MACARENA: Hola, José. ¿Qué tal tu viaje a Costa Rica? JOSÉ: Estupendo. Mi novia y yo pasamos una semana en las [q5] en el interior del país. Nos gusta mucho la playa, pero también nos encanta [q6] en caminos bonitos. MACARENA: ¡Qué bien! No sabía que os gustaba caminar y hacer vías ferratas. JOSÉ: Bueno, somos principiantes, pero es que hay muchas actividades para hacer allí… Nuestra excursión favorita fue cuando exploramos una [q7] con linternas. También nos encantan los animales y pudimos [q8] a caballo y [q9] las aves desde una distancia recomendada. MACARENA: ¡Me alegro! Estoy pensando en mis próximas vacaciones y quiero ir a un destino como Costa Rica, donde cuidar la [q10] es muy importante para el turismo. JOSÉ: Sí, ¡Costa Rica es un destino perfecto! El gobierno y la industria turística trabajan juntos para limitar la [q11] que dejan los turistas.
