My home is my castle - Belarus
“My home is my castle!” the English say. It means you take care of your home because it gives you the sense of stability. You keep it tidy, you decorate it, give it a kind of repair from time to time. If you consider yourself a global citizen you should do the same with your home and your home is the Earth.
Do you remember the “Little Prince” by Antoine de Saint-Exupery? I think that it’s the right image of a global citizen – this little boy. He knows that there would be no other home for him and he loves his planet with all his heart, though the planet is very small.
So, in my opinion, if one takes the whole Earth as his home, tries to protect it (to say nothing of not destroying) he may consider himself a global citizen. What do you think about it?
