Are tourism resources renewable?

Tourism resources, except animals and plants that can be artificially cultivated and propagated, can be said to be non-renewable resources, and once destroyed, they will no longer be owned. For example, the number of ancient buildings on the ground is always decreasing and will decrease day by day. Gandan Temple has a history of more than 600 years and is one of the three famous temples in Lhasa, Tibet. Razed to the ground at 1969. Jinan, the spring city, used to be a beautiful scene of "every family weeping willows every spring", but it no longer exists because of the lack of protection of water sources. Even the famous Baotu Spring and Pearl Spring are on the verge of water shortage. This non-renewable nature of tourism resources determines the importance of its protection. The huge demand may be an irresistible temptation to the development and sales of tourism products, but it may also be an immeasurable potential destructive force to tourism resources. Some people emphasize that tourism resources can be used permanently. It is worth pointing out that the sustainable utilization of this kind of tourism resources is limited by various conditions. For example, limestone caves, even if tourists are highly civilized and consciously maintain the cave environment, if the cave capacity is not controlled, too many tourists will flood in, which will change the cave microclimate and accelerate the weathering and destruction of chemical deposits in the cave.
