Tourism is causing environmental problems all around the world. What are the main causes of this. What are some solutions.

Tourism indeed plays an important role in a country's economy. However, one of the root causes of the deterioration of the environment is tourism. This is mainly because of the increased number of commercial flights and improper ways of throwing trash. Many solutions can be implemented to cope with these issues. Firstly, greenhouse gases such as CO2 are released into the atmosphere and ocean due to the burning fuel of flights. The Greenhouse gases block heat from escaping from the atmosphere, causing temperatures to rise. Secondly, inappropriate ways of dumping junk are also creating problems for local tourist sites. Take Ha Long Bay as an example; garbage that visitors throw away is stuck in numerous rivers, which has exterminated fishes and birds in surrounding areas for years. As a result, ecosystems have become unbalanced in many tourist sites.
