Zero-waste Challenge

Hi everyone, 

Welcome back to Green World for our first post of 2024! As explained in our wrap up post, this year the monthly series will switch between challenges and book reviews. We're starting with a challenge and this month we're challenging you to cut down on your waste!




1. No single use plastic bags challenge

Plastic bags are a disaster for the environment and they're not always even usable for us. Some of the really thin plastic bags will just rip as soon as you put something in them which is a nightmare if you're out shopping and need to transport your groceries home. When these plastic bags are then thrown away, they cause significant damage to our planet. Plastic bags often clog waterways and sewers which is a massive problem. Waterways, such as streams, and their ecosystems depend on moving water and if they get too blocked, the migration of different species is hindered. If a dam starts to form with all of the sticks, rocks and more plastic that is being transported down the river or stream, then the area can flood, causing damage to surrounding ecosystems. 

So what can you do? Our challenge for you this month is to replace the thin, breakable single use plastic bags with more environmentally friendly options. There are plenty of options here, reusable plastic bags are much stronger and can be used frequently for years without breaking. Paper bags are also an option if you don't have reusable ones (although the paper industry isn't that great either). For things like grocery shopping you could also take a cloth bag, tote bag or a rucksack. Especially if you're transporting heavier items then a rucksack might be a more comfortable option too - it's a win-win!

2. Plastic free kitchen challenge

We all know that plastic is bad for the environment, but lots of people don't think about it actually being bad for human health as well. And when we do think about that, we think about eating fish that has eaten and therefore contains plastic or about accidentally swallowing chewing gum (which is often made of plastic). But not so many people think about their kitchen. However, plastic in a kitchen can be really bad for you, as well as bad for the environment. 

The most common example is microwaves. Most people know that you shouldn't put plastic in a microwave and should take the food out of the packaging before heating it up. But why? Plastics release microplastics when they are heated up (and even when they're not heated up). If you microwave your food while it's in its plastic packaging, then your food will be full of microplastics. This problem is found everywhere in the kitchen, one article from The Guardian even explains how the glue that holds a tea bag together releases billions of microplastics into your drink.

With that in mind, it makes sense to minimise the plastic in your kitchen. It's hard to get rid of it completely, but that doesn't mean you shouldn't try. Things like using metal or wooden spoons instead of plastic ones, removing all packaging before heating your food up, wrapping food in beeswax wraps instead of cling foil or using a wooden chopping board are all realistic, reasonably easy steps you can take. 

3. No plastic bottles challenge

Again, microplastics. When you buy a bottle of water, you assume that it's had any potential health risks removed and is completely safe to drink. But in reality, the water gets contaminated by the plastic packaging that's supposed to keep it clean. The water is full of microplastics. These plastics may (research is still being done) be endocrine disruptors, which means that they disrupt our hormone levels. Some companies use a different type of plastic which contains BPA. BPA exposure has been shown to correlate and possibly cause cancer, heart problems, brain development problems and fertility issues. Luckily, this has been banned in certain countries.

So plastic bottles are definitely not particularly good for our health, as well as being a huge problem when they end up in the environment. But again, there are some alternatives. When travelling or otherwise away from home, bringing your own (metal) bottle is always a good solution. Lots of places now offer schemes and programs where you can refill your bottle for free. The Refill app is a great way to find places which refill your water bottle for free, so it's also cheaper than buying bottled water. If you're at home and your tap water is safe to drink, then there is no need for some fancy bottled water because chances are, it tastes the same or better (depending on where you live obviously). Radford University did an experiment where bottled some normal tap water and asked people to drink both the tap water and the bottled water and say which one they preferred (not knowing which one was which). Most people actually preferred the taste of the tap water!



We hope you will try some of these changes and complete the January challenges! Let us know in the comments which ones you're hoping to complete, we would love to hear from you. See you next week!

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 ...

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...

