Humankind ecosystem destabilization

In the article "Humans changed the ecosystems of Central Africa more than 2,600 years ago" published in Science Daily, the main purpose reflects on the real cause of the rainforest crisis in southern Cameroon, which was assumed to be a result of climate change (decrease in precipitation amount, increase in precipitation seasonality) , but new controversies claim that the actual cause was humankind. At the top of this controversy, the researcher Mr Garcin claimed that after isotope analysis that there was a major change in vegetation but it had nothing to do with precipitation because it cannot be explained by a climate change. The author states that the main cause would be the increase of sites, resulting in a rapid population growth and new appearances of oil palm use and iron metallurgy. Therefore, after sediment research it was found by Dirk Sachse that humans left anthropogenic footprints in geological archives and it was due to settlements and exploitments of the land. Garcin's research also shows that ecosystems have strong regenerative abilities.

In my opinion, humankind does indeed cause trouble to ecosystems, but the population from southern Cameroon 2,600 years ago had survival and settlement needs and maintaining a good ecosystem should not have been one of their main concerns, even though research proves that it is due to their actions and not climate change. As the article mentionned in the end, the same ecosystem destabilization occurs in other lands, such as south America and Asia, and in 2018 it should be an important concern to have research conducted in order to find solutions.
