Tu peut commencer par introduire Zoella et définir les vloggers:
Vloggers are people whom do video on internet. They can create a video around some topic or they can "vlog", which means that they film themselves during the day.
Zoella is an author and Youtuber. Her channel is mostly about fashion but she has a second channel where she vlogs. She curently has 11 milions of suscribers. She has influence, so I think that those people (whom has a lot of suscribers) can change thing because they have a lot of support behind them. If they use the right point (argument) they can rally a lot of people to their causes.
En gros, tu introduit d'abord Zoella et les vloggeurs, puis tu vas dire que Zoella a 11 millions d'abonnés et qu'elle a donc beaucoup d'influence. Si sa cause est juste et qu'elle a de bons argument elle peut rassembler beaucoup de personne sur un même sujet.
