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!
Yosemite National Park, United States
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.
Cairngorms National Park, Scotland
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.

Coral reefs

Hello! We would love to introduce you to the topic of coral reefs and especially coral reef bleaching, as it is a greatly ignored but certainly significant topic. Have fun! 5 coral reef facts 1. The Great Barrier Reef is the largest living structure on the planet and is 2300 km long! 2. Less than 0.1% of the world's ocean surface is covered in coral reefs. 3. At least 25% of all marine animals live there. 4. Coral reefs are often known as the rainforests of the ocean. 5. In 1 square kilometre of coral reef, up to 35 tons of fish can be 'produced'. The 5 biggest coral reefs in the world 1. Great Barrier Reef (near Australia) 2. Red Sea Coral Reef (near Egypt, Israel and Djibouti) 3. New Caledonia Reef (Pacific Ocean near New Caledonia) 4. The Mesoamerican Barrier Reef (near Mexico, Belize, Guatemala and Honduras) 5. Florida Reef (Atlantic Ocean/Gulf of Mexico near Florida) What is coral? Coral is actually made up of small anim...

Energy comparison: solar (PV) panels

Hi everyone, Today I'm looking into the first on a long list of energy sources: solar (PV) panels. Are they actually sustainable and could they become our main energy source in the near future? After all, enough energy from the sun reaches the earth in 90 minutes to cover the entire world's energy consumption for a whole year! How they work There are a couple of ways to transform energy from the sun into electricity. The one we are looking at today is solar panels also known as solar photovoltaic technology. Photovoltaic (PV) technology is the key to solar panels. A solar panel is made of many PV cells. A single PV cell will produce 1-2 watts of power. They are very thin and are normally protected by glass and/or plastics. This is the best explanation I could find (click here for the source): When the semiconductor is exposed to light, it absorbs the light’s energy and transfers it to negatively charged particles in the material calle...

Animals 31-35 in our '50 incredible animals' series

Hi Everyone! Welcome back to our blog, today we are sharing another 5 incredible animals. This is part of a series to celebrate our 50th blog post, all about unusual animals! Enjoy! 31. Pangolins These creatures are often mistaken for reptiles but they are in fact mammals. They are covered in scales and use them to defend themselves because similar to a hedgehog, they curl up into a ball. They eat ants, termites and larvae. They eat using their tongue, which is very long- sometimes even longer than their body! Sadly, Pangolins are in high demand as their meat is considered a delicacy their scales are used in traditional folk remedies, which means that there is an illegal trade. Luckily, there have been many initiatives put in place to help these animals by WWF and similar organisations. 32. Macropinna Microstoma This is a species of fish that live at about 600m below sea level. They hang nearly motionless in the water and have a very unusual...

The life of ... a cicada

Hi everyone, We're back to talk about another animal. Cicadas ( Cicadoidea ) are invertebrates and are 1.9cm to 5.7cm in size. There are 3 000 species that can be divided into annual cicadas and periodical cicadas. Annual cicadas can be seen annually and are found worldwide whereas periodical cicadas only leave the ground every decade or two and are only found in North America with hotspots in the eastern and central areas of the United States. Most annual cicadas have a lifespan of about two to five years and periodical cicadas can live up to the age of 17. Female cicadas lay around 400 eggs split up over several places. They normally lay their eggs on twigs, branches or other vegetation. The eggs hatch after about six to ten weeks, now known as nymphs, and dig their way into the soil. The nymphs feed on the liquids found in plant roots. They fully develop underground, before molting their shells and coming to the surface, now fully deve...

10 Animals on the Edge of Extinction No. 10- The Javan Rhino

The Javan rhino is listed as the 1st animal on WWF’s list of the 10 world’s most endangered animals, and I for my part, had never heard of it! If you hadn’t either, we’re changing that now.  A bit about the rhino’s lifestyle The Javan rhinos are now exclusively found on the island of Java in Indonesia, but were once found in vast regions of northeast india and Southeast Asia. They have a dark grey colour which looks almost black when wet, and their (often pink) skin folds look a bit like plated armor. Both males and females have lower incisors which resemble tusks that they use to fight. Males have one relatively short horn of about 25 cm (10 inches).  Javan Rhinos live in tropical forests, marshy areas and in the thick bush. They are mainly browsers and eat over 100 plants species they find in the forest, weigh between 900 and 2300 kg (1984-5071 pounds) and are between 3 and 3.2 meters (10- 10.5 feet) long.  How endangered are we talking?  Javan rhinos are the most ...

Heatwaves - what's so bad about them?

Hi everyone, Today we’re talking about heatwaves and what effects they have on us and the environment. Heatwaves are becoming ever more common, with 2023 breaking multiple world records. In China, 52.2°C were recorded at one point and the coastal waters near Florida, USA, were as warm as a hot tub. This is because of the combination of climate change and El Niño , both of which make the effects of the other worse. But we can’t push the blame onto El Niño. When analysed it became clear that without human made climate change the USA heat records would have been almost impossible. So what exactly are the effects of such high temperatures. A study in Europe found that the 2022 heatwave possibly caused over 70 000 heat related deaths. Although it is sometimes hard to tell whether or not someone died from the heat or from something else, after analysing the data the team found that their original estimate of 62 000 people (which is still a lot) was probably ...

18.10.20 Animal Of The Week: Sloth

Hello, Sorry this didn't come out on Sunday as planned but this week's animal of the week is the sloth because the twentieth of October is Sloth Day.  Habitat The sloth resides in Central and South America. It lives in the rainforests there and occasionally drops into the water for a bathe as, believe it or not, they are actually excellent swimmers! Diet Sloths eat leaves, twigs and buds which they find in the rainforest. As they don't have incisors they smack their lips together to make leaves more digestible. Sloths can survive on relatively little food as it takes a while for them to digest it. Sleep and Speed When you think of a sloth, you probably think of this slow, sleepy creature. They actually sleep for about 15 hours a day! Sloths have an extremely low metabolic rate (what basic calories your body needs to survive), which means they move at a slow pace through the trees. On average, sloths travel 40 yards per day ...

February 2021 Factfile - a bit of news from the last month and more!

Hi Everyone! Welcome to February's factfile! We are very sorry that we have not posted very much so far in 2021 but we are going to hopefully make up for it in the spring. News: Source- BBC Newsround The great yellow bumblebee has been spotted in Scotland! They used to be common in the UK but their population declined by about 80% in the last century. The find is a spark of hope as it is currently endangered. This is thought to be because of a decline in natural flower meadows and a boost in farming. The team of conservationists that found it were thrilled and when we heard about it we wanted to share it with you in case you hadn't heard! Source- Guardian In the 1840s a bird was caught in the East Indies. It had never been seen before and Charles Lucien Bonaparte (Napoleon's nephew) named it the black-browed babbler. The species wasn't seen again, so the only proof that it had ever existed was a stuffed specimen. ...
