First, we have to fix the data, id est the quantum of fluxes:

Secondly, we have to underscore the uncertainty in models:

Third, the species extinction and climate change relationship should be investigated carefully
Apart from technological advances aimed at intelligent management of the flows of different species, which is not the case today, the main resource we have is to leave the important surfaces on land as at sea or the cycle. species predation and renewal is poorly disturbed by humans.
This is what was initiated with large nature parks. If in spite of this the disappearance of the species is confirmed at the pace which is advanced by the ecologists it is necessary to find other solutions but above all, it is necessary to be certain of the diagnosis.
Fourth what are the differences between CO2 and CH4?
However, methane degrades in the atmosphere relatively quickly — it has a half-life of about ten years — whereas CO2 is cumulative, that is to say, a single emission of CO2 will remain in the atmosphere for many hundreds of years, and a series of them will accumulate, continually increasing the amount of global warming (https://www.oxfordmartin.ox.ac.uk/downloads/reports/Climate-metrics-for-ruminant-livestock.pdf).
Cependant, le méthane se dégrade assez rapidement dans l'atmosphère - sa demi-vie est d'environ dix ans -, alors que le CO2 est cumulatif, c'est-à-dire qu'une seule émission de CO2 restera dans l'atmosphère pendant des centaines d'années. s'accumulera, augmentant continuellement la quantité de réchauffement climatique.
