    Welcome. My name is {name}, and I’m an educator here at {institution}.

    {Cue Seattle Aquarium Solar Array (video)}

    Did you know that we/some aquariums have solar panels on our roof? {Start video}

    In this video you can watch the installation of Seattle Aquarium’s solar panels taking place over the course of several weeks. You can see in the center of the screen that amidst the bustle of the city the appearance of the/our roof is slowly changing as each panel is added to the array. The Seattle Aquarium took this action for our ocean’s health by participating in a community solar (renewable energy) program with their local energy company. {Pause until video ends}

    Wait a minute…what do solar panels have to do with the water beneath us? {Pause}

    Scientists have discovered that burning fossil fuels like coal, oil and natural gas causes a serious problem called Ocean Acidification (OA). Now that we know about this problem, as concerned citizens, we have a responsibility to be a part of the solution, for future generations and for the health of the ocean.

    {Cue CO2 Accumulation (video)}

    Some carbon dioxide, or CO2, is needed for life processes. We can call this regular CO2. But CO2 is not just something that plants breathe in and we breathe out. It’s also something that gets put into the atmosphere when we drive our cars or burn any kind of fossil fuel. And these things are putting a lot of CO2 into the atmosphere and ocean. We can call this rampant CO2 because there is too much of it and it’s getting out of control.

    {Start visualization} You can see this in the image on the screen behind me. The cloud forming around the Earth represents the increase in CO2 in our atmosphere.

    Of course, CO2 is actually invisible. This cloud is simply a way of visualizing what we otherwise would not be able to see.

    But, all of that CO2 doesn’t just stay in the air…

    {Cue Ocean Acidification (video)}

    {Start animation} Now we are looking at a video that shows how the ocean naturally absorbs much of that rampant CO2 like a giant sponge. As the ocean absorbs this excess CO2, it reacts with sea water, changing the ocean’s chemistry. This process is called ocean acidification.

    {Cue Species Impacted by Ocean Acidification images. Click 5x –(series of images)}

    Many marine species that live in the Pacific are being affected by ocean acidification now. Studies have shown that many species—the Olympia oyster, red sea urchins, northern abalone, and turban snails are all impacted by ocean acidification. What do all of these animals have in common? {Pause, solicit response from audience if possible} They all have a hard shell.

    Did you see any animals with shells today?

    What did you see?

    So, what does ocean acidification actually do to those animals?

  6. 06

    {Cue Pteropod Shell (images)}

    Let’s look at a microscope image of pteropods, a type of swimming snail, to see. This is what happens to shells when they are exposed to these conditions. You can see the shell of the pteropod exposed to ocean acidification on the right, and has visible damage, making it harder for the animal inside to survive.

  7. 07

    {Cue Ocean Food Web (video)}

    You can see here how shell–building animals, like pteropods, are connected to other species. If these animals struggle to survive it could cause shifts in the ocean food web. This may threaten the balance of the global food web system of which we are all a part. But, we don’t want to wait to see how bad it gets. We must take logical steps now to ensure that we will have a healthy ocean in the future. {Pause once animation stops}

    As we have already seen, humans are amazing innovators. We created an energy system that improved our lives but which we now know is causing major problems in our ocean. The key to getting our ocean back to functioning the way it should is to get away from using fossil fuels for energy.

    What actions really make a difference?

  8. 08

    {Cue Renewable Energy Solutions (image)}

    Fortunately we innovative humans have already created other energy systems that do not rely on fossil fuels; systems such as solar, wind, wave, and geothermal energy. Our next challenge is to implement these renewable energy systems on a large scale, replacing our fossil fuel–based system with one that will provide us with the same power but without the negative impacts of rampant CO2.

  9. 09

    {Cue Seattle Aquarium Solar Array (video)}

    We need to change our actions not just at the individual level, but at the neighborhood, city, state, and national level. The more people who take action to tell our energy companies and governments that renewable energy is important to us, the more likely it is that we will see large scale shifts towards a system where renewable energy is the key rather than fossil fuels.

    We have created a system which provides us with great power, but with great power comes great responsibility—the responsibility to replace fossil fuels with more renewable energy sources to ensure a healthy ocean and a healthy planet for our future.

    And that is how the solar panels on our roof are connected to the water beneath us!
