National parks - how do they help the environment?

Hello

National parks are a place of immense beauty. They are know as tourist attractions and are best recognised by their incredible landscapes. Today we are talking about their effects on the natural world!

National parks are normally created and protected by governments. In most cases, they have public access, meaning that visitors can walk around in them and admire them. The IUCN defines what is a national park and what isn't. In 2006, over 6 500 areas met the criteria and are defined as a national park. However, there are many areas called National Park, that aren't a national park according to IUCN and there are places that the IUCN defines as a national park but the government doesn't. So some countries have their own definitions. In the UK and some other countries, a national park referes to an undeveloped, scenic, tourist attracting area that has some planning restrictions. This may seem quite subjective, because there isn't really a scientific definition for scenic. So the term, national park is not very firm or well defined. Terms such as "preserve", "reserve" and sometimes just "park" are also used.

The world's oldest national parks include Yellowstone National Park (United States), Tobago Main Ridge Forest Reserve (Trinidad and Tobago) and Bogd Khan Uul Mountain (Mongolia). Following the IUCN definition, the smallest national park is the Isles des Madeleines National Park (0.45 squ.km) and the largest national park is the Northeast Greenland National Park (972 000 squ. km).

National parks have many benefits for humans. They bring in massive numbers of tourists, which is highly beneficial for the economy. In the US in 2019, the national parks brought in 41.7 billion dollars for the US economy. They also produce hundreds of thousands of jobs and boost the economy on a local level as well as nationally. Having an accessible green space is also known to have amzing health benefits especially for people living in crowded cities and large towns. They are also a research opportunity for scientists and have a great educational value for pupils and students.

Above all else, national parks are amazing for the environment. They protect ecosystems, help critically endangered species to recover, protect and improve air quality, host biodiversity, often store carbon, protect natural ressources, stabilise soil, reduce flooding, protect coastlines and sometimes even generate renewable energy. One of the most well known projects, is when wolves were reintroducted into Yellowstone National Park (United States) in 1995. The wolves tranformed the entire ecosystem and even changed the course of the rivers. Watch the video here.

However there is some critism at national parks. This mainly comes from the fact, that when many national park were created, the indigenous people living there were forced to move. This has led many people to say that certain national parks are a symbol of colonialism and should be returned to their previous owners (the indigenous people). Many governments and organisations are organising for the indigenous people to be allowed to live in their ancestrial lands and are often encouraged to continue with their traditions. Now they are often included in the tourism sector and many indigenous people in national parks work as guides or performers and help with the conservation of the land.
