Children's SDGs: A Book to Understand Why SDGs Are Necessary Supervised by Kojiro Akiyama / Written by Bound Every year, I choose one topic from this book for my summer vacation assignment and research it in detail, which saves me from struggling with the assignment for six years. In the year of animal and plant extinction, I researched the Yanbaru Rail. The following year, I researched the Iriomote Cat in detail. I think it will be a good opportunity to learn something. It's in good condition, but it's used, so it's not suitable for those who are concerned about minor details. It will be placed directly into a bag or envelope.
