How does the rising sea level influence erosion?
JC: Actually, the sea level rises just three millimetres per year, but the important thing is the domino effect: there are more coastal currents that cause erosion, and it is raining more in some places, and that carries soil towards the sea, which modifies ecosystems. It is estimated that in 2025 there will be one billion more people on the planet and a notable shortage of food, because the key ecosystems will have collapsed. Ecosystems can adapt, but they need more time. By 2025, the United Nations calculates that 85 percent of the world’s population will be living in coastal areas, which are inherently unstable and will suffer even more from human pressures. And there is another problem: pollution. A 1,000 to 1,200-metre stretch of the Ro de la Plata coast in this country is contaminated with mercury, cyanide, chromium, detergents, etc., from waste that is not treated because it would be very expensive. Fourteen million people in this country drink water that comes from the Ro de la
