The content is okay but there are 3 grammar errors or omitted words in your first four sentences. More attention to detail and better English is needed. I'll approve this just because of the content.

This is borderline. You'll have to take more care with your sentence construction as parts of the article reads very clumsily. Also focus more on expanding on specifics instead of just saying "and so on".
