10 Animals on the edge of extinction, You did not know about no.1 - Yangtze Finless Porpoise

The first animal of this series is the Yangtze finless porpoise, a dolphin living in fresh water in southern China in the Yangtze river. It is one of the very few dolphins living in fresh water and the only species left in the Yangtze river. Unfortunately, the porpoise is facing extinction.

What is it?

The Yangtze finless porpoise is a dolphin species living in the Yangtze River in southern China. It is one of the very few dolphin species that live in freshwater, and the only one that survived in the Yangtze river after the Baiji Dolphin was declared functionally extinct in 2006. It characteristically is about 2 meters long, has no fins -as the name suggests- and no beak. Its mouth however is curved upwards like a smile, giving the Porpoise and cute and friendly face. It feeds on small fish, crustaceans and molluscs. Sadly, the Yangtze finless Porpoise is considered "critically endangered" as there are only about 1000 of them left. 

Why is it dying out?

The Yangtze finless porpoise is facing multiple dangers from all sides. All of them, unfortunately, are human-made, as we make the waters they live in extremely dangerous. The Yangtze river is their only natural habitat, making it too dangerous there for the Porpoise, which is basically directly killing them. The river is a major travelling and fishing as well as trading route and therefore full of boats at all times.

 Often Porpoises get injured or even killed by boats or their gear, especially fishing gear. Like so many other marine animals, Porpoises often get entangled in fishing nets and drown, as they can only hold their breath for up to 4 minutes. But even if they do not drown, the fishing itself is bad enough.

 Overfishing to be precise, as the Porpoise needs a big supply of food that we fish away with no second thought, resulting in a lack of food for the Porpoise. Additionally, we pollute the river so much with all the boats on the river and the plastic we throw away, that they really suffer from that. Experts believe that, if no major action is taken, the Porpoise will be passed within the next century.

How can I help?

I know all of that sounds like a situation that cannot be saved. However, we can definitely make an effort to improve all of these very serious issues. The main issues are overfishing, pollution and injuries due to boats or their gear. Again, this sounds like you as an individual cannot make a difference, especially if you do not live in China, but that is not true! Here are many different things you could do to support the porpoises:


1) Overfishing is generally an important topic to keep in the back of your head when buying fish to eat because there are many things you can keep an eye on to buy the environmentally friendliest fish you can. The first and most obvious choice to make is where you buy your fish. Is it the Organic market or the really cheap supermarket from next door? Other questions to ask yourself are: Where in the world was the fish caught? Has it been transported a long way, emitting lots and lots of CO2 and do you have access to local fish? How was it caught? 

This question might make little sense to some of you, but let me tell you this: really cheap fish is often caught with gigantic boats that drag massive nets behind them through the ocean, that not only catches the fish they want to catch, but also many other marine species that are often endangered. Or there are these farms underwater that breed the fish and then sell them. And obviously, the traditional way of fishing one fish at a time is the most sustainable. Especially if you fish them yourself. But many people do not have the opportunity to do so, so a good idea would be to look out for the MSC label. The MSC label is a label you can get on seafood in over 100 countries, certifying that the seafood you buy has been fished sustainably. You exactly what that means and what the standards are for the MSC sets, you can check them out on the website. I will link it below (1).

If you are interested in doing your part in stopping overfishing I would also take a look at the Sustainable Development Goals website, I will also link below (2). Both websites have information and tips from experts on the topic and are really detailed and interesting. 


2) Pollution. We all are aware of this problem, it really isn't new. What can I say, apart from the stuff you hear all the time? Reduce materials such as plastic and paper/cardboard in daily life as much as you can, plant Vegetation wherever you are, and reduce, reuse, recycle and upcycle as much as you can. Save energy, and use the car as little as possible...I believe we also have an article on being sustainable in daily life. If not, I will write one soon. Try not to travel so much, though I am probably really not the right person to ask something like that.


3) Injuries due to boats of their gear. That topic is rather hard because there really isn't that much you can do when you are not there. But when you are there, think of the Porpoise, and avoid a boat tour if you can. The most important and efficient thing is always: If you can do nothing else, share the information with people! It seems like a small thing to do, but the more people know, the better!

The life of ... an alcon blue butterfly

Hi everyone, Today we are going to be looking into the life of an alcon blue butterfly (Phengaris alcon). After mating, the females lay their eggs on marsh gentian, a blue-coloured wildflower. The eggs can only be laid on these flowers, as this is what the newly hatched caterpillars will eat. Although in some alp regions, they can also be found on willow gentians, a close relative of the marsh gentian. Once the caterpillars have hatched from the eggs, their main predator and danger are the ants that swarm below. But high on their plant homes, the caterpillars are safe. However, this isn't where the alcon blue caterpillars are going to stay forever. Eventually, they drop down to the ground using silk strings. With no protection, they are soon dragged off by the ants. The most amazing part is, the alcon blue caterpillars give off the same scent and chemicals as the ant larvae. So the ants take the caterpillars back to their brood chamber, wher...

