Explain in your own words what was the most single most important fact about plastics and microplastics that you learned in the course of this project. 

The knowledge that I've learned that is the most important for me about plastic and microplastic is that microplastic takes millions or even more years to break down. I always think that microplastic is just like little plastic stuff and it might break down in about one century or five decades or more. I can't imagine how long it takes. 

Also microplastic size is super tiny. It's not any plastic stuff or some little plastic toys, the size of it. No. It is like if you take the cap of the plastic bottle and shove down with a small small little part of it and that is the size of microplastic. The size of it makes it so hard to find a spot in the whole ocean or in the whole land so I think I can understand why people always say no more microplastic and no more plastic.
The reason I think those knowledges are the most important ones is because they're the ones that impressed me the most and it's the one that is most counterintuitive.

Explain in your own words what was the most single most important fact about diversity that you learned in the course of this project.

 The most important fact about biodiversity is that it is separated into three kinds of biodiversity.

• Ecosystem diversity: The number of different habitats and ecosystems in a given area is he ecosystem diversity.

• Species diversity: Species diversity measures the number of different species found in a ecosystem.

• Genetic diversity: The variety of genes within a given population or species is known as genetic diversity, and it’s the bedrock of modern agriculture because farmer can change random plant into valuable crops.

 And most of them are in our school. It's very cool because you can only think of the ecosystem and the animals and the plants when you think about biodiversity. However there's actually a lot of it and their definition is very different. 

Furthermore, I think this genetic diversity is a most interesting one because it is very detailed. You can find out that there actually are a lot of genes in the given population species and it is very cool and is about race. People who learn about this must put in hard work memorizing which kind of animal has how many kinds of genes and the race of them.
