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!

Heatwaves - what's so bad about them?

Hi everyone, Today we’re talking about heatwaves and what effects they have on us and the environment. Heatwaves are becoming ever more common, with 2023 breaking multiple world records. In China, 52.2°C were recorded at one point and the coastal waters near Florida, USA, were as warm as a hot tub. This is because of the combination of climate change and El Niño , both of which make the effects of the other worse. But we can’t push the blame onto El Niño. When analysed it became clear that without human made climate change the USA heat records would have been almost impossible. So what exactly are the effects of such high temperatures. A study in Europe found that the 2022 heatwave possibly caused over 70 000 heat related deaths. Although it is sometimes hard to tell whether or not someone died from the heat or from something else, after analysing the data the team found that their original estimate of 62 000 people (which is still a lot) was probably ...

The life of ... an alcon blue butterfly

Hi everyone, Today we are going to be looking into the life of an alcon blue butterfly (Phengaris alcon). After mating, the females lay their eggs on marsh gentian, a blue-coloured wildflower. The eggs can only be laid on these flowers, as this is what the newly hatched caterpillars will eat. Although in some alp regions, they can also be found on willow gentians, a close relative of the marsh gentian. Once the caterpillars have hatched from the eggs, their main predator and danger are the ants that swarm below. But high on their plant homes, the caterpillars are safe. However, this isn't where the alcon blue caterpillars are going to stay forever. Eventually, they drop down to the ground using silk strings. With no protection, they are soon dragged off by the ants. The most amazing part is, the alcon blue caterpillars give off the same scent and chemicals as the ant larvae. So the ants take the caterpillars back to their brood chamber, wher...

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...

Climate change: what is it and what's the problem

Hello, I've noticed that we are always mentioning climate change. Not only us blog editors but also politicians, activists and so on. The words climate change are bounced around in the media and probably in your households, but do you actually know what it is or how it works? I know that for a long time, I didn't know what it really meant. I hope that this post changes that. What is climate change and how does it work? The words climate change describe a slow shift in the earth's temperature and changes in the weather patterns. Having a single warm winter does not instantly mean climate change. Climate change happens over a long period of time. If you look at a temperature graph over the years, it doesn't go up in one day and then stay the same for another hundred years. It curves up slowly but steadily. This is a average temperature graph from 1880 to just after 2000. You can see how the temperature gradually gets warmer....

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...

13.12.2020 Animal Of The Week: Lark

Hello, Today's post is all about a rather interesting bird I don't know much about and so I can't wait to discover more! Habitat There are many different species of Lark so they are quite widespread. Different websites say different figures but most agree that there are between 90 and 100 different species of Lark. They live in open countryside from deserts to mountains. Their colour is adapted to their environment and so they can vary in appearance. Diet Larks are omnivorous animals and eat many species of insects as well as seeds, leaves, grasses and fruits, especially in Winter as insects are scarce. Some species will also eat snails which they break open on rocks. Lark Song The lark is reputed for its song, especially when it is in flight. This is the reason that they are sometimes represented in poetry. I love poetry and I haven't read any Lark themed poetry yet but writing this has made me want to. However, the wi...

Private jets - are they really as bad as people say?

Hello everyone, On social media, they will be an uproar every few months because some celebrity used a private jet to get somewhere. Today, I'll be talking about whether these flights really are as bad as they seem or whether social media is just making a big deal out of nothing. Emissions: private jets vs public flights Private jets are 5 to 15 times worse than commercial flights per passenger. Also, private flights are normally not 4 hours long, some of them are only 20 to 30 minutes! These flights are worse because taking off and landing emit more greenhouse gases . With a flight that's only 20 or so minutes, you've only got 10 minutes at the most where you're actually flying 'normally'. So when it comes to emissions, private jets are very bad for the environment. Morals You can't talk about private jets without talking about the morals involved. The first moral problem with private jets is the people who use them....

02.08.2020 Animal of the week: Owl

Hi everyone, This week's blog post is all about owls. Habitat There are many different types of owl: barn owls, long-eared owls, snowy owls and lots more. Different species live in different places. Here are a few examples. Snowy owls live in the Arctic . Great grey owls live in pine forests. Elf owls live in deserts. There are about 130 different species of owl. Owls can be found everywhere in the world apart from Antarctica . Owls live in trees, holes in the ground, barns and caves. Most owls do not migrate in winter. Diet Owls eat insects, spiders, fish, reptiles, amphibians, birds and small mammals. What they eat the most depends on the type of owl and where it lives. Screech owls feed mostly on insects. Barn owls mainly eat mice, shrews and voles. Eagle owls eat hares and young foxes. Some owls can even fish like the Asian Fish Owl. Even though some species prefer a certain type of food, most owls will eat whatever they can find...

25.10.2020 Animal of the week: Snow leopard

Hello everyone, This week's post is about snow leopards. Snow leopards are incredible big cats that roam the mountain ranges of Asia. Snow leopards are very powerful and can climb up and down steep slopes easily, as well as jump up six times their body length. The snow leopard's tail provides balance, agility and warmth. The snow leopard is elusive and solitary and therefore very difficult to spot. They are very important though, because they are at the top of the food chain in this area. Habitat Snow leopards live in northern and central Asia's mountain ranges. These are some of the harshest conditions on earth. However, they white-grey coat with large black spots allows them to blend in with the rocky mountain terrain. They are found in twelve countries including China, Russia and Mongolia. Diet Snow leopards can kill prey up to three times their body weight. This is an incredible feat to pull off as they manage this on their ow...