The life of ... a koala

Hello everyone, Today we're talking about koalas. Also known as koala bears, koalas are marsupials. So they're actually not bears. Koalas, phascolarctos cinereus , are tree dwelling and probably best known for spending most of the day sleeping. They live for up to 15 years in the wild although captive koalas generally live for longer. Koalas have a stout, gray body and a cream-coloured chest. They have a broad face, small yellow eyes and big fluffy ears. In adaptation to climbing, their feet are strong and clawed. Adult individuals in South Australia weigh 14kg and are 60-84cm big. Their Eastern cousins are considerably smaller. Koalas are found in Eastern and Southern Australia, where they live in eucalyptus trees. They feed on the leaves of these eucalyptus trees, eating up to 1.3kg a day. With a body weight of up to 14kg, this means they eat just under 10% of their body weight every single day. However, the le...

Eco system Galápagos: Part 1 Geography

Hello and welcome to the first post about the Galapagos Islands. Currents and Winds The volcanic islands of Galápagos started to form 4 million years ago. Where they lie, is unique. They are situated directly on the equator, on the Nazca tectonic plate. The Galapagos Islands are on the crossroads of three currents. The cold South Equatorial Current flows westward towards Galapagos. The warm Panama Current runs in from the north. And finally, the deep sea Cromwell Current runs from the west. The Galapagos Islands are also where the Northeast Trade Wind meets the Southeast Trade Wind. Galapagos Hotspot 21 Volcanoes make up the Galápagos Islands with 13 still active. The reason for this volcanic activity is a giant hotspot under the island. A hotspot is a gigantic column of super heated molten lava, rising up towards the surface. It is immense; at least sixty miles (97 kilometers) across and 1800 miles (2897 kilometers) deep. It connects the islands to ...

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...

02.08.2020 Animal of the week: Owl

Hi everyone, This week's blog post is all about owls. Habitat There are many different types of owl: barn owls, long-eared owls, snowy owls and lots more. Different species live in different places. Here are a few examples. Snowy owls live in the Arctic . Great grey owls live in pine forests. Elf owls live in deserts. There are about 130 different species of owl. Owls can be found everywhere in the world apart from Antarctica . Owls live in trees, holes in the ground, barns and caves. Most owls do not migrate in winter. Diet Owls eat insects, spiders, fish, reptiles, amphibians, birds and small mammals. What they eat the most depends on the type of owl and where it lives. Screech owls feed mostly on insects. Barn owls mainly eat mice, shrews and voles. Eagle owls eat hares and young foxes. Some owls can even fish like the Asian Fish Owl. Even though some species prefer a certain type of food, most owls will eat whatever they can find...

July Top Tips | 3 up-cycling ideas

Hi Everyone! For July, we will be sharing 3 up-cycling ideas that you can easily try at home to save money, and the planet at the same time! Thank you so much for joining us today and let's get into it! 1. Fabric off cuts to gift wrap! So you've just finished making a new cushion for your lounge or sewing a bag, and you have fabric left over. These small pieces of fabric still may have a purpose one day, so you fold them up neatly and place them in a drawer, just in case. But the time never comes and the same offcuts have been in the drawer for years. Why don't you use it as gift wrap? Wrapping paper is a problem environmentally so using fabric is a win-win! And it can look fantastic! If your offcuts are too small, why don't you sew them together and make a patchwork-style version? And the best thing is that it can be reused again and again! 2. Jars There are so many things that you can do with jars. Probably one of the ...

Amazon Rainforest series - part 3: human involvement

Hi everyone, This is the last post in the amazon rainforest mini series. It's all about how humans have affected the amazon rainforest. Unfortunately, most human impact on the amazon is negative. The Amazon rainforest faces many threats, but the main one is fire. You may think that the fires in the amazon are wildfires or created by accident, but that is not true. All over the amazon, farmers are setting fire to the trees and foliage. For only one reason, to clear land for farming. But this is a disaster. Last month, the amazon rainforest reached its tipping point . Due to the fires, it is now releasing more CO2 than it is absorbing. To feed our growing population, we are killing countless species. Species, that in some cases, we haven't even discovered yet. If the amazon rainforest goes, climate change will become pretty much unstoppable. But it isn't only animals and plants that are suffering. Do you remember all those tribe...
