Ecosystem Destruction

A variety of threatened or endangered organisms use the beach as a vital part of their life cycle. The nearshore ecosystem extends from the meiofauna that exist between sand grains to the carnivorous fish that roam the surf zone.

Components include birds that feed and nest on the beach such as the piping plover (US east coast) and various turtles that lay their eggs here. The first steps in protecting birds, turtle nests and the rest of this ecosystem must be the protection of a natural, un-engineered beach.

Another major threat to beach ecosystems around the world is the ever increasing human population in coastal areas. The global migration of people towards the coast causes competition between humans and other species and humans usually negatively impact other species. New construction in coastal communities destroys beach ecosystems with every parking lot paved, road expanded, or sand dune lost. This increase also puts a burden on sanitation systems, transportation networks, and increases pollution in these diverse ecosystems.

Mathematics predicts a sixth mass extinction

MIT scientists have analyzed significant changes in the carbon cycle over the last 540 million years, including the five mass extinction events. They have identified ‘thresholds of catastrophe’ in the carbon cycle that, if exceeded, would lead to an unstable environment, and ultimately, mass extinction.

Biodiversity just as powerful as climate change for healthy ecosystems

Biodiversity is proving to be one of humanity’s best defenses against extreme weather. In past experiments, diversity has fostered healthier, more productive ecosystems, like shoreline vegetation that guards against hurricanes.

A variety of maritime activities contribute to sea turtle deaths

Ask what water-based activity interacts the most with threatened and endangered sea turtles and many will reply without hesitation: commercial fishing. But state records show that to be incorrect.

Whales turn tail at ocean mining noise

A new international study has measured the effect of loud sounds on migrating humpback whales as concern grows as oceans become noisier. Scientists have said one of the main sources of ocean noise was oil and gas exploration, due to geologists firing off loud acoustic air guns to probe the structure of the ocean floor in search of fossil fuels.

“Dead zone” in the Gulf of Mexico is biggest ever

Each summer, a large part of the Gulf of Mexico “dies”. This year, the Gulf’s “dead zone” is the largest on record, stretching from the mouth of the Mississippi, along the coast of Louisiana to waters off Texas, hundreds of miles away. Around 8,776 square miles of ocean, an area the size of New Jersey or Wales, is almost lifeless.
