My experiments were testing the decomposition rates of different single use compostable straws, and seeing which compostable straw consumers would prefer, to distinguish the best alternative to plastic straws. Overall, I decided to create 3 criteria to determine the best single-use straw
1. Consumer preference
2. Manufacturer environmental impact
3. Decomposition
I researched, interviewed experts, and conducted 2 experiments to gather information about the 3 best single use straw alternatives. The reason I chose this topic is that I care about the environment and plastic kills more than 1 million sea creatures a year, and that number is only increasing. In the US alone, 500 million plastic straws are used daily - enough to wrap around the circumference of the earth 2.5 times a day. Not only are the sea creatures affected, but the whole ecosystem. Eventually, the plastic breaks down, and turns toxic. When we eat seafood, the toxins from the fish enter our body, making us very sick.

One of the reasons plastic straws are so harmful, is that they are made out of a plastic called Polypropylene. This plastic is difficult to recycle and it usually ends up in our oceans. Also, this plastic is made out of petroleum, which can turn our drinks toxic. If it doesn't end up in our oceans, than it will still take over 200 years to decompose.
