english: It's true, we may have charted all the continents on the planet and we may have discovered all the mammals that are out there, but that doesn't mean that there's nothing left to explore on Earth.
non_english: Možno sme už preskúmali všetky kontinenty a poznáme všetky cicavce na Zemi, ale to neznamená,  že tu už nie je čo skúmať.
