The environmental impact of the paper industry - is paper really the solution?

Hello everyone,

First of all: Merry Christmas or Hannukah! I hope you are all enjoying your holidays and this special time of year. Today we'll be looking into the paper industry because lots of people are arguing about whether paper bags are better than plastic ones. We looked into it for you, enjoy!

Acid rain

In the production of pulp and paper, nitrogen oxides (NOX) and sulfur dioxide (SO2) are produced. Both of these are contributors to acid rain, which is not quite as terrible as it sounds but still quite bad. Acid rain is rain, fog, snow or hail that is acidic.
It's formed by NOX & SO2 reacting with water and oxygen which will turn them into nitrous acid (HNO2), nitric acid (HNO3) & sulfuric acid (H2SO4), meaning that instead of rain being formed from just water, it is instead also mixed with acid. While acid rain won't harm you, it can harm aquatic ecosystems and forests. When the rain falls on water, it will mix with the water and over time acidify it. This will make it uninhabitable for animals and plants. When the rain falls on trees and plants, it will kill the trees by pulling life-depending nutrients from the soil and weakens the plants' natural defence systems.

Greenhouse gases

Pulp and paper don't only produce nitrogen oxides and sulfur dioxide, it also produces CO2, in fact of the 69% of global greenhouse gas emissions that transport and energy industries are responsible for, it produces 1% of those emissions. When paper is left to decompose it releases methane into the atmosphere, and methane is 25 times worse for the climate than CO2 due to its chemical build! The paper industry also uses fossil fuels for production and transportation and it's responsible for a lot of deforestation, which in turn, is responsible for a quarter of all human-made global greenhouse gas emissions. This means that the paper industry is responsible for 9% of CO2 from all manufacturing industries. Which puts in in 3rd or 4th place for industrial greenhouse gas emissions!

Water

This industry uses a lot more water than others. A lot more means: 1 ton of paper requires 300-400 tons of water, which equates to about 20 litres of water for one sheet of A4. This water can't be used for anything afterwards, meaning that some countries will use 10% of their clean water for paper production. Often, dangerous chemicals are released into nearby rivers and lakes, which poison marine life and can contaminate drinking water.

Waste

Up to 26% of waste in landfill and dump sites is paper or cardboard and half of recyclables by weight in the US is paper. 44 million tons of paper and cardboard were recovered in 2012 alone and as already mentioned, paper waste produces methane. Out of all of methane emissions in the US, landfills are the largest contributor and equate to 34%.

Deforestation

93% of raw material in paper comes from trees. Half of that fibre comes from purposely harvested wood and the other half comes from sawmills, recycled paper and other similar sources. An average tree will give you 8 000 pages, which may seem like a lot, but if you consider that over 90% of office work is still done on paper that's not going to last long. In fact, 4 billion trees are cut down for paper every single year. That's one tree for two people! It's also 35% of global deforestation, which in a lot of cases is illegal. 42% of the global wood harvest is for paper. And we can't just grow another 4 billion trees a year because trees take a very long time to grow back, looking at it from this angle, the paper industry is not so very sustainable. 

Energy

The energy needed for one paper bag is enough for two plastic bags. The paper industry is the 5th largest energy consumer worldwide - 4% of the world's total energy output!

Chemicals

In paper production the following dangerous chemicals are produced/released:
- Chlorine & chlorine compounds
- Mercury
- dyes, ink, bleach
These gases cause dangerous air and water pollution.




In conclusion, paper isn't actually so great for the environment. However, with few good alternatives on the market, we're probably going to be stuck with it for a while. To help, you can do a lot to reduce your paper consumption. A few ideas could be

- Not using toilet paper but water, this may sound gross now, but is normal in other countries and definitely saves a whole lot of paper!

-Don't print everything! For school as well as work, not everything needs printing, that's what you have a laptop for.

-You can read newspapers and magazines online too

-Don't use paper towels to dry your hands in public bathrooms


Hopefully, you learned a lot, let us know what you think! 
Until the next post!

