Does this sound natural?

I prefer to buy used books because I have a tight budget. You see, as a student with no income, I really need to save money to pay for my tuition, communication, learning materials, etc. Used books are more economical than new ones.

Besides, I'm a member of an environmental club at my college. Last year I participated in an activity where we collected recyclable resources and then sent them to a recycling center, which increased my awareness of environmental protection. Making full use of paper contributes to protecting trees.
That's why I choose used books.

Thank you!✨✨
