Нужно рассказать в пяти-шести предложениях почему indoor climbing (скалолазание в закрытом помещении) более популярно чем outdoor (на свежем воздухе,на горе например) . например более безопасно,интереснее и т.д. буду - : )

Indoor climbing is more popular than outdoor climbing. Outdoor climbing is dangerous and risky, because you can easy die on a mountain. Also it's much harder than indoor climbing, in a gym you can stop climbing at any time. But on a mountain you can't just stop, that's why indoor climbing is more popular than outdoor. In a gym you are in a safe. So I will choose a indoor climbing.
