Learn spanish or catalan with environmental content

I'm from Barcelona! I've 29 years old and i'm catalan native.

I speak spanish and catalan. I teach content about environmental world, climate change or some things that interest you about this topic in Spanish or Catalan to perfect this languages!! Is so funny, productive and effective. Tell me if you have some questions.

I adapt my class (level, content, type of class, etc) about the person who wants. My class are interesting content documents about enviromental (biology, ecology, climatology, history of the environment and others), do a speacking class together talking about climate change, climate strikes, goverment, how we can change, what could we do... Sometimes i put tasks about permacultura, agricultura, etc because is an interesant and good point to change the world and reduce the climate change...
