Diatoms are found abundantly in almost every aquatic environment: oceans, lakes and wetlands, too. Because the frustule is heavier than the water surrounding it, after a diatom dies, the glass skeletal remains slowly sink to the bottom of the ocean or lake and become part of the sediment.

As a society, we’re addicted to plastic, but the good news is that we can choose to reduce our use so we can have cleaner streets, healthier wildlife and less polluted rivers and oceans. 18 billion pounds of plastic waste ends up in the ocean each year. Less than 10% of all plastics in the U.S. get recycled.

Although the three 17-year cicada species occur across the eastern half of North America (from Kansas to the Atlantic Ocean) the different populations of the species don’t have the adults emerging in the same 17-year cycle. This year they keep calling it Brood X. What does that mean? To read more posts in the cicada series, visit.

With ocean temperatures over 90°F off the Florida coast, Carl strengthened from a Category-1 with 80-mph winds to a Category-5 with 160-mph winds, in only 36 hours. Sea-level rise caused by the warming ocean means that there is no beach at high tide at several Jersey and Delaware coast points.

For native plants, birds and wildlife that live in or near these streams, it is like drinking a big glass of ocean water when you’re thirsty. All this salt runoff also depletes oxygen in local waterways, inhibiting a fish’s ability to breathe in the water and encouraging algae blooms.

We’re drowning in plastic, with 18 billion pounds of it ending up in the ocean every year. And 3 trillion cigarette butts — their filters made of plastic — are carelessly tossed, while millions of rolls of plastic food wrap, typically used only once, are discarded by U.S. households annually.

The Amazon Rainforest is home to the longest river on Earth that originates high in the Andes mountains as glacial melt and then crosses the entire continent to drain into the Atlantic Ocean. This web of rivers has a known effect on some Amazonian birds and primates.

Plastic water bottles create an enormous amount of litter — 18 billion pounds of plastic waste ends up in the ocean each year with devastating results on wildlife. Wherever you live, there are sure to be many others who are keeping our rivers, streams, lakes and oceans healthy by cleaning up. Brian Yurasits/Unsplash.
