It is estimated that between 90 and 95% of the indigenous population of the Amazon died after 1492<\/strong>, because, when Europeans first arrived on the coasts of South America, brutal waves of disease, war, slavery and genocide followed.<\/p>\n

<\/p>\n

However, new measurements suggest that, in many places, land abandonment and reforestation began between 300 and 600 years before the arrival of Europeans.<\/p>\n

The Amazon is a vast region in the horizontal and northern part of South America that includes the rainforest of the Amazon River basin.<\/p>\n

<\/p>\n

According to this new study<\/a> published in Science<\/em>Therefore, depopulation and subsequent reforestation in the Amazon began centuries before the arrival of Europeans and did not contribute to the decline observed atmospheric CO2 during the 17th century<\/strong>.<\/p>\n

The data suggest that, in many places, land abandonment and reforestation began between 300 and 600 years before the arrival of Europeans.<\/p>\n

<\/p>\n

To reach these conclusions, researcher Mark Bush and his colleagues at the Florida Institute of Technology, in Melbourne (Australia), evaluated fossil pollen records from 39 places in the Amazon<\/strong> that record changes in forest cover over the last 2,000 years.<\/p>\n

We should cut down fewer trees if we want to reduce the probability of the next pandemic<\/a>\n <\/div><\/div><\/div>\n<\/div>\n

That does not mean, of course, that the cascading effects of environmental change, pre-European pandemics and\/or social strife may have contributed as well. Nevertheless, It is possible that indigenous populations in some areas of the Amazon were already declining when Europeans arrived.<\/strong>.<\/p>\n
