De acordo com o ecologista William Rees, a m\u00e9dia global \u00e9 de 5.4 acres por pessoa. Mas o planeta tem apenas uma superf\u00edcie bioprodutiva de 4.4 acres para cada um de seus 6.8 bilh\u00f5es de habitantes. A eco-pegada da civiliza\u00e7\u00e3o humana j\u00e1 est\u00e1 22% al\u00e9m do sustent\u00e1vel. <o:p><\/o:p><\/span><\/p>\n<p><span style=\"font-family:'Arial','sans-serif';\"><o:p><\/o:p><\/span><\/p>\n<p><span style=\"font-family:'Arial','sans-serif';\">Estes dados fazem parte de uma interessante e did\u00e1tica mat\u00e9ria sobre ambiente do site How Stuff Works (Como as Coisas Funcionam). At\u00e9 hoje na hist\u00f3ria humana, diz a mat\u00e9ria, esta fome insaci\u00e1vel levou \u00e0 extin\u00e7\u00e3o de incont\u00e1veis esp\u00e9cies, dos mamutes da Era do Gelo at\u00e9 os tigres da Tasm\u00e2nia, no s\u00e9culo 20. <o:p><\/o:p><\/span><\/p>\n<p><span style=\"font-family:'Arial','sans-serif';\"><o:p><\/o:p><\/span><\/p>\n<p><span style=\"font-family:'Arial','sans-serif';\">Tranformamos desertos em terra agricult\u00e1vel, e gargantas em lagos. Mesmo a atmosfera se transformou devido \u00e0 fome por recursos. Muitos cientistas datam a mudan\u00e7a do clima por influ\u00eancia humana na revolu\u00e7\u00e3o industrial dos anos 1800. Outros, como o cientista ambiental William F. Ruddiman, insistem que as concentra\u00e7\u00f5es de CO2 come\u00e7aram a aumentar 8 mil anos atr\u00e1s, por pr\u00e1ticas agr\u00edcolas com o uso de queimadas. <o:p><\/o:p><\/span><\/p>\n<p><span style=\"font-family:'Arial','sans-serif';\"><o:p><\/o:p><\/span><\/p>\n<p><span style=\"font-family:'Arial','sans-serif';\">Al\u00e9m do empreendimento humano, os conflitos tamb\u00e9m alteraram o ambiente.
