Moving on from the molecular stuff, plastic also has more visible impacts on the earth. First, learn about landfills, and what role plastic plays in the waste stream. Once plastics are in landfills, they could be contributing to leachate: you can learn more about this hazardous substance here.
Talking of hazards, plastic in the ocean is one of the greatest hazards of all. National Geographic explains how plastic pollution contributes to the ‘Great Pacific Garbage Patch’, and the National Oceanic and Atmospheric Administration (NOAA) tells us what it really looks like (hint: it’s not exactly a giant trash heap in the sea). They also delve into the science of how big these patches really are. You can learn more about the five major gyres in the world where pollution accumulates, and here’s everything you need to know about microplastics: where they come from, why marine animals mistake them for food, and why they’re capable of harming birds and other sea life.
But there’s hope: plastics can be recycled, after all. Here, you can view the steps involved in recycling a plastic bottle, which turns it into material that can be reused to make a number of things—sometimes, even art! Look at the Natural Resources Defense Council for some useful solutions to the problem of plastic waste, and some tips for what you can do to slow the flow.
Finally, this TED speaker shares some ‘tough truths about plastic pollution’, and in this talk, you can meet the man who first discovered those ‘garbage patches’ in the sea. To end on a positive note, in this Ted Talk, the speaker tells us how we can recycle all kinds of plastics with the help of a special recycling plant.
