Imagine if the world were a village. A village of a 100 people. There are many things you do not realize that can occur in this village. For example, in 2150, there will be too many people living in the village. 100 is the max, which means the world will be too small for all of us to live in and it surprises me because I never thought of our own world being too small to fit all the people in it! This book talks a lot about things going around the world that we don't even realize. It takes the perspective of a world as 100 people and uses that as a way of counting people for religion, water we get, what we speak, and many more. I think most of these are SUPER important to the world and the future. A great example for this is that 62 people have access to have a place to put waste and garbage. However, 38 do not, which can cause diseases and that upsets me because we all NEED somewhere to do this. That is a good example because it describes how important the future is. If we don't find a way to fix all the problems the book states, then our future could be in trouble. Speaking of trouble, another problem we need to fix is that 87 people have access to safe water. But, 13 do not and I wish this wasn't a problem because it is so important to get access to this or you could die. Luckily, we can help because company's run charities that we can help to help end this!. We need everyone to get safe, clean water and they should be able to get it easily. I think that diseases are really important to consider, like when I talked about the waste not having a place to go to. Another thing the book states about diseases is that 68 people breath clean air. 32 people do not get good, clean which can cause diseases for people. I think this book is a great example of how we need to take care of our planet because it gives you the perspective of a world of 100 people which makes you realize and consider problems that we face and will face in the future.
