One fifth of human kind depend on fish to live. Today now 70 percent of the fish stock are over-exploited. According to FAO if we don't change our system of fishing the main sea resources will be gone in 2050. We don't want to believe what we know.

The fact is that seven per cent of the global population emits 50 per cent of greenhouse gas emissions, and the proportions are the same for the use of energy and raw materials, meat, wood, etc. Simply put, an infinitesimal minority consumes the most and imposes damage on the overwhelming majority, while asking it to change.
