At friday I read a book about 31 things how to change the world! Its a really great book. It explains about things how to prevent bad things going to happen to the world such as, no clean water left. One of the example to prevent it is to don't sing in the shower too long because a lot of water will be pumped to the filter  and will be pumped again to your shower but not all of it is going to be used and the left overs will be stored into a different pump where its going to be for the dirty water, well your left over shower water is still clean. this book inspires me to do the right things to the world and to respect other cultures because in that book tells us about the facts of different celebrations from different cultures. Its a really decorative book and a it has a lot of fun facts in it you should try to read it in the GJIS library.
