�������� Fellow Linda Amaral-Zettler and colleagues coined the term "Plastisphere" to describe the microbial communities living on marine microplastics.

The defining issue of our anthropocenic era is without doubt ecological in nature; to what extent is human action adversely affecting the natural world we inhabit? What can be done to reverse the accelerating contamination of our planet with synthetic materials? Global awareness about the catastrophic effects of greenhouse gases on the atmosphere and plastic waste on the environment has increased tenfold as governments  to implement worldwide climate action strategies to tackle the growing threat of an ecological catastrophe.  

One of the most serious threats is pollution caused by plastic waste. Our  of plastic-based products is suffocating our oceans, with plastics being ground down over decades into quasi-invisible micro-plastics that destroy wildlife, even having been found to have entered the . Around 8 million tons of plastic ends up in the oceans , maybe more, with 80% of all marine debris being plastic-based. It has been detected in the deepest of sea sediments and on the remotest of islands, as marine currents disperse the waste around the globe, contaminating precious habitats and threatening fragile ecosystems.
