Microplastics

Recently, I started to notice the issue (1) emergence of microplastics in the environment. Microplastics refers to is the small plastic particles which is (2) are smaller than 5mm across. Because the microplastics is are (3) so small, organisms (4) ingest eat them accidentally. The (5) Scientists had (6) have found microplastics in oyster and fish guts. Last week, I read (7) a piece of news claiming that the microplastics is even found in (8) human feces. (9) This is really awful ! I don't want plastics in my belly!
I tried not to use using plastics in everyday life, but it is was too difficult — When I go shopping in the supermarket, everything is was wrapped in plastics: no matter fish, meat, vegetable, even eggs and noodles....everything!
What can we do?

(Part Two)

Hi Fangling,

Thank you for sharing this. I think plastics is really a scary invention. 

Just some suggestions for your writing:

(1) We can use the word "emergence" to describe something that comes into existence, but was not known to exist before.

(2) "particles" is a plural noun and should be paired with "are", a plural verb.

(3) If we consider "microplastic" as a substance, it is uncountable. When we use "microplastics", we are considering the different types of microplastic, and it becomes countable. Microplastics are (correct) / Microplastics is (incorrect as you are referring to more than one type)

(Part Three)

(4) We "eat" when we taste and chew our food before swallowing it into our gullet. I used "ingest" instead to describe organisms who take their food by simply swallowing it.

(5) Here, you are stating a claim or a truth. Therefore, you are not referring to a specific group of scientists, and do not need the definite article (the). 

Examples: 

The plants need light to photosynthesise. --> you are referring specifically to some plants you have. / Plants need light to photosynthesise.--> you are referring to all plants in general.

(6) Scientists made their discovery in the past, but the discovery is still relevant at the present. To express this meaning, we use the present perfect tense (have found). 

(7) "News" is an uncountable noun even though it ends with the letter "s". We can, however, add a unit of measure before an uncountable noun and pluralise it. Example: two pieces of news (correct) / two news (wrong) / a news (wrong)

(8) The apostrophe s ('s) is unnecessary as we can use "human" as an attributive adjective to describe the noun "feces". Some examples: Train station. Although "Train" is a noun, it acts as an attributive adjective in this case to describe the type of "station". We do not write "train's station". / Lemon juice. Although "Lemon" is a noun, it acts as an attributive adjective in this case to describe the type of "juice". We do not write "lemon's juice". 

(9) We use "this" to refer to a specific thing just mentioned. (e.g. We are discussing about our budget, and I have a feeling this will take a long time.) We use "that" to refer to a specific thing mentioned some time ago (in the past).
