Message:

Donc en moyenne une plante ne consomme autant d'oxygene qu'elle n'en produit.


Si le truc c'est de garder les plantes jeunes pour produire plus d'oxygene, remplacer la foret amazonienne par des blocs d'habitations avec plein de gazons sera mieux, non ?


Vu que le gazon reste jeune.

Je vais proposer une idee, sachant que je reconnais d'avance qu'elle peut etre fausse:
Pour ce qui est des 30% qui restent, je ne miserais pas sur la foret mais plutot sur les petites plantes. Un arbre c'est beaucoup de masse par rapport a son feuillage, alors que de l'herbe (mauvaise ou non), c'est presque toute sa surface qui est photosynthetique, donc meilleure rendement. J'ai bon ?

En considerant que la photosynthese n'est possible que lorsque le soleil atteint la plante, entre la surface que couvre la canopie d'une foret et mon gazon, en comptant que la foret est composee de plantes plus anciennent alors que mon gazon reste jeune, je dirais que mon gazon produit plus d'oxygene...


non ?

Raf, archange qui est pour le remplacement de la foret amazonienne par des parcs.
