Join Kimberli Ponzio, an Environmental Scientist IV in the Bureau of Water Resources, as she discusses the benefits of wetlands and the work of the St. Johns River Water Management District to restore and protect wetlands.

First Nations reserves across Canada struggle to access clean drinking water from their taps. We explain why this problem has persisted and what the Trudeau government is doing about it

Like microbeads, polystyrene plastics are environmental hazards. They are extremely toxic to make and difficult to recycle. Polystyrene and "Styrofoam" are even banned from many recycling programs because of contamination problems - less than 2% of polystyrene was recycled in 2013.

Submerged aquatic vegetation (SAV) includes aquatic grasses (seagrasses) and attached macro-algae. SAV is highly valuable habitat since it provides numerous important ecological functions that are difficult to replace; yet it is especially vulnerable to coastal development and water quality degradation.

Where rivers meet the ocean, coastlines tend to bend either inward or outward, creating estuaries and deltas. But how do they get those shapes?

It is often easy to use empty metaphors or scientific jargon to explain the impacts and future related to coastal land loss. But when scientists take the time to elevate the voices of people that are losing their homes and livelihood, science and stories blend to have deeper impacts on those looking from the outside. In this talk, Madelyn Smith shares her photography, and the stories of people photographed, to illuminate the urgency and broader impacts of Louisiana's coastal land loss.

A proposal to build a hotel and conference center in Fontainebleau State Park near Mandeville has yet to receive a public vetting - that comes Wednesday night - but is already generating controversy among some north shore residents and environmentalists. Opponents have cited several concerns, ranging from the prospect of more development at the 2,800-acre park on the shores of Lake Pontchartrain and the lack of local input in planning to the specter that the proposed resort will eventually include a gambling casino.

Despite the valuable role that mangroves and seagrass play in the Florida Keys ecosystem, these plants are facing one particularly large threat: Us. In the Florida Keys, human development is the greatest threat to mangrove communities. Since the 1950s, more than 60 percent of mangroves in Monroe County have been destroyed for development. Activities such as dredging, using herbicides, and increasing waste water runoff have destroyed thousands of acres of mangrove habitat.

United Nations - Learn how the 2030 Agenda for Sustainable Development will transform the world, and why it is a priority for the United Nations.

Marine debris is all the manmade stuff that ends up in the oceans - from soda cans and plastic bottles to sunken ships. There's marine debris in every ocean on Earth, and all that junk can kill and injure sea life, impede navigation, leach chemicals, and even end up in our food.
