Hello,
Explications :
-The people made (verbe FAIRE au PASSE) the Earth Day in order to be aware of the environmental situation.
-Them cartoons make me think about their bad habits.
-The polars bears are (verbe ETRE au PRESENT) more vulnerable to extinction because of the global warming.
-The documentary made us cry (verbe PLEURER à l'INFINITIF car make= made qui est déjà conjugué du coup).
voilà :)
