@senseicat There two worlds, the first one you can not change, only God The Creator can do that, but you can help to make it better, How: Fighting against global warming lets say desconectig the cells phone when they are not in use, planting trees, not using the fracking, saving energy, not contaminating the waters etc.
The second world are the human beings and it is the most difficult world to change but I have always thought that the only way to help people to be better is changing yourself and showing people you are different and that the things you do are worth imitating and that the way you behave, it pays well. Come and do what are do. I give you an example, There was a little girl very hungry walking along the road where I live, someone gave her a cup of soup but running spelt the soup and she started to cry so loud and so sadly that neighbours came out an they felt pity for her and didn´t do anything, my husband filled the cup with rice and I gave her a bread with cheese. The smile came back to her face. We need to be differet and distint to help others that it is worthy to live in this decadent worl.
