蒂茹卡國家公園：為世界上最大的城市森林恢復野性而進行的鬥爭

The Tijuca forest in Rio de Janeiro is a unique and historic place. It was protected in 1861, making it one of the oldest protected areas in the world. The forest has faced many challenges over the years, including deforestation and the loss of animal species. The Tijuca forest is now a national park and is the most visited park in Brazil. It plays a crucial role in regulating the city's temperature and providing a source of freshwater. However, the forest is facing some serious issues. The tall trees are slowly dying and not being replaced, which is affecting the overall health of the forest. Additionally, many of the seed-spreading animals that used to live in the forest have disappeared. This has led to a decline in the forest's biodiversity. To address these challenges, a project called Refauna is working to reintroduce the animals to the forest. While it's a slow and challenging process, the project believes it's essential for the survival of the Tijuca forest.
