Of course. The difference may be completely insignificant, but I believe that even if it is insignificant, my actions may influence other people. I notice that in my neighbourhood, many people still do not separate their rubbish correctly. It is unbelievable that in the 21st century there are still people who throw plastic packaging into the general waste bin, when less than 50 metres away there are bins for plastic, cardboard, metal and glass packaging. I believe in a more evolved society, and this is also demonstrated by the respect we have for the way we live and the footprint we want to leave for those who will come after us.
