Biodiversity

Hello,

Today we're talking about biodiversity and why it's so important. As you probably know biodiversity describes the variety of living species, often referring to one specific place or ecosystem. For example, the Amazon rainforest is a very biodiverse ecosystem. The opposite of biodiverse is a monoculture. A monoculture often refers to farmland, where only one crop is produced. Palm oil plantations are normally monocultures, with rows and rows of palm trees and nothing else.

I'm going to start by giving you an idea of the current situation. This year, the State of Nature 2023 report was published. This report looks at recent changes in biodiversity in the UK. To be frank, it's bad news. One in six (17%) of all UK species and almost half (43%) of bird species are at risk of extinction. 31% of amphibians and reptiles and 28% of fungi are also at risk. There has been a 54% decline in flowering plant species and a 34% decline in pest controlling insects (insects that eat/kill "pests"). This is mostly due to us humans. Habitat loss, diseases spread via factory farming (like avian flu), variability in climate due to climate change, intensive farming and unsustainable fishing are all contributing to these shocking numbers. Only 20% of farmland is considered eco-friendly and only 44% of woodland is sustainably managed, not always successfully. Only 7% of woodland, 25% of peatland and none of the seafloor that was assesed is in a good ecological condition. Especially the seafloor has suffered from habitat destruction due to fishing gear. But, there was some good news. The conservation work that is being done is paying off. Lyme Bay marine protected area, in Dorset and Devon, South-West England) has seen a increase in biodiversity since trawling was banned in 2008. The RSPB's (Royal Society for the Protection of Birds) Hope Farm has proven that it is possible to produce food and have a 177% increase in breeding birds over 12 years. The improvement of water quality, has made the recovery of freshwater fish species possible.

So, we've already established that biodiversity is declining. This isn't only happening in the UK. It's happening everywhere across the world. And we've already covered some of the reasons for this decline. But is it actually a problem? What are the consequences of biodiversity loss? Probably the biggest problem is the spread of diseases. In a less biodiverse world, dominant species become more and more abundant, and with them whatever viruses and diseases they happen to carry. This has been seen in mosquitoes. The variety of different mosquito species is declining and those that can survive are reproducing more and more and carrying deadly viruses to more and more areas, where they can transfer to humans. Also, monocultures attract certain species like rats, mice and bats. These species are known to generally carry a lot of diseases. Another problem is something that farmers have none about for thousands of years. Monocultures unbalance the soils nutrients and in the worse case make it infertile. This is because one plant species needs certain nutrients in the soil and doesn't need others. That way, all of the nutrient that it needs is used up and there is too much of other nutrients. This can cause the soil to become infertile, meaning that almost nothing can actually grow there. One technique to avoid this is to rotate the crops every year and also have each field have one year where it isn't used at all and can recover. One more point is that the more biodiverse an area is, the more CO2 is stores. Tropical rainforests with high biodiversity can store more CO2 than a palm oil plantation with just the same plant species for as far the eye can see.

So how do we move forward? What is science doing about this problem? The good news is that this problem is now recieving the attention it deserves. It's even a boundary in the planetary boundary model which we explained a little while ago. One exciting concept is using AI. AI can be an amazing tool for science. Now scientists are using it to measure biodiversity from listening to recordings of animal sounds. Some areas are hard to explore because of thick undergrowth or the animals are very secretive. So simply leaving recording devices in the area and then getting AI to recognise the different sounds is very effective. The sustainabile development goals are very important targets. Unfortunately we are quite far behind on the goals regarding biodiversity and marine life. Another idea that's being considered is calculating biodiversiy loss into prices. The same way that sometimes CO2 emmissions are included in prices, the same could be done in regards to biodiversity. Scientistss from all over the globe are now collaborating and sharing data and technology in global monitoring systems for biodiversity. This also means including other scientists not just biologists and ecologists in the dicussion. Integrating the knowledge from different areas, like biodiversity, climate change, economics, politics, sociology and virology, really accelerates the progress made it each of these areas. All of the topics are different, but they all happen in the same system, our planet.

We hope you enjoyed this post. See you next week!

Animals 21-25 in our '50 incredible animals' series

Hi Everyone! Here are the next five animals in our current series! We hope you learn something from this. 21. Stick insect Stick insects are masters of disguise. They look like twigs or leaves. This strange appearance makes them hard to spot when stationary. Stick insects are herbivores, feeding on leaves, and can live for up to three years. Their habitat includes most tropical and subtropical regions, but there are a few species that live in temperate areas as well. There are roughly 3 000 different stick insect species! Not much more is known about them, because they are difficult to find. The two main threats to their populations are the pet trade and people killing them so as to frame their carcasses, like butterflies. Their conservation status ranges from critically endangered to least concern - so basically every category that is on the list! 22. Glass frog The glass frog is, well, see through. You can literally ...

Deforestation and why it’s a problem

Hi everyone, Welcome back to another post. Today we’ll be talking about deforestation and its impacts on our earth. Deforestation, the widespread clearance of natural forests, has been happening for thousands of years. One example is Western Europe, where, two millennia ago, 80% of the land was cloaked in dense forest cover. However, over time, a significant portion of this green expanse was sacrificed to create room for crops, livestock grazing, and as a source of fuel and building materials. Presently, a mere 34% of Western Europe retains its woodland. Today, the tropics deal with the brunt of deforestation. Activities such as mining, agriculture, road construction, and the establishment of vast cattle ranches drive the mass clearance of tropical rainforests. This results in the release of huge amounts of carbon dioxide into the atmosphere, exacerbating the global climate crisis. The consequences come in two waves: first, the reduced number of...

