i like it, because we as human have improved n developed lot of things, like medicine, science n so on.. but there are some things that still need to be done or eliminated..
1. poverty - not only in Africa but also in big cities.. sometimes we just don't see it - like the favelas in Rio de Janeiro.. it's sad that now, when we can explore the universe or construct nuclear bomb, we cannot eliminate things like that..
2. racism - all kinds. discrimination against skin color, sex, religion or whatever. it's XXI century and people still cannot get rid of such prejudices..
grow up, people..
3. it's money-oriented world. sometimes we forget about friends n family to earn more money, we kill for money, we do everything to show off..
4. natural enviroment - we just have to think about the world we live in, because in xxx years it's gonna be really hard.. deforestation, air and water pollution, natural resources..
we really have to do something, cause it may be too late one day..
