Great issue you have raised!

Thank you Yasmin !!

All in all, it's understandable with an exception of a few mistakes. I've added corrections in [] and edited your letter below. Try not to put comma (,) after 'and'. I am writing [this letter/email] because I have a lot of things that I would like to say about your magazine. I [would like to express that i'm very] happy to hear that you will publish some of the letters. First of all, I would say that your magazine is one of the best scientific magazines at the moment. I like the different articles about wild animals and how we can protect them. I also think that it is a great idea to post the opinions of the scientists about the global warm problem. It is an extremely interesting magazine, I love it because I´m not a scientist and they explain all the things in a [simpler] way. In my opinion, I would suggest lowering the price of the magazine a little because it is expensive and it is difficult for me to afford it [every week]. Regarding the content, I think that it would be good to add something about physics and for example, black holes. I will be pleased to hear from you soon.
