Les élèves des écoles francophones hors-Québec devraient pouvoir utiliser toutes les langues qu'ils connaissent en classe, au lieu de se les voir interdire.
Afin de favoriser l’apprentissage du français en milieu minoritaire au Canada, il faut promouvoir l’utilisation et la conscience des autres langues parlées par les élèves, dont l’anglais.
These insects are basically little machines that convert carbon-rich leaves into nitrogen-rich poo.
As environmental engineers, invasive caterpillars can have remarkable effects on water quality and soil conditions. But from a climate perspective they’re pretty much a nuisance.
