It's an important start, but sometimes it just feels like it's not enough, especially if people have certain beliefs that they hang onto without being able to defend them, for fear of a slippery slope situation. Take for example smoking. It's absolutely disgusting how they just throw their cigarette butts on the ground when they're done with them. So, not only is it a harmful activity to engage in for the individual at hand, it also harms people nearby, as well as the environment as the trash they leave behind is not biodegradable. No idea what can be done about this.
