____What is micro plastic ?
Plastic is the most prevalent type of marine debris found in our ocean and Great Lakes. Plastic debris can come in all shapes and sizes, but those that are less than five millimeters in length (or about the size of a sesame seed) are called “microplastics.”
As an emerging field of study, not a lot is known about microplastics and their impacts yet. The NOAA Marine Debris Program is leading efforts within NOAA to research this topic. Standardized field methods for collecting sediment, sand, and surface-water microplastic samples have been developed and continue to undergo testing. Eventually, field and laboratory protocols will allow for global comparisons of the amount of microplastics released into the environment, which is the first step in determining the final distribution, impacts, and fate of this debris.

___A brief history of how plastic straws took over the world
In just the U.S. alone, one estimate suggests 500 million straws are used every single day. One study published earlier this year estimated as many as 8.3 billion plastic straws pollute the world's beaches.

Eight million tons of plastic flow into the ocean every year, and straws comprise just 0.025 percent of that.
But that hasn't stopped the straw from becoming the major focus of recent environmental campaigns. This is in part because, for most able-bodied people, the straw is something you can easily do without. Eliminating plastic straw usage rarely requires a drastic change in behavior.

Microplastics come from a variety of sources, including from larger plastic debris that degrades into smaller and smaller pieces. In addition, microbeads, a type of microplastic, are very tiny pieces of manufactured polyethylene plastic that are added as exfoliants to health and beauty products, such as some cleansers and toothpastes. These tiny particles easily pass through water filtration systems and end up in the ocean and Great Lakes, posing a potential threat to aquatic life.
Jellyfish and sea jellies are the informal common names given to the medusa-phase of certain gelatinous members of the subphylum Medusozoa, a major part of the phylum Cnidaria.
The octopus is a soft-bodied, eight-limbed mollusc of the order Octopoda. Around 300 species are recognised, and the order is grouped within the class Cephalopoda with squids, cuttlefish, and nautiloids.
Turtles are reptiles of the order Chelonia or Testudines. They are characterized by a special bony or cartilaginous shell developed from their ribs that acts as a shield.
Whales are a widely distributed and diverse group of fully aquatic placental marine mammals.
Clownfish or anemonefish are fishes from the subfamily Amphiprioninae in the family Pomacentridae. Thirty species are recognized: one in the genus Premnas, while the remaining are in the genus Amphiprion.
