10 animals on the edge of extinction you didn't know about no.3- The Monarch butterfly

The monarch butterfly is an animal you will probably have seen around in your life. It's not the kind of animal you will know the name of, much less the extinction status, but the monarch butterfly is rated "endangered" on the WWF website. It's affected by climate change and humans and its numbers have declined greatly.

Fast Facts

The Monarch Butterfly is a rather small animal, however pretty large for one of its species. Their wingspan ranges from about 90 to 100 mm, the male butterflies being slightly larger than the female. They are orange with a black patterning and white dots on the sides of their wings, the vibrant colours warn predators of their bad taste. Monarch butterflies are known for their migration habits. They are mainly found in northern America, but travel to the south (Mexico or California mainly) to hibernate. These tiny butterflies travel almost 3 thousand kilometres and can be found all over the planet by now. They have adapted with shape and size to live all over the planet! Monarch butterflies usually only live a few weeks, except for those who travel south. Those live for up to 9 months! This results in roughly 4 generations of monarch butterflies a year.
Monarch butterflies lay their eggs on milkweed plants. The caterpillars can be recognized by their vertical stripes of black, white and yellow-green.

Endangerment

Of course, there are more than just a couple of factors to the decline of monarch butterflies, but climate change, deforestation and fewer milkweed plants to lay eggs on are the main problems. We all are aware that climate change alters the general weather and climate of our planet and that that in return affects animals and plants in many ways. The monarch butterfly is very sensitive to that, as different temperatures in its breeding grounds would affect its migration route colder winters would kill the butterflies.

Additionally, the monarch butterfly (like so many animals) is affected by deforestation. It hibernates in the mountain forests in Mexico for example where humans are also active in tourism and agriculture. Pesticides are used in agriculture but also decrease the number of milkweed plants available for the butterflies to lay eggs on, which makes reproducing difficult.

We hope you enjoyed this!

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...

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...

Animals 36-40 in our '50 incredible animals' series

Hi, As you probably noticed, we took a break from this series, mostly due to having just too much to do. But we're back now with the last three posts. 36. The Pinocchio frog The Pinocchio frog can be found in the Foja Mountains in Indonesia. They mainly eat insects, although little is known about them. They are named because the males have a spike on their noses. They were only discovered in 2008, and this was completely by accident! It remained unnamed scientifically until over ten years later when it was given the name " Litoria pinocchio " . There is very little information about them but Wikipedia states that "the male Pinocchio frog inflates its nose when calling, and the nose decreases in size when the frog is calm and quiet," which I think is hilarious and so interesting! 37. Snub-nosed monkey Especially noticeable due to their curious looks, the snub-nosed monkeys can be found in the forests of central China and northern...

Green Pets: Introducing my new house plant!

Hi Everyone! As you can tell by the title of this post, I got a new houseplant! It was a Christmas present but I chose it in a really sweet plant shop near me. It is called a Mind Your Own Business, in more technical terms a Soleirolia. It's latin name is Soleirolia soleirolii. Introducing Mr Darcy! I named it Mr Darcy because I love Pride and Prejudice and I thought it appropriate! It needs to have constantly moist soil and has to be watered by being put in a bowl of water, rather than with a jug. This is because it will get a hole where the water has gone down as it is quite delicate and the leaves are very fine. It's important to look up how much water your house plant needs and get tips from experts to help your plant to thrive. I talked to the lady in the shop when we were buying it and she told me about how to look after it. It is joining my two other house pla...

We could keep the fact file too and there is an option for that so,...

29.11.2020 Animal Of The Week: Jaguar

Hello, Today (29th November) is world Jaguar day so this week our animal is the Jaguar. The Jaguar is an animal I know pretty much nothing about so I am going to learn a lot too! Jaguars (panthera onca) live for 12 - 15 years. Their heads and bodies are 150-180cm long and their tails are 70-90cm long! They weigh 45 - 110 kg. Habitat Jaguars live primarily in the Amazon Basin, though they can be found in smaller numbers in Central America. They once lived everywhere from central Argentina up to the southwestern United States but since the 1880s they have lost over half of their territory. They are mainly found in tropical rainforests but can live in savannas and grasslands. Diet They eat fish and turtles as they are actually quite competent swimmers as well as deer, iguanas, birds and monkeys; they will eat almost anything! Are they endangered? Jaguars are classed as near endangered and face several threats. South and Central Americ...

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 ...

Rachel Carson 1907-1964

Hi everybody, Today I am going to tell you about a really inspirational environmentalist. Her name is Rachel Carson. I hope her story inspires you to be more careful about pesticides. As a girl, Rachel adored writing stories about animals. She got a degree in zoology but had to go home to care for her ageing mother. She wrote a series of radio shows about fish for a living. Rachel's program, called 'Romance Under Waters', was a big hit. Her ways of writing were different to anyone else and no one had made that sound so interesting before. It proved that she was talented in not only science but also writing. She wrote two books called 'The Sea Around Us' and 'The Edge Of The Sea'. When Rachel moved to the countryside, she realized the impact of pesticides. At that time farmers sprayed chemicals on their fields a lot to protect them from animals that may want to eat them. Rachel worked out that they were killing pla...
