I wrote a sentence which my French teacher amended, although I am unsure if either of them are right...
I was trying to say "I am worried about all the environment problems which could destroy the planet", but omitting the 'de' from it makes it seem wrong.
Orginial:
Ça m'inquiète de tous les problèmes environnementaux qui pourraient détruire la terre...
Amended ('de' omitted):
Ça m'inquiète tous les problèmes environnementaux qui pourraient détruire la terre...
Is my teacher right? Or are we both wrong?
