Since when do we have national parks?

The 19th century saw the emergence of a general concern to protect the wonders of nature. The first protected areas were set up. The Yellowstone National Park, the world’s first protected area, was established in 1872 in the middle of the Rocky Mountains. Here, an attempt was made to retain the unique landscape along with the diverse flora and fauna. This idea was soon adopted by Canada, Australia, and New Zealand, who also converted extraordinary habitats into national parks or wildlife sanctuaries. Today, there are around 2200 national parks in 120 countries.
