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...

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...

Greta Thunberg's Speech at the UN Climate Action Summit 2019

Hi Everyone! I thought I would share the transcript of Greta Thunberg's inspiring speech from the UN Climate Action Summit. The phrase we remember is 'How dare you!'. But what did she really want us to take away from it? She wanted us to act, so watch the video using the link below and take action because the world isn't just going to heal itself. Greta Thunberg's speech at the UN Climate Action Summit video "My message is that we'll be watching you. This is all wrong. I shouldn't be up here. I should be back in school on the other side of the ocean. Yet you all come to us young people for hope. How dare you! You have stolen my dreams and my childhood with your empty words. And yet I'm one of the lucky ones. People are suffering. People are dying. Entire ecosystems are collapsing. We are in the beginning of a mass extinction, and all you can talk about is money and fairy tales of eternal economic g...

Maldives - the direct impacts of climate change

Welcome back, Today we’re looking at the direct impacts of the climate crisis . The main reason why people don’t believe in climate change is that they can’t see it with their own eyes. So, we’re going to have a look at the Maldives where the effects of climate change become more obvious with every passing year. Maldives The full name of the Maldives is The Republic of the Maldives. It is an independent country made up of about 1 200 islands in the North Indian Ocean. The northernmost island is situated 370 miles away from the mainland (India). The islands are actually the tips of an ancient volcanic mountain range that is now almost completely submerged. In fact, the highest point is 1.8m-2.4m above sea level with the average elevation being 1m above sea level. The islands have a large tourism industry, due to the stunning nature found on and around the islands. 500 000 - 1 500 000 tourists visit the islands each year. This is mainly 'nature to...

Autumn Leaves: The science behind one of the most beautiful seasons

Hi everyone! We know that at the time this post is being published it will still be August, and the height of summer here in the Northern Hemisphere, but within the next two months or so, autumn will well and truly be upon us. So, today, we thought we could talk a bit about the science behind this beautiful season. Thinking of autumn automatically brings to mind images of crisp mornings, cosy evenings, and of the picturesque falling leaves with their hues of red, orange, yellow and gold. The change of colour of these leaves marks a change of seasons, and the decreasing temperature and light levels that goes along with that. But why do these leaves lose their greenness and fall from the trees? Trees' leaves contain a chemical called chlorophyll which allows them to convert water and carbon dioxide into glucose, or sugars, through a process called photosynthesis . This is how they gain energy from sunlight. Chlorophyll is green in colour, ...

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...

Turning waste into valuables

Hi, So this post was requested on Twitter after our September Top Tips about recycling . Today we will be talking about how to turn complete waste into something reasonably valuable. This is basically a form of upcycling but to a more extreme level. 1. Ecobricks So, almost a year ago we did a post about ecobricks , but they are such a good example of turning waste into valuables that we decided to put it here anyway. Ecobricks are a building material made from plastic. The waste plastic is washed and then compacted into a clean plastic bottle (also waste). The bottle becomes very hard and durable. Multiple bottles can then be used as bricks and cemented together. The 'bricks' are strong and do not decompose. For more info, read our post where we go into more detail. 2. Metals Although this may seem like something not worth the time. When you separate the metals in waste (for example an old car), you can get usable metal out ...

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 willi...

How does plastic affect the environment?

Hello, I wanted to clarify exactly how plastic affects the environment. I hope this will explain. When plastic breaks, it releases toxic gasses that poison animals. Also, if plastic is swallowed it could cut or damage the inside of the animal. Many animals such as turtles and dolphins mistake the small plastic fragments for food. Even if the plastic is too small to cut into the insides of the animal or cause choking, too many micro plastics inside an animal will eventually block the digestive tracts and they will starve to death. Recent research proves that plastic has entered the human body. This is because plankton eats microplastics and small fish eat plankton. Bigger fish eat smaller fish and we eat the bigger fish. So inside us is plastic. Plastic also blocks waterways and sewers. This leads to the perfect breading grounds for disease carrying animals such as mosquitos. When plastic is burned it releases those toxic gas...

July 2021 Factfile - some news from the past month, animals and plants!

Hi Everyone, July is over and August is here. This month we've divided the 'News' section into 'Good news' and 'Bad news'. This will hopefully make the post more structured and easier to navigate. News Good news: Pandas classified as vulnerable Giants pandas are now classified as vulnerable according to Chinese officials. They were originally classed as endangered , but now that numbers in the wild have gone over 1 800 they have been reclassified. This is due to hard conservation work in China and funds from volunteers all over the globe. However, they are still vulnerable so it is important that the good work continues. For all those who have supported giant pandas through websites or those who work actively with them: keep up the good work! First baby beaver born on Exmoor in 400 years A baby beaver has been born on Exmoor, England, for the first time in 400 years! This is due to ...
