Floods. Droughts. Storms. Pollution. Nowadays, we read about numerous threats that weaken and spoil our earth, and deplete it of its resources, on a daily basis. Not to mention the poor state in which we are leaving the world for subsequent generations. Of course, even we are able to see the growth in the population with the exponential increase in consumption. Yes, ice caps are melting and the hole in the ozone layer isn’t getting any smaller. Indeed, the supply of raw materials is diminishing and is down to its last reserves. All of this leads to two options: Do we give up on earth? Or do we give earth a new future?

The companies of Ortessa.
