"Researchers at UH Manoa's Hawaii Institute of Marine Biology (HIMB) have examined the genetic structure of a common, non-harvested sea star using a spatially explicit model to test whether the largest sewage discharge and urban runoff sources were affecting the genetic structure of this species.
They found that these large pollution sources are not only increasing genetic differentiation between populations (presumably by limiting the dispersal of larvae between them) but also decreasing the genetic diversity of populations closest to them."
"In short, human beings are directly affecting the ecological and evolutionary trajectory of a species that is relatively free of any direct human impacts."

Wow we Humans have really done something awful this time to this Planet (with our selfish and irresponsible polluting of this planet!!) Let us hope we can find a way to solve this serious problem we have created! I hope all of my readers practise recycling of garbage to as great an extent as you can.
