Memory Game Memoria: Ser Humano y SustentabilidadOnline version Descubre conceptos clave sobre la relación entre el ser humano y la sustentabilidad. by HECTOR GARCIA Today we expect to live to be about eighty. Everything was infested with insects and rodents. Most of our ancestors lived in huts with dirt floors and thatched roofs. They made a lot of their own clothing. The astonishing growth in prosperity is one of the greatest events ever. They built their own dwellings. We grow to be four inches taller than we were just 250 ago. The filth was horrible and often toxic. Our ancestors ate gruel There were no toilets. They wore the same home-made underwear over and over. The enrichment of the last centuries is the hockey stick of human prosperity Streets and alleys were open sewers. Today it is more like 1 in 200. One in four kids would die before the age of 5. Smallpox was eradicated in 1977. Life expectancy was around thirty years. They grew most of their own food.
