Don't worry, soon you'll fell numb hearing informations like this, like some of us already do.
It used to affect me deeply too, until I realised people truly don't care, especially the wealthy ones that have the means to do something about it.
I'm still doing my part trying to follow the principles I believe in, but if you asked me if I'm going to be shouting from the top of my lungs to warn people that we really are getting to the tipping point, I wouldn't.
The tipping point (for me) was already crossed 15 years ago, and if the masses still don't get it, then they'll never get it.
Enjoy life for what it is, following your principles and being true to yourself, but don't let it bring you down, unless you want to turn into a grouchy old lady, or a man, yelling at clouds.
