environmental problems that affect us. We have global warming, climate change and so it could continue with several others. It is a problem that affects us all equally. We have people who try to do the possible to reverse the situation in which our planet is in a critical state and we have people who simply make the view fat and I ask you a simple question. It is the only planet with life. What are they waiting for to make this great change? With a little bit of sand we can do great things. Environmental problems that affect us very soon by stereo app. I wait for you.
