The built environment in general and property development in particular, have significant impacts on all aspects of sustainability, economic, social and environmental. The development process impacts on resource consumption, energy use, biodiversity, water consumption and water course patterns, waste production and the physical design and impact of urban spaces.

Plant invasions result in biodiversity losses and altered ecological functions, though quantifying loss of multiple ecosystem functions presents a research challenge. Plant phylogenetic diversity correlates with a range of ecosystem functions and can be used as a proxy for ecosystem multifunctionality. Laurentian Great Lakes coastal wetlands are ideal systems for testing invasive species management effects because they support diverse biological communities, provide numerous ecosystem services, and are increasingly dominated by invasive macrophytes.

Ferreira's project used a novel, but effective methodology for removing ocean plastics. He used magnets to attract microplastics from water. The project found that a magnetic liquid called ferrofluid attracted the tiny plastic particles and removed them from the water. After nearly a thousand tests, his device successfully removed about 88 percent of the microplastics from water samples, according to The Irish Times.

St. Tammany Parish's supply of hotel rooms far outstrips the current demand, according to a study paid for by the parish's tourism commission, but even so, consultants say a 150-room hotel and conference center should be developed at Fontainebleau State Park near Mandeville. Not everyone agrees.

ISeeChange is a global community that posts about what they notice changing in the environment using our platform and mobile tools. Each post is synced with weather and climate data and broadcast to the community to investigate bigger picture climate trends. Over time, community members can track how climate is changing, season to season, year to year, and understand the impacts on daily life.

Natural disasters such as hurricanes, tropical storms, tsunamis, and landslides have the potential to generate a tremendous amount of marine debris. The high winds, heavy rains, storm surge, and flooding associated with these disasters can pull large structures, household articles, and outdoor items into surrounding waters.

Phosphates are chemicals containing the element phosphorous, and they affect water quality by causing excessive growth of algae. About 3 1/2 pounds of phosphates per person enter the environment in the United States annually from farms, yards, waste water and factory waste. Phosphates in water feed algae, which grow out of control in water ecosystems and create imbalances, which destroy other life forms and produce harmful toxins.

When oil is spilled into the ocean, it has some devastating effects on the ecosystem. How do we clean it up?

Oil spills are harmful to marine birds and mammals as well as fish and shellfish. Oil destroys the insulating ability of fur-bearing mammals, such as sea otters, and the water repellency of a bird's feathers, thus exposing these creatures to the harsh elements. Without the ability to repel water and insulate from the cold water, birds and mammals will die from hypothermia.

Below sea level. It's a universally known topographical factoid about the otherwise flat city of New Orleans, and one that got invoked ad nauseam during worldwide media coverage of Hurricane Katrina and its catastrophic aftermath in 2005. Locally, the phrase is intoned with a mix of civic rue and dark humor. It's also off by half. Depending on where exactly one frames the area measured, roughly 50 percent of greater New Orleans lies above sea level. That's the good news.
