The quality of water we use and drink determines in large part quality of our lifes. Clean water is essential to the health and well-being of people preserving the integrity of the natural environment and sustaining economies.

Water is refreshing, hydrating, and invaluable to your survival. But clean water remains a precious and often scarce commodity - there are nearly 800 million people who still don't have regular access to it. Why is that? And how can you tell whether the water you have access to - whether from a tap or otherwise - is drinkable?

Between Bienville's "Beautiful Crescent" and Lake Pontchartrain, lies Bayou St. John - the reason New Orleans is located where it is. WYES TRICENTENNIAL MOMENT on the "Old Portage" of Bayou St. John.

After years of hearing about the famous "garbage patches" in the ocean's gyres, the crew is stunned to learn that the patches are a myth: the waters stretching to the horizon are clear blue, with no islands of trash in sight. But as the crew sieves the water and sorts through their haul, a more disturbing reality sets in: a fog of microplastics permeates the world's oceans...

Known as "hotspots of biodiversity," seagrasses and mangroves attract and support a variety of marine life. However, worldwide damage and removal of these plants continue at a rapid pace. Changing Seas travels along Florida's coastline to get a better understanding of the significant roles mangroves and seagrasses play within the state.

Modern life would be impossible without plastic - but we have long since lost control over our invention. Why has plastic turned into a problem and what do we know about its dangers?... 51 Trillion particles of microplastics float in our oceans. Yet there is very little science of how this affects our health. This video shows why we should gain back control over plastic in our lives.

The Microplastics in the Baltic project is assessing the impact of plastic in biodiversity, climate change and human health in the Baltic region. IUCN is leading the first worldwide project to study the possible impacts of plastic in ice formation and melting. We will understand if plastic has any impact in sea ice formation, how much plastic is actually "scavenged" from the water and incorporated in ice and if plastic (at high concentrations) can play a role in ice melting.

The Mississippi River drains water from 31 different states, where rain and snowfall make their way south and make the river swell in Louisiana." This video investigates the Bonnet Carre Spillway, a flood control structure designed to prevent flooding from the Mississippi River

Private companies have invested tens of millions of dollars building "mitigation banks," critical marsh restoration projects to help save the fragile Louisiana coast. But the market for these banks might be too inhospitable.
