Endangered species conservation - how scientists bring back species from the edge of extinction

Hi everyone,

We always talk about endangered species and how we really need to help them. But we never really say how we can help them. I mean of course, stop climate change, remove the plastic pollution from the ocean, ban hunting, but those are massive tasks and not easy or quick to do. So how do scientists stop species from going extinct? With nearly 40 000 species threatened, there is no one solution for all species.

Habitat conservation and official protection

One of the most basic and yet often really effective form of conserving and restoring populations is to protect and conserve their habitats. This often includes legal bodies forbidding deforestation or mining. Many habitats have been made into national parks or other protected areas and in some places, visitors are strictly prohibated. In other places, voluteers are working day and night to clear plastic on beachs and in rivers. Bans on hunting and poaching have been effective in many speices such as sea otters, whose incredible fur lead to excessive hunting until an international ban on hunting, which pushed sea otter populations back up. Another common example of legal protections is whales. They were hunted close to extinction until protected by the International Whaling Commission. Although there are still countries that refuse to ban whaling, whale populations have been slowly making their comeback.

Captive breeding and artificial insemination

Now we start to move into methods that have a lot of critism. Don't get me wrong, banning hunting and whaling met a lot of opposition, but probably not as widespread as our next method. Lots of people don't like zoos, I get that, I don't particulary like looking at big cats pacing inside small inclosures or polar bears desperately trying to find shade in an ice free enclosure in the middle of hot summer. But lots of zoos do important conservation work. Sometimes, it isn't possible to protect an animal in its natural habitat. Lots of governments don't want to or can't ban hunting and it often continues illegally anyway. Many zoos have breeding programms to help with exactly those problems. They breed animals in the zoo and wait until the young have matured before sending them back to their natural habitat to boost the local population. This isn't without problems, animals can find transportation from zoos to wilderniss very stressful especially if it means long distance travel. There are also problems with the animals not being able to survive in the wild because of not being used to predators or different food to what they had in the zoo. Not to mention the fact that this still doesn't make their time in the zoo any better. Some animals like pandas don't always mate even when given the chance. Here zoos often resort to artificial insemination. Again this is met with the critism that these procedures aren't comfortable for the animals and are sometimes unnecessary.

Relocating species to a new habitat

The last point I want to talk about today, is possibly the most controversial. The idea of relocating species to a different habitat is constantly argued about among scientific circles. Many biologists and ecologists say that it's a bad idea, others say that it's necessary to stop these species from dying out. The main idea is that if a habitat becomes uninhabitable, for example it dries out due to climate change, researchers look for another area that the homeless animals might thrive in. Another name for this is assisted migration. This is currently being trialed in western swamp turtoises in Australia. Their habitat is drying out because of reduced rainfall. So a team has attempted to rehome them. Critics warn of these relocated species becoming invasive species and uprooting the new ecosystem. Species can also often have a hard time adapting to new environments due to different climates, landscapes, food options and predators, similar to how animals bred in capativity struggle when reintroduced to their actual habitat.


There are obviously more options that scientists are looking into, but these are a couple of them. We hope you enjoyed this post. Let us know what you think about these methods in the comments!

Ecosia

We all need to do something to save our planet: it is no use just leaving it to Greta Thunberg! She is very inspirational, yes, but she can only do so much. She isn't superhuman! The climate crisis is up to us; up to you. We all have to get stuck in. Research, learn, discover and most importantly: never give up! The world's animals need us. The world's trees need us and a simple way to do this is to switch to Ecosia. Ecosia is a search engine but it plants trees while you search the web. Okay, it doesn't have as many websites as google so you may want to have google as a backup but it plants trees: this is your opportunity to make a simple change. Just google Ecosia and search to plant trees. Make a difference. Image: This image  is owned by  Binyamin Mellish on  pexels.com .

How has the COVID-19 pandemic affected the environment?

Hello and welcome back to another post! The pandemic has affected us all in many ways but what about the environment. How has it been affected? Today we'll be going into that. How did it start? So COVID-19 broke out in late 2019 in China but how it started is still a greatly controversial topic. Prof Stephan Turner told  The Guardian in an online article in April: [...] says what’s most likely is that virus originated in bats. However, how it transferred to humans still isn't 100% certain. Scientists mostly agree that it didn't come directly from a bat, but instead was transferred through another animal. Regardless of how it reached humans, the main idea is that it came from a live animal, either in a food market or in the meat industry . Either way, it was our mistreatment of animals that lead to this disastrous pandemic that has claimed the lives of over 6.5 million people! Emissions When many businesses, industries and...

