Final answer:
The order of seriousness for factors causing damage to man-made wonders in Vietnam is: stolen valuable things, construction around the wonders, restorations changing the structures, lack of long-term protection from severe weather, and excessive tourism. Poorly managed tourism can also have significant negative impacts.
Step-by-step explanation:
The things that have caused damage to the man-made wonders of Vietnam can be put in order of seriousness and additional factors can also be considered.
Here is the order of seriousness:
- e). Many valuable things have been stolen from man-made wonders: This is the most serious as it involves the loss of important cultural artifacts and heritage.
- a). Many roads, hotels, factories, etc., have been built around man-made wonders: This can cause physical damage and visual pollution to the surroundings of the wonders.
- d). Recent restorations have changed the original structure of some man-made wonders: This may alter the historical and architectural integrity of the wonders.
- c). Local governments don't have long-term measures to protect man-made wonders from severe weather conditions: This can result in gradual deterioration and erosion of the wonders.
- b). Too many tourists visit man-made wonders every day: While tourism can bring economic benefits, it can also cause wear and tear on the wonders and lead to overcrowding.
Additional factor: Poorly managed tourism can cause environmental havoc and endanger local cultural traditions, which can have long-term negative impacts.
