Ocean pollution

My senior year of high school I did a project on the great pacific garbage patch. This collection of garbage in the pacific ocean is as big as Texas. It is cause by this thing called an ocean gyre. The currents of the ocean flow in a way that keeps the trash in the center of the gyre. The trash is incredibly tough to pick up because the sun has disintegrated the plastic into small pieces. Over the past few years I have heard of a few ideas that were out there about how to pick up the garbage. There is still a garbage patch, no solution has been enacted. There are probably a number of smaller scale environmental issues that have been similarly put off. My question is why? What are we waiting for? The perfect solution isn't out there, inaction will not promote change. I write this questioning what is stopping change and how we can promote a culture of effecting positive change to the treatment of the environment, especially for Christians.