Photo Essay | dolphin spotting boat ride

Hi Everyone! Quite a while ago now, me and my family went on a dolphin spotting boat ride, and I've been meaning to share some photos for ages now! We saw so many dolphins very close up and we managed to get some good shots, although it can never be as magical as in person! All photos in this post were taken by me or my family. They were so close to the boat! This photo is stunning! It's under the water! Again - under the water! It was so hard to capture them jumping! This was the boat.... ...

Our 50th post! - and animals 1-5 in the '50 incredible animals' series

Hello Everyone, Today is a special post - to celebrate our 50th post we are starting a new series. This series is about 50 incredible animals. We can't promise that you haven't heard of any of them, but we have tried our best to find some of the most rare and in some cases bizarre animals possible. We can't fit 50 animals into one post so we have split them out over 10 posts. We'll try and publish at least one post every one or two weeks, but you know that we're not very good at keeping to the schedule! So the first five animals that you will (hopefully) find incredible: 1. Dumbo octopus They are the deepest living of all octopus species and are able to pounce on their prey and eat it whole. Their diet includes snails and other creatures they 'hoover up from the ocean floor'. They are called Dumbo elephants as a nod to Disney's elephant because they have fins that resemble the elephants infamous big ears! The...

Animals 11-15 in our '50 incredible animals' series

Hello, We have another five amazing animals for you today. Enjoy! 11. Dhole This is a dog species which looks rather like a red fox . They are difficult to put into any of the dog subfamilies. They aren't foxes, nor wolves, nor domestic dogs. Dholes are fast runners and live in packs of 5-12 individuals. Although sometimes, different packs will join forces to become a pack of 30 or more individuals! However, these super packs are broken up after a successful hunt. The different packs rarely attack each other as neighbouring packs are often closely related. Dhole packs live in burrows with multiple entrances. They can be found in eastern and southern Asia. They eat wild berries, insects and lizards and as a pack hunt deer, rodents and other wild mammals. Interestingly, unlike other dogs, they rarely kill by biting at the throat. They are also good swimmers! 12. Irrawaddy dolphin The Irrawaddy dolphin can be found in coastal areas of south a...

Photo Essay || Iceland Series (part 1)

Hi Everyone! I recently went on a school trip to Iceland! It was such an incredible experience (and I'm going to sound cheesy now) but it was also incredible to do it with some of my closest friends! I saw so many incredible things and learnt so much, so I couldn't resist sharing a little Iceland mini series of posts, all about Iceland, both my experiences there and what I saw, but also the way it uses geothermal energy, and the animals, natural landforms and plants that are there. Today I'm sharing some photos of my trip. These are all photos I have taken, and are also the highlights so please bear that in mind as you browse these! I hope it is interesting and inspires you to book a trip to Iceland! The blue lagoon <33 landscapes.... Lost little farmhouses a...

Palm Oil

Hi everyone, Today we would like to share with you some information about palm oil. With all the focus on climate change and plastic pollution, not many people are acting against the use of palm oil. Workers First of all, the managers promise that the workers will have good money, but when they arrive, their passports are taken from them, therefore, meaning they are trapped. Soon they find out that they aren't paid as well as promised. They have to work long hours with no breaks, maternity leave or sick days. Some people have to spray pesticides with leaking cans and no safety gear, meaning they become ill but are still forced to work. Deforestation Many animals are losing their home because the trees are chopped down to make room for the palm trees. they are now facing extinction. Also, trees helped to slow down climate change, but without them, climate change speeds up. So this is a big problem. Help your planet! Image:...

04.10.2020 Animal of The Week: Orca

Hello everyone. This week's animal of the week is Orca. They are also known as killer whales. Habitat Orcas live all over the world. They migrate according to where their prey are. However they are more common in colder waters. Diet Orcas are at the top of the food chain and have very diverse diets, eating mainly fish but also penguins, and marine mammals such as seals, and even other whales. They hunt (and live) in groups, making them very dangerous to certain species. Dangers There are a few dangers that they face, although for now the population doesn't seem to be suffereing. Some of these are: -Hunting for entertainment as they are intelligent creatures and so appeal to people who want to test their skills. -Polluted waters can be a threat as when certain chemicals get into the orca, most likely from their prey, they can be lethal. These can get into the water by oil leaks and chemical leeches. -Prey as overfish...

September Top Tips | recycling

Hi everyone, Today we are going to be talking about recycling. Recycling is quite big thing in the media, with some critics saying that it doesn't help. But I would say that even though it isn't going to save the world, it will make a small difference and probably save you some money! So here are some recycling ideas (although depending on your personal situation it might be up cycling or down cycling): An old t-shirt turned into an apron An old t-shirt turned into a cushion Tin cans turned into plant pots Tin cans turned into pencil holders Plastic bottles or clear plastic tubes turned into bird feeders An old handbag turned into a picnic basket Lotion, shampoo and conditions bottles turned into storage A shoebox turned into a make up organiser Old t-shirts turned into a baby blanket Plastic spoons turned into mirror decorations Bike parts into a lamp shade An old piano turned ...

The life of ... a kangaroo

Welcome back to Green World, Today we're talking about a rather amazing animal that we've all heard of: the kangaroo. Kangaroos are marsupials. They have powerful back legs, short front legs and a strong tail for balance. Kangaroos can weigh up to 90kg and stand over 1.80m tall. They are probably best known for leaping about on their hind legs. And for good reason, grey kangaroos can cover 9 meters in a single bound and travel at more than 55km/h. Interestingly, red kangaroos use less energy when traveling at 10km/h than when traveling at 6.5km/h. All Kangaroos live in Australia, but different species inhabit different areas. Eastern grey kangaroos are found in eastern Australia and Tasmania. Western grey kangaroos are located on the southern coast and in the southwest of western Australia. Red kangaroos dwelll in the interior grasslands and desert while antilope kangaroos can be found on the plains of the tropical north. They l...
