Dear editor,
Environmental problems are becoming more and more serious all over the world.
The first problem is the rise in population. The population is increasing so sharply that there aren't many more resources to use. Because of the large population, a large number of natural resources are overdeveloped. Overdevelopment of natural resources has a negative effect on the environment. And then, cutting down trees from forests is a kind of overdevelopment of natural resources. The trees which are cut down are usually used to make paper or furniture.
What's more, the lack of water resources is always an important problem for some countries. In those countries, many people don't have access to safe drinking water. So many countries are suffering from a lack of water resources. The last one is air pollution. The polluted gas mainly comes from factories and dwellings.
To solve these problems, we must start to protect the environment, such as reducing the waste of natural resources or throwing rubbish into the litter bins. I believe if we do all these well, the environment will be better.

correct_sentence: The population is increasing so sharply that there aren't many more resources to use.
error: much
correction: many
error_type: Determiner Error
error_severity: 2
error_description: Determiner Error: The original sentence uses 〈much〉 to modify the plural countable noun 〈resources〉, which is grammatically incorrect. According to English determiner usage, 『many』 should be used to modify plural nouns, so it is changed to 『many resources』 to maintain number agreement.
error_sentence: And then,cutting down trees from forests is a kind of overdevelopment of natural reasources.
correct_sentence: And then, cutting down trees from forests is a kind of overdevelopment of natural resources.
error: reasources

error_description: ① Spelling Error: The noun 〈courties〉 is misspelled. According to the correct spelling of the noun for 'country', it should be changed to 『countries』, meaning 'countries'; ② Punctuation Error: The introductory adverbial phrase 〈In those countries〉 is missing a necessary comma. According to English punctuation rules, a comma is added after it, forming 『In those countries,』 to separate the adverbial phrase.

correct_sentence: The polluted gas mainly comes from factories and dwellings.

error: the rubbish to
correction: rubbish into
error_type: Preposition Error
error_severity: 4
error_description: ① Determiner Error: The definite article in 〈the rubbish〉 is redundant because 〈rubbish〉 is used here as a generic uncountable noun. According to grammatical rules, 〈the〉 is deleted and 『rubbish』 is used directly; ② Preposition Error: The preposition in the phrase 〈throwing the rubbish to〉 is inappropriately chosen. According to the direction of the action (into a container), 『into』 should be used instead of 〈to〉, forming 『throwing rubbish into』 to indicate the target container of the action.