16.08.2020 Animal of the week: Elephant

Hello. On the 12th of August it was International Elephant Day, so we decided that this week's post should be about elephants. Elephants are the largest living land mammals. There are three types of elephant; the African bush elephant; the African forest elephant and the Asian elephant. African elephants have larger ears, whereas Asian elephants have smaller ears. Elephants use their trunks to breath, bring food and drink to their mouths and to grasp objects. Elephants' legs are like pillars. They carry the Elephant's massive weight. African bush elephants weigh 6000kg, Asian elephants weigh 4000kg and African forest elephants weigh 2700kg. Basically, they are very heavy.Elephants eat grasses, small plants, bushes, fruit, twigs, tree bark, and roots. Elephants can live up to 70 years old in the wild. They communicate by sight, touch and smell. Sadly, these wonderful mammals are in danger. African elephants are listed as vulne...

Linking climate change and inequality - 'The Great Carbon Divide'

Hey everyone, Have you heard of 'The great carbon divide‘? It is often referred to as the 'carbon footprint gap' or the 'emissions imbalance‘, and produces frightening numbers. The great carbon divide describes the huge gap between the amount of carbon dioxide the rich versus the poor emit, and these numbers shocked even us.  What does this mean?  There have been many different studies, and all of them show terrifying results. One study from the Guardian and Oxfam, reports that the richest 1% of the world's population emit more carbon than the poorest 66%. The richest 1% consist of 77 million people, which may seem like a lot at first, but the poorest 66% refers to over 5 billion people! Africa, which is home to 17% of the world's population, only causes 4% of the world's emissions. This top 1% emitted 16% of global CO2 emissions in 2019, that's 5.9 billion tonnes of CO2. Modelling suggests that it would take someone who isn't in the top 1% about 150...

LGBTQ+ animals | Pride month special 2022

Hi, As you probably know, it's pride month! Here on Green World we fully support the LGBTQ+ community. Many homophobes and transphobes will tell you that being LGBTQ+ isn't natural. But what they don't know is that over 1 500 different animal species are indeed part of this community! So, today we are going to being covering just a few of these animals. Note: We do not tolerate LGBTQ-phobic comments. All hate comments will be deleted. Sexual Orientation Within the LGBTQ+ community, there are many sexual orientations and most of them can also be found in animals! Here are just a few examples: Rams You probably didn't know, but up to 8% of rams are homosexual. This is quite a lot considering that only 1.7% of US adults identify as homosexual. Laysan albatross 31% of all pairs were lesbian in one study. That is a lot. Bottlenose dolphins One gay pair had a 17 year long relationship. This goes to show that same sex pai...

Ways to help make your household environmentally friendly

We have told you a bit about the problems that the environment is facing in previous posts but we haven’t told you how to help the environment around the house. You don’t even need a garden to make a difference! Ways to help stop global warming Tip 1: Turn the lights off when you leave a room. Tip 2: Walk or cycle on short journeys. Tip 3:  Don’t have the windows open and the heaters on at the same time. Tip 4: Never leave your engine running Tip 5: If you can, buy an electric car as these produce less Co2.   Ways to help stop plastic pollution  Tip 1: Buy a water bottle. It seems simple but every year the UK uses an estimated 13 billion plastic bottles. Tip 2: Use a bar of soap and a bar of shampoo instead of shower gel and bottled shampoo. Some say soap can dry your skin out but if you do your research you can find plastic-free high-quality soap, perhaps at a price but it depends on where you get it from. Tip 3: Make...

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 ...

Animals 41 - 45 in our '50 incredible animals' series

Hi everyone, 41. Ghost shark So first of all, this is a real animal and not a horror movie! Ghost sharks, often referred to as chimaeras, include around 50 species. They mostly live in the deep ocean and are seldom seen, hence the name. They can be found all over the world. Some species have a large range, for example, the rabbit fish which inhabits the entire northern Atlantic Ocean, or a small range, like the Galapagos Ghost shark which only lives in the waters around the Galapagos . Not much is known considering their population status however they are currently not considered threatened. It is assumed that they reproduce in the same way as most sharks. Not much else is known about ghost sharks. They are as mysterious as their name suggests! 42. Sea pig Again, this is a real animal! But it is not in any way like a pig (I have no idea why they called it a sea pig ). It is a type of sea cucumber, that lives in the ocean depths. Their bodies are fille...

Pollination

Hello everyone, Today we're talking about pollination and its importance in the world's ecosystems.  First a bit of basic plant biology. To reproduce most plants do have a differentiation into male and female, but not in the same way that we see in mammals. Both male and female reproductive organs can be found on the same plant, although not in the same place. Male gametes are produced in the stamens and are then found in pollen. On the other hand, female reproductive organs are called pistils and egg cells are found in the ovule (normally in the flower heads). Pollination describes the process of transporting the pollen to the egg cells, making it an essential part of the reproduction of plants. Nearly all seed plants worldwide require pollination to reproduce. Cone bearing trees also need pollination.  Pollination is almost always assisted by other organisms such as insects, birds and mammals to transport the pollen. In some species wind ...