10 animals on the edge of extinction you didn't know about no. 9 - South Island takahē

Hello Today we’re talking about the South Island takahē, porphyrio hochstetteri . They are flightless birds, endemic to New Zealand. Takahē are brightly coloured and weigh 2.3-3.8 kg. They have red legs and a large red beak. Their feathers are coloured blue and green. They have wings, but these are only used during courtship or rivalry displays. They are territorial, with one family’s territory reaching anywhere from 4 ha to 100 ha (0,04-1km^2). Pairs will live in the same territory each year. They breed once a year and will raise 1-3 chicks (normally 2) each year.  Both parents raise the chicks together.  In the wild, takahē live in native grasslands and have a lifespan of 16-18 years. If snow covers the ground then they will move into nearby forests. They eat tussock grasses, sedges and sometimes rushes. But they are opportunists, so they will occasionally go for insects or even ducklings and...

Mental Health: The benefits of being in nature

Hello everyone, and welcome to this week's post! Today we thought we would talk to you on the benefits of being in nature for your mental health. This has been a much talked about subject recently, so it felt fitting that we would do a post about it. Fresh air and exercise have long been used as ways to make you feel better, whether you are suffering from a physical ailment or issues with your mental health. Just spending time outside is known to generate many positive emotions, including happiness and feeling calmer just to name a few. Over longer periods of time, it is shown to help with anxiety and depression. Although it obviously can't solve the underlying problems, it can definitely help us. However, it is less known how vital it is that the nature is 'high quality' in order to gain these effects to their full extent. This 'high quality' nature is often litter-free and clean, both of which are important if y...

March 2021 Factfile - some news from the past month, animals that YOU voted for and more!

Hi Everyone! We hope you are all okay and will enjoy this month's wrap up post. We have managed to post a little more this month but we are off school soon so we may be able to post more! News! Recent European droughts and heatwaves are said to be worst in 2000 years The British newspaper, 'The Guardian' reports that the series of droughts and heatwaves since 2014 have been the worst in 2000 years. These heatwaves have disastrous consequences such as early deaths, crop failure and forest fires. For more information, click  here . This is definitely the final bit of proof that climate change exists and that it needs to be stopped! Rise in deforestation in 2020 A horrifying 42 000 squared km of forest was chopped down in 2020, making it the third worst year since 2002. The most affected areas were humid tropical forests such as the Amazon, the Congo and other forests in South America and South-East Asia. These forests a...

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...

December Top Tips | 10 ways to re-purpose a plastic bottle

Welcome to December! We thought it would be cool to find 10 ways you can use a plastic bottle even after you have refilled it gazillion times, so you don't waste all the plastic . Because, even if you try to avoid plastic bottles at all costs, you will inevitably end up using hundreds of them throughout your life. The impact on the environment is undisputed, from the land animals to the creatures of our seas, plastic bottles can have a detrimental impact. But we can reuse them in lots of fun ways, here are our ten favourites. Have a good December and a great new year, you'll hear from us! 1. Bird Feeder At one of our blog meet-ups, we actually made a bird feeder out of an old plastic bottle, so this is definitely one we can vouch for. It's super simple, as long as you have some good scissors to cut the bottle and a suitable place to hang it. Below is a photograph of ours for some inspiration, and there are plenty of resources online to ...

Energy comparison: natural gas

Hi everyone, Today we're talking about natural gas. Natural gas is a commonly used fossil fuel. So we thought we would go over the pros and cons of natural gas. So first of all, we can quickly cover what natural gas actually is. In its natural form it's a mix of mostly methane and then some other chemical components like propane and butane. However, it's normally processed so that it's almost pure methane. Natural gas forms when organic materials (like dead plants and animals) are crushed into the ground. So it's like coal in that sense. The most popular theory is that the different conditions like temperature and pressure then control whether coal, oil, or gas is formed. Natural gas reserves are found globally. The largest gas fields are in Russia, under the North Sea, in the United States, Canada, Algeria and the Middle East. It's often found near to or even in oil fields. Natural gas is colourless, odorless, tasteless and ...
