Sea swimming increases ailments


This picture taken in Salinas del Rey beach (Caribbean coast of Colombia) is a good example of how litter can be harmful to the environment in several ways.
A medical waste bag containing blood is a biohazard item that should not be found along any seashore due to its inherent nature and potentiality to spread infectious bloodborne pathogens.
Furthermore, this dangerous litter can also act as an enabler of biodiversity loss in our marine environment by allowing the invasion of local waters by non-indigenous species. Alien species such as bryozoan and polychaeta colonies, often use plastic litter in the ocean as a habitat on which to settle or as raft material for migrating into new territories, ultimately posing a threat to the integrity and functioning of ecosystems.

Large-scale commercial fishing covers more than half of the oceans, study finds

The EU has banned discarding caught fish in February 2013. The ban has been phased in gradually, beginning with the North Sea in 2014. By 2019 it will cover all the EU’s fisheries, with some exceptions. Regulatory tools such a seasonal or area closures can help but, alas, cannot completely eliminate the discard problem. Once a fish is caught, it is almost certainly going to die either because it is out of the water or because it was injured in the process… Captions: OECD Observer

In Defense of Biodiversity: Why Protecting Species from Extinction Matters


Photo source: ©© Drriss & Marrionn

Excerpts;

A number of biologists have recently made the argument that extinction is part of evolution and that saving species need not be a conservation priority. But this revisionist thinking shows a lack of understanding of evolution and an ignorance of the natural world.

Here’s the point: All life today represents non-extinctions; each species, every living individual, is part of a lineage that has not gone extinct in a billion years…

10 threatened U.S. coastlines

Old wells, new problems: Once upon a time, Summerland, California, was the offshore oil drilling capital of the county. And while the wells were abandoned nearly a century ago, many Summerland residents feel that the unprecedented amounts of oil washing up on their beaches in recent months may be the result of these old petroleum-harvesting spots.

Excerpts;

America’s 95,000 miles of coastlines are among the most scenic on the planet, from sandy white beaches to lush marshes to rocky cliffs. And yet, our coasts remain threatened. Coastal habitats can be destroyed by development, overfishing, pollution and even the dredging of sea canals. A proposal from the Trump administration would open up almost all of the country’s water territories to offshore drilling…
