You can make concrete changes now. Vote with your dollar. Do not support industries that flippantly disregard the beauty and sanctity of life in its many forms.
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.
Whoops, sorry, crimethink!
