How has the COVID-19 pandemic affected the environment?

Hello and welcome back to another post!

The pandemic has affected us all in many ways but what about the environment. How has it been affected? Today we'll be going into that.

How did it start?

So COVID-19 broke out in late 2019 in China but how it started is still a greatly controversial topic. Prof Stephan Turner told The Guardian in an online article in April:
[...] says what’s most likely is that virus originated in bats.
However, how it transferred to humans still isn't 100% certain. Scientists mostly agree that it didn't come directly from a bat, but instead was transferred through another animal. Regardless of how it reached humans, the main idea is that it came from a live animal, either in a food market or in the meat industry. Either way, it was our mistreatment of animals that lead to this disastrous pandemic that has claimed the lives of over 6.5 million people!


Emissions

When many businesses, industries and factories closed down, there was a rapid decrease in greenhouse gas emissions, which has been very good for the climate. There was up 50% reduction of certain greenhouse gases in China due to an industry shutdown. There was a 70% decrease in NO2 and PM2.5 in India's capital, Dehli. There was up to a 70% drop in passenger flights in China.

However, emissions went back up as the demand for face masks got bigger. The plastic in the masks needed up to 30 tons of CO2 per mask (mostly for transportation).

Air pollution

In New York, there was a nearly 50% reduction in air pollution during the lockdown, due to fewer people going out and therefore fewer cars on the roads. Car use also dropped by 40-50% in some European cities.

Fossil fuel use

According to the International Energy Agency (IEA), oil demand has dropped 435,000 barrels globally in the first three months of 2020, compared to the same period of last year

(Quote) Coal use also dropped by about 35% in the world's biggest consumer, China.


Water pollution

Due to factories in developing countries such as India and Bangladesh closing, water pollution dropped massively, or even stopped completely in some areas. The water quality became incredible within the first lockdown and is still above the levels it was before the pandemic.

Waste

Unfortunately, there was a huge increase in medical waste. Test kits, masks, medical gloves, the use of one way plastic has increased massively. A lot of which has ended up in the ocean. Read more in our article here.

Animals

As lockdowns around the world come to an end and people go back to their day jobs and school, there has been an obvious increase in the amount of abanded teenage dogs. Animal sanctuaries and rescue homes are filled to capacity. So, why? Well, during lockdown most people had lots of spare time on their hands. So what did they do? They got puppies for the family. Dog breeders saw a large increase in sales as more and more people brought young puppies. This wasn't a problem until the lockdowns stopped and people returned to work. They suddenly realised that they didn't have enough time to look after a young dog. Also, now that the puppies were no longer puppies, they were often not as sweet looking. So people just abandoned them! This is a major problem and needs to stop.

Conclusion

In conclusion, COVID was good for the environment during the first few months but soon became a huge problem due to tons of extra plastic waste in our oceans and greenhouse gas emissions in mask & testing kits factories. Also, increased internet use led to higher electricity usage in private households.

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!

November Top Tips | sustainable activities and hobbies

Hello everyone, So this week, we are going to be talking about sustainable free time activities. This area can quite big when it comes to environmental impact, so here are some things that you can do in your free time, that are more sustainable. 1. Reading So reading is one of our favourite things to do. However, books are made of paper and the paper industry isn't great. Some ways you can get around this is by reading online (for example, on a kindle), or through borrowing books from a library or using book boxes. If there aren't any in your area then at least try to support independent bookshops! 2. Running If you love being active then this one is for you. Running is probably one of the most sustainable forms of sport. All you need are some running shoes and somewhere to run. There is obviously more high-tech gear but that isn't really necessary if it's just a hobby. 3. Gardening If you've got a small area of land o...

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...

Evolution

Hi, So today, I am going to talk about evolution. We have mentioned this before in our Galapagos Ecosystem series but we’ve never gone over exactly what it is. So before Charles Darwin thought of his theory of evolution, the majority of people in Europe thought that all species were unrelated and that humans were not related to animals. This was mostly based on Christianity. Darwin studied hundreds of different species and on the Galápagos Islands , he first started to form his theory of evolution. Darwin's theory of evolution by natural selection, as it was later called, is best explained by the example of the giraffe. Let's assume that giraffes have short necks (as they did many centuries ago). Now a mother has two children. By chance, one has a slightly longer neck. This is a coincidence. As the giraffes feed on the lower leaves of the trees, these slower disappear. There aren't enough leaves for the giraffes. Thus the giraffe wi...

Animals 26-30 in our '50 incredible animals' series

Hello, Welcome back. We're very sorry for missing last week's animals. We've all had a busy time with school work! 26. Blue glaucus Also known as the blue dragon, the blue glaucus is a type of sea slug. They are small, rarely growing longer than 3cm long. Their favourite food is probably the most bizarre thing about them, Portuguese man o' war. Now, for those of you who don't already know, the Portuguese man o' war is one of the most dangerous jellyfish in the world! Different sites have different opinions, but almost all agree that blue glaucus do not hunt the Portuguese man o' war, instead they feed on dead ones or nibble away at living one! But that's still rather impressive. 27. Shoebill Shoebills are very patient and able to stay still for hours. That's how they hunt. When a lungfish comes up for air, they often don't notice the shoebill standing there until it's too late. Shoebill...

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...

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 ...

Energy comparison: solar (PV) panels

Hi everyone, Today I'm looking into the first on a long list of energy sources: solar (PV) panels. Are they actually sustainable and could they become our main energy source in the near future? After all, enough energy from the sun reaches the earth in 90 minutes to cover the entire world's energy consumption for a whole year! How they work There are a couple of ways to transform energy from the sun into electricity. The one we are looking at today is solar panels also known as solar photovoltaic technology. Photovoltaic (PV) technology is the key to solar panels. A solar panel is made of many PV cells. A single PV cell will produce 1-2 watts of power. They are very thin and are normally protected by glass and/or plastics. This is the best explanation I could find (click here for the source): When the semiconductor is exposed to light, it absorbs the light’s energy and transfers it to negatively charged particles in the material calle...

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 ...

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 ...
