerant species. Ultimately, the Stream Waders data is used in DNR reports and is available for review on their website.

In our daily lives, each of us can take steps to help keep our community streams healthy. Take a walk along a nearby stream and properly dispose of trash you find along its banks. Limit pesticide use in your yard so that it doesn’t make its way into freshwater supplies. Many local organizations host stream cleanups or wetland restoration events, so volunteer your time. Even just one day a year can make a real difference to a stream in your community.

Take action to keep our streams today by joining our Conservation team at one of our upcoming cleanups