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

Major ocean currents and how they affect global temperatures

Hi everyone, This week we're talking about ocean currents. Ocean currents are part of the ocean's circulation system and influence local and global weather patterns. They are produced by gravity, differences in water density, winds on the ocean surface and Earth's rotation on its own axis. They cause the movements and exchanges of different ocean properties such as salinity, temperature and nutrients. Ocean currents can flow at speeds of up to 4m per second however most flow at speeds between 5cm and 50cm per second. Weather patterns and ocean currents constantly influence one another. Ocean currents follow similar paths as global wind do, transferring heat from the equator to polar regions. They create and influence ecosystems worldwide, especially marine ones. However they also spread plastics and microplastics around the world far from their original source. This system of ocean currents is often referred to as a global conveyor belt. Today w

Killing invasive species: necessary?

Hi everyone, Today's topic is a rather controversial one: is killing invasive species necessary? We'll take it apart for you to come up with your own opinion. Enjoy! Definition Firstly, let's clarify what an invasive species is. An invasive species is a species that is not native and most likely causes harm to the ecosystem where it now lives. This does not include animals that migrate to another area. Why is it a problem? Depending on the species and the ecosystem, invasive species can cause a lot of harm to their surroundings. Often invasive species have no predators in their new habitat and reproduce in such large numbers that they massively overpopulate, causing death for other species. Or they bring sicknesses the local animals are not accustomed to, and that kills them. For example black and brown rats are an invasive species on the Galapagos Islands : Black and brown rats were introduced to the Galapagos Islands in the 17th ce

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 endangered animal s

Why Don't People Switch To Electric Cars? || Green World Blog

Hi Everyone! The previous post in this series really blew up, so thank you so much for your support on that one. In this article, I wanted to discuss why people are not switching to electric cars, and why the transport industry still has a way to go in terms of reaching net zero. If you missed the first part of this post, then  click here to read it! ! I talked in the post linked above, about why people should switch to electric cars, while also taking into account the potential issues with them, and coming to a conclusion about should everyone switch to electric cars. In this post, I wanted to delve further into the topic of why people don't switch to electric cars. The cost is one of the main issues at the moment. To own an electric car, you need a reliable electricity supply, which is not readily available for everyone in the developing world, let alone the cost of buying the vehicle in the first place. The cost of the vehicle coul

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

April 2021 Factfile - some news from the past month and animals that you voted for

Hi Everyone! In this factfile we are bringing you some more news from the past month, animals you voted for, an exciting announcement and more! News: The Guardian reports that 'the new research shows that since the 1990s, the loss of hundreds of billions of tonnes of ice a year into the oceans resulting from the climate crisis has caused the poles to move in new directions.' Previously, the poles could only move due to ocean currents and other natural factors. Apparently, glacial losses accounted for most of the change but some were also due to the pumping of groundwater which once pumped up by humans isn't replaced. This shows just how much climate change is having an impact on our beautiful planet. You may have heard about M&S's plans to release 30 million  honey bees  to the countryside. It has faced many complaints from experts saying that this could damage the balance of natural pollinators. It is important t

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

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

5 Environmental Movies and TV shows

For all the TV lovers, Recently I have been getting more into watching inspiring movies and TV shows, and I started a list of environment-themed ones I want to look at. I spent a lot of time just exploring and the ones below are the ones I found. I actually haven't seen most of them, but if you have watched any of these, post a comment to let us know what you thought of it and if you would recommend it. Have a lovely weekend! 1. Tales by light - 3 Seasons This series follows the Australian photographer Darren Jew in his travels and lets the viewer explore untold stories, not all of which are nice and pleasing to look at, but nevertheless important. I saw episodes 1 and 2 of season 3, they are called "Children in Need" and are very eye-opening. 2. Into the Wild - 2 hours and 22 minutes I haven't seen this movie, but it is about a young man giving up everything and exploring new ways of life. It is based on the true story of Chri
