explanation[1]="About 97% of the Earth\'s water is found in its five oceans: Arctic, Pacific, Atlantic, Indian and Southern. Oceans contain salt water, but other sources of water contain fresh water - water without salt. These include glaciers, snow, the ground, rivers, lakes, the atmosphere and even plants and animals. Over the course of 100 years, an average water molecule spends 98 years in the ocean, 20 months as ice, 2 weeks in lakes and rivers and less than one week in the atmosphere!"
explanation[2]="Oceans are important for all of these reasons and so many more! Oceans provide seafood, including shrimp, tuna fish, salmon, lobster and shellfish like oysters and clams. The average American eats about 16 pounds of fish and shellfish per year and the United States as a whole consumes over 4 billion pounds of seafood each year. Another important ocean benefit is oxygen, which is essential for us to breathe. Over half of the world\'s oxygen supply comes from tiny ocean plants known as phytoplankton. Like trees, they go through photosynthesis -  they absorb sunlight and nutrients and release oxygen in return. Finally, the world\'s oceans are important to weather and climate (the average weather over time). They absorb and store vast amounts heat from the sun. The ocean receives most of its heat along the equator, where incoming energy from the sun is most powerful. The ocean stores this heat and distributes it around the planet through ocean currents and winds, helping to control climate. This heat energy also reacts with the atmosphere above the ocean surface, creating weather patterns, such as rain storms and hurricanes."
explanation[3]="Whale sharks are the biggest fish in the sea, but blue whales are the largest animal on Earth. They grow to an average of 70 to 90 feet in length, but some grow to be more than 100 feet. That\'s the length of about 3 or 4 school buses lined up in a row! The weight of these huge whales can be anywhere from 200,000 to 300,000 pounds, about the weight of 15 full grown male elephants combined! Even their hearts are huge - the size of a small car. Blue whales are hungry creatures, but survive by eating tiny shrimp-like animals called krill. They eat 2 to 4 tons of krill each day. Unfortunately, the blue whale has been heavily hunted by humans and is now considered an endangered species. There are only 15,000 individual blue whales left in all the world\'s oceans."
explanation[4]="Leatherback sea turtles often mistake plastic bags for jellyfish, one of their favorite foods. Plastic bags are a real danger to leatherback sea turtles that attempt to eat them. The bags may get caught in their throat, making them very sick and unable to swallow any other food. Leatherbacks can also became tangled in the plastic and drown.  When plastic bags and other trash items end up in the ocean, they become known as \"marine debris.\" Marine debris can stay put in the ocean for quite some time before it biodegrades, or decomposes: it takes a plastic bag 20 years, a Styrofoam cup 50 years and an aluminum can 200 years! Each of these items, and all other marine debris, have the potential to harm many animals."
explanation[5]="Each of these simple but important steps can help keep our oceans clean and healthy for plants, animals and humans to enjoy! No matter where you live, rainwater washes litter from the street into storm drains, where it can flow into your local river and eventually the ocean. You can help at home by recycling and throwing trash in the trash can.  You can even help organize a trash cleanup in your community. If you visit the beach, \"take only pictures and leave only bubbles.\" Be sure to prevent your trash from blowing away in the wind and place it in a trash can before you leave. If there are no trash cans in sight, collect your trash in a plastic bag and bring it home to throw away or recycle. Also, use biodegradable sunscreen if possible, or cover up with sun-protective clothing while swimming, since some sunscreen chemicals can harm corals and other coastal life. Finally, this September, join over 378,000 volunteers worldwide in cleaning up your local stream, river or beach during the International Coastal Cleanup.
