before today

Lanina, a small town in Argentina, used to attract huge numbers of tourists every year. The weather there used to be mild with warm winter and cool summer. It was many series of animals and plants that impressed travellers deeply. It is no wonder that tourists considered it as the heaven in the world and everything there seemed to be in a perfect condition. However, a disaster was on the way. It was not until several years ago that local people realised it. Floods and sandstorms continued attacking the town, leading to the spread of diseases and the destruction of species. As a result, people there had to move out of the town.
