10 animals on the edge of extinction you didn't know about no.4 - Sumatran elephant

Hello everyone,

This is the 4th post in our '10 animals on the edge of extinction you didn't know about'. Today we are going to be talking about Sumatran elephants. You've probably all heard about Sumatran tigers, which are also on the edge of extinction, but Sumatran elephants are much less well-known.

Characteristics

Sumatran elephants live for around 70 years and grow 2 - 3.2m tall. They weigh 2 000 to 4 000 kg and are the smallest subspecies of Asian Elephant. The males have tusks, however, these don't grow as long as their African counterparts. The females also have tusks but these are normally so small, that they are hidden under the upper lip. Sumatran elephants are herbivores, eating bark, bananas, young fresh leaves and occasionally various wild herbs.

Social lives

Elephants are very social and live in herds of 20 - 35 individuals. These herds are led by a dominant female. Males leave when reach adolescence, either willingly or forcefully. Adult males are solitary, while adult females will stay in the herd. Elephants will breed at any time of the year but the peak season is during the rainy season. Pregnancy will last 19 - 21 months, that's more than double that of humans! This means that one female can only give birth once in 4 years, meaning that the population takes a long time to grow. A newborn calf will weigh less than 90 kg!

Population & Habitat

Sumatran elephants only live on Sumatra Island (in Indonesia). They live in forests and have a current population of 2 400 to 2 800 individuals. Their population is fragmented over different areas of the island and decreasing. In just the last 25 years, half of the population has been lost and they now only live in 69% of their original habitat. And over the last three generations (about 75 years) they have had an 80% population decline.

Human interference

Deforestation is the main reason for habitat loss. As farmland and human settlements expand into elephant territory, conflicts between farmers and elephants become more common. Most of these conflicts leave the elephants dead. They are also hunted for ivory, which has a very high commercial value. Due to all of these factors, in 2011 the IUCN changed their endangered status from endangered to critically endangered.

Next year, we will be discontinuing the Top Tips series. It has been a cool series to write but now it's time for something new. Here's the vote so that you can decide what we do next year!

Discussion || Should Everyone Switch To Electric Cars?

Hi Everyone! Thank you so much for joining me today, as I hop on the blog to discuss whether everyone switching to electric cars would really help the environment. In other words, should everyone switch to electric cars? This is the first part of a two-part series, discussing electric cars, so stay tuned for part two!! I would like to start this post by stating that I am by no means an expert. This is knowledge I have from my own experience, and from research I have done. If anything is incorrect please take it as it is and accept that this is a discussion and I am taking on board all opinions from reliable sources on this complex topic. Electric cars are a huge topic when it comes to sustainability and "saving our planet". There is no debating the fact that electric cars are better for the environment than diesel or petrol once they are on the road. But the production of them is often very polluting, with one study show...

Ozone layer

Hi everyone, What even is ozone? And the ozone layer? Where does the hole in the ozone layer come from and what does it mean? Is it dangerous? What can be done? Often the ozone-talk can be complicated and confusing, keeping an overview is hard and understanding all the problems always difficult. Let us break it down a bit for you: What is the ozone layer? We'll start with the basics: The ozone layer is part of the stratosphere, which is the second layer of the Earth's atmosphere, between 10 and 50 km above the Earth's surface and made up of protective gases. One of these protective gases is ozone. There is not much ozone in the atmosphere, only 0.3 molecule of ozone per 1 million molecules of air. This is because ozone is chemically unstable and only forms when ultra violet radiation (UV light) hits oxygen and breaks the bonds between the atoms. It fact it is so unstable that even when it has formed, it breaks down again relatively quickly. This leads to ozone turning back ...

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 ...

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...

April Top Tips: ten tips for environmentally friendly travel

Hi Everyone! We haven't been very present on the blog again recently but we are back today with ten top tips for environmentally friendly travel. Most forms of travel over long distances (unless you are willing to put in a lot of physical effort) use fossil fuels and are generally not good for our planet. So today we will be giving you a few tips which although won't mean that your travel is 100% planet friendly, will be a good start to doing as much as you can. Your Green World Blog Team💚 1. Use trains and boats rather than planes where possible Planes are awful for the environment. They are, however, extremely practical and so easy to use, cheap...It's hard to avoid them! They are so quick too so you don't have to spend as much time travelling. However, they are really bad for the environment. For example, you could fly once to Edinburgh from Heathrow for the same carbon dioxide levels as driving to Edinburgh 336 times! 2. Fly...

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.... ...

4 tips for eco-eating

Hi everyone, Today we are going to be sharing some tips for making sure that what you are eating is environmentally friendly. 1. Check for Palm Oil As you can probably tell from past posts, we are strongly against using palm oil . Palm oil is often used in food products, so by quickly glancing over the ingredients list on the product's packaging, you can make sure that no rainforest has been cut down to make it. For instance, we would recommend buying "McVites Digestive light" instead of the classic version as it was specifically designed to not contain palm oil. 2. Shop Locally The shops in your local area will probably get their produce from local sources, so by buying your food from them will ensure that no CO2 has been produced from shipping, as well as supporting the local community. Some shops have recently started to serve dry ingredients (such as flour and sugar) in paper bags or in your own containers, which leads onto... ...

Hello Everyone, Welcome to this week's animal of the week post. This time about the ladybird, and personally I can't wait to find out more about these creatures. Enjoy! Which ladybird we are investigating today? Today, I am telling you about the seven-spotted ladybird (Coccinella septempunctata), which is the most common ladybird in Europe. Other species include the Two Spot Ladybird and other uncommon ladybirds such as the 16 Spot and other peculiar types. Habitat The seven-spotted ladybird lives in a variety of habitats such as meadows, gardens and hedgerows. They can also be found on farmland, especially with crops such as alfalfa, clover and wheat and corn before it grows too tall. Diet The seven-spotted ladybird feeds on a range of aphid species. This is why they are often referred to as a gardener's best friend as they eat these creatures who can damage plants. They can also eat white flies and anything else that is soft-bo...

19.07.2020: Animal of the week: Honey Bees

Hi everyone, This week's animal is the honey bee. Enjoy! General Information An average honeybee hive is made up of one queen, hundreds of male drones and thousands of female workers. If the queen bee dies then a new queen is created. The workers select a young larva and feed it with a special food called ‘royal jelly’. The ‘royal jelly’ makes the larva grow into a fertile queen. Queens live for several years but the workers only live for five or six weeks. An average worker will make a twelfth of a tee spoon of honey during her entire life. Drones are turned out of the hive and left to die in Autumn. In the summer months, the queen bee is very busy, she can lay up to 2500 eggs in a single day. How they affect the world around them Honey bees are very important for flowers, fruit and vegetables. This comes from the fact that they are pollinators. They help the plants by transferring pollen between male and female parts, meaning the plants can g...

Eco Bricks -Taking Upcycling to another level

Eco Bricks Are they the key to the world's plastic pollution problem? Or at least a helpful factor if they became a permanent solution with no disadvantages? But what are they anyway? How are they useful? And how can individuals help every day? Here are some tips for everyone wanting to save plastic and help the earth. Eco bricks are plastic bottles, filled densely with hard and soft plastic that make a bottle so hard and sturdy that they could be used to build houses. Which in fact, they are. To make an Eco-Brick, you need a clean and dry plastic bottle, a long stick and lots of plastic. All plastic must be clean and dry, so it should be washed and dried or hung up to dry before usage. Now the bottle can be filled with layers of soft and hard plastic alternately that is pushed down with the stick to fill every corner of the bottle. That is done until the Eco-Brick is entirely stuffed with plastic and hard as a brick. The advan...
