Soluzione

  • Bill: I'm worried about pollution.
  • Andy: What exactly do you mean?
  • Bill: What I'm trying to say is that each of us should blame ourselves for the tons of waste we produce every day.
  • Andy: That's right, and some kinds of waste will take years to disappear. If I've understood correctly, using glass bottles could be a good alternative because it's possible to recycle them.
  • Bill: And we should also consider alternative energy sources.
  • Andy: Can you clarify that?
  • Bill: In other words, renewable energy comes from natural resources like the sun or the wind, which are always available and inexhaustible.
