What changes have been brought about by the development of alpine tourism? Try to talk about changes from the following three aspects.
Alpbach, a tourist resort in the Austrian Alps, holds an expert seminar on local environmental and ecological issues every year. This year, experts did not discuss the problem of global warming too much, but called for defensive measures to protect the residents of the Alps. Because melting glaciers will cause floods and threaten the safety of local residents.

In addition, the Alps attract skiers from all over the world every year and earn millions of dollars for local tourism. If the snow continues to decrease, it will inevitably affect the development of local tourism.

Scientists explained that human production and life emit a lot of carbon dioxide into the atmosphere, which destroys the ecological balance of nature and causes global warming, thus causing a series of problems. Glacier melting is one of them.

European countries are very concerned about climate warming. A well-known car club in Austria called on office workers to walk or ride bicycles to work as much as possible and drive less cars. Because even in a country with a population of only 8.2 million like Austria, the amount of carbon dioxide emitted by passenger cars reaches 1 1.4 million tons every year. Statistics show that about one-tenth of private cars have a mileage of less than 1 km at a time, and the club thinks that owners can walk or ride instead of walking. As an Alpine country, Switzerland is extremely vulnerable to climate change. Therefore, Switzerland indicated that it will fully support the conclusion of an international agreement on climate policy in 20 12 years, in addition to measures such as taxing carbon dioxide emissions in China.

The Spanish government has implemented a series of policies to promote the development of renewable energy, including providing risk protection support for investment in the development of renewable energy; Subsidize the production and sales of renewable energy.

At the same time, out of concern about the phenomenon of warm winter, some European environmentalists also asked the organizers of the World Cup skiing competition to cancel the competition to protect the snow on the mountain.
