If you talk to me about something that affects deeply the healthy, the life style and the planet in general, i'm instantly think about the climate change that is the hardest problematic in the present, why? Because it's impossible to deal with him, sitting in an armchair texting in Twitter, Instagram or whatever app of instant messages writing about the poor interest of the society for the climate change, the menacing of the resource depletion, the exaggerated dependency of the fossil fuels and the growing industry, actually will do nothing, trust me, instead of that you must be a "green" advocate, in other words, a person who participate in organizations and groups that make management plans, working together with the current administration, to counter or minimize the effect of the climate change and aware the society of this serious problem.
