Pollution and Hygienic Problem Solid waste is a serious problem everywhere, and it affects the local environment a lot, especially on the celebration day. Many tourists go to Japan for the Hanami in spring. But after they finished, they littered in the planted area. Tourism damage the world heritage sites as well. Visitors wash feet in the public places such as the Louvre and the fountain water in Rome. They attempt to destroy the ancient monument and spray graffiti on trees or the heritage. The urine, vomit and feces were left around the sites. The rubbish and fecal matter contaminate the soil and pollute the air. It provides a breeding ground for insects and affects the local people directly. It makes the locals take a lot of time to clean it up. Animals may be trapped in the rubbish or they may eat those hazardous things.
