Visualizing How A Population Grows To 7 Billion

Visualizing How A Population Grows To 7 Billion
7 Billion: How Did We Get So Big So Fast? Watch as global population explodes from 300 million to 7 billion. Sometime Monday, the world will have more humans than ever: 7 billion, according to the U.N. The U.N. estimates that the world's population will pass the 7 billion mark on Monday. Much of that growth has happened in Asia — in India and China. Those two countries have been among the world's most populous for centuries. Due in part to that region's extreme poverty, infant mortality rates are high and access to family planning is low. As NPR's Adam Cole reports, it was just over two centuries ago that the global population was 1 billion — in 1804. As higher standards of living and better health care are reaching more parts of the world, the rates of fertility — and population growth — have started to slow down, though the population will continue to grow for the foreseeable future.

Evolución de la población. 3.1 Evolución histórica de la población. A lo largo de la historia la evolución de la población no ha llevado siempre el mismo ritmo de crecimiento que hay actualmente (Gráfico 3). Una vez establecidos estos cambios, la población se estanca, creciendo con altibajos y muy dependiente de las catástrofes naturales y humanas como epidemias, malas cosechas, guerras, etc. No es hasta el inicio de la edad moderna cuando la población comienza un ligero aumento, llegando a los seiscientos millones en el año 1600, siendo aun un crecimiento catastrófico. El segundo momento histórico importante para el crecimiento de la población lo encontramos durante la Revolución Industrial. Gráfico 3.

El neolític | La prehistòria El Neolític va ser una època en que els homes prehistòrics van descobrir moltes coses que els ajudaren a viure millor. Anem a conèixer com va anar canviant la seva vida. Quan comença El neolític comença fa 10.000 anys abans de Crist. La vida de l’home neolític Com que eren sedentaris, vivien en cabanes, i en petits poblats. L’alimentació Els homes i les dones del Neolític, s’alimentaven principalment de les plantes que conreaven: cereals (blat, civada, sègol, ordi…) llegums (llenties, ciurons, pèsols…); encara que no van deixar de recol·lectar fruits silvestres. Sergio de la Rosa i Qamar Les seves eines. La destral: L’utilitzaven per construir cabanes i estava fet de fusta i de pedra. La falç: S’utilitzava per tallar el blat i estava fet de fusta i dents Les pales: s’utilitzava per fer forats a la terra i estava fet de fusta. Aixada: S’utilitzava per cavar la terra i estava feta de pedra i de fusta. Molins de mà: s’utilitzava per moldre el gla i estava fet de dos pedres. Raúl Pérez Boyer
