Q)
How has the recycling practice changed over the years? Did the recycling materials change compared to in the past? Tell me all the changes regarding the recycling system in your country.

A)
Well, about recycling, I don't think many things have changed.
I just throw the can on the can box, paper in the paper box.
oh, one thing has changed!
in the past, I just threw away the box with tape.
but the law was changed. nowadays, I have to get rid of the tape of the box.
Yeah, it is very time consuming. I'm lazy person so I don't like this change.
This is all about what I want to say about this question. =  Well, when it comes to recycling, I don't think much has changed. I just throw cans in the can bin and paper in the paper bin. Oh, but one thing has changed! In the past, I used to throw away boxes with the tape still on them. But the law changed, and now I have to remove the tape before recycling the box. Yeah, it's very time-consuming. I'm a lazy person, so I don't like this change. That's all I have to say about this question.

CORRECTIONS: 

• "Many things have changed" → "Much has changed" (more natural for general statements).
• "Throw the can on the can box" → "Throw cans in the can bin" (correct preposition and natural phrasing).
• "The law was changed" → "The law changed" (active voice is more natural).
• "Get rid of the tape of the box" → "Remove the tape before recycling the box" (clearer meaning).
• "I'm lazy person" → "I'm a lazy person" (article "a" needed).
• "This is all about what I want to say about this question" → "That's all I have to say about this question" (more natural).
