Nu cred ca biomasa s-a modificat in cantitate, doar in calitate.
Pentru ca ai o viziune prea simplista asupra problemei. Poate e nevoie de statistici care sa acopere direct problema in discutie:
"There is a lot of talk about loss of biodiversity but very little is said about the loss of total biomass
. A huge amount of evidence exists to show that the overall biomass on land has been massively reduced over the past 3,000 years and increasingly evidence is coming to light in respect of the loss of biomass in the oceans. Loss of biomass on land may well be as great as 50%, loss of biomass in the seas could be as high as 80%.
If this is correct one of the consequences of man’s actions over the past 3,000 years
is that the overall annual living carbon cycle has been massively reduced by perhaps as much as 70% of what it would have been over the preceding four million years."The Gaping Hole in Earth System
Si la asta se adauga efectele distrugerii biodiversitatii asupra intregului ecosistem.
