Oceans of pollution - Features. A drumbeat of recent scientific studies emphasises an increasingly alarming convergence of crises for Earth's oceans.
The amount of plastic floating in the Pacific Gyre - a massive swirling vortex of rubbish - has increased 100-fold in the past four decades, phytoplankton counts are dropping, over-fishing is causing dramatic decreases in fish populations, decreasing ocean salinity is intensifying weather extremes, and warming oceans are speeding up Antarctic melting. One warning of humanity's increasingly deleterious impact on the oceans came from prominent marine biologist Jeremy Jackson of the Scripps Institute of Oceanography.
In a 2008 article published in Proceedings of the National Academy of Sciences, Jackson warned that, without profound and prompt changes in human behaviour, we will cause a "mass extinction in the oceans with unknown ecological and evolutionary consequences". Plastic, plastic everywhere… The most obvious impact humans are having on the world's oceans is pollution.

Despite spending billions on transit, Portland, Oregon residents depend on automobiles for their transportation needs.
A study released earlier this month by the Cascade Policy Institute questioned whether pricey mass transit options in Portland, Oregon are really being used by the public. The city has been a leader in securing funding for various forms of passenger rail and trolley systems. The Obama administration, for example, pledged $745 million in federal gas tax dollars to pay for the construction of a $1.5 billion, 7.3 mile light rail project connecting Portland to Milwaukie.
