Global ecological footprint: since the 70s we demand more that what the planet can regenerate, global average footprint per capita is 2. 8 gha (hectares per person, global average biocapacity is 1. 8 gha. Earth overshoot day: from this week, everything we consume for the rest of the year is stolen from the how much we have (bio-capacity)? how much we use (ecological footprint)? future. Boundary crossed #1: biosphere integrity - loss of biodiversity, vertebrates populations - 58% decline (1970 and 2012, on the edge of the 6th mass extinction. Boundary crossed #2: nutrient pollution mainly from agriculture and livestock, phosphorus and nitrogen, water pollution.
