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 gasses that are terrible for people and the environment.

Plastic has been found everywhere on Earth - the Arctic, the Antarctic, Mount Everest and even the Mariana Trench. It is a massive problem.

So there you are a brief explanation of how plastic is affecting the environment, including humans.

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...

Energy comparison: wind turbines

Hello, Finally, we are back with another energy comparison. Today we're looking at wind turbines. Wind power is a fast-growing renewable energy source. In the US, the wind power industry currently employs 120 000 people across all 50 states. It could grow to employ hundreds of thousands of people by 2050. 9% of the electricity in the US in 2021 came from wind turbines, that’s 136 000 megawatts. The wind power industry saves 329 million metric tons of carbon dioxide every year. General knowledge and categorisation We should probably start off by clarifying how wind turbines actually work and what types there are. I’m not going to give an in-depth description of how wind turbines work because I don’t want this post to turn into a physics lesson. To put it very simply, the wind turns the blades, which turns the rotor. The rotor then turns the generator, which converts the kinetic energy (movement) into electricity. There are obviously a lot more...

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...

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...

The life of ... a koala

Hello everyone, Today we're talking about koalas. Also known as koala bears, koalas are marsupials. So they're actually not bears. Koalas, phascolarctos cinereus , are tree dwelling and probably best known for spending most of the day sleeping. They live for up to 15 years in the wild although captive koalas generally live for longer. Koalas have a stout, gray body and a cream-coloured chest. They have a broad face, small yellow eyes and big fluffy ears. In adaptation to climbing, their feet are strong and clawed. Adult individuals in South Australia weigh 14kg and are 60-84cm big. Their Eastern cousins are considerably smaller. Koalas are found in Eastern and Southern Australia, where they live in eucalyptus trees. They feed on the leaves of these eucalyptus trees, eating up to 1.3kg a day. With a body weight of up to 14kg, this means they eat just under 10% of their body weight every single day. However, the le...

10 Animals on the edge of extinction - you did not know about No.2

The Kākāpō ~ New Zealand's green teddy bear-parrot The Kakapo is a bird mainly found in New Zealand. It is a rather curious creature, a pretty big, green, nocturnal parrot that cannot fly and looks like a mixture of a parrot, a penguin, an owl and a teddy bear. Kakapos are on the verge of extinction due to their peculiar breeding habits, predators, and hunters. They are flightless and nocturnal and are the biggest parrots in the world. They can also live for up to 120 years! History Like most living creatures, the number of Kakapos in New Zealand was healthy before humans arrived. They waddled across the islands like nothing else. However, when people came to New Zealand, they started hunting the Kakapo for its feathers, meat and skin. They also brought alien species such as rats, weasels or cats that posed a threat to which they were not accustomed to. Their survival "trick" (not really a new thing, maybe the Kakapos like it old-fashio...

10 animals on the edge of extinction you didn't know about no. 7 - tooth-billed pigeon

Hi everyone, We're back with another endangered animal. This time it's a pigeon, but not the kind that we're used to seeing in cities. The tooth-billes pigeon, didunculus strigirostris, is the only remaing species of the Didunculus genus and is one of the closest living relatives of the world-famous Dodo. The adults have chestnut coloured bodies and wings, a greenish head and neck with red skin around the eyes, reddish feet and an orange bill with a characteristic jagges tip (hence the name tooth-billed). They are 31-38cm long and weigh about 400g. The juveniles are duller with a brown head and a black bill. Tooth-billed pigeons are shy and are belived to live in small groups. These terrestrial birds are endemic to the islands of Upolu and Savai'i. They are Samoa's national bird and can be found on the local currency. In Samoa they are known as Manumea and are eaten on a local and national level, but not internationally. They ...

The limits of the Earth - the planetary boundary model

Hi everyone, So today we're talking about a model that was introduced in 2009 and has offered a new perspective to thinking about environmental issues. The planetary boundary model has 9 boundaries, each has a safe zone. Once the safe zone is exceeded, the stable conditions on our planet are considered at risk, and there can be severe and possibly irreversible changes. The nine boundaries are considered separate however, they greatly affect each other. Novel Entities describes the introduction and accumulation of man-made novel chemical compounds. These include pesticides, nuclear waste and microplastics. Stratospheric Ozone Depletion refers to the depletion of the ozone layer which was a major problem in the 90s. Atmospheric Aerosol Loading is air particle pollution.  Ocean Acidification is self-explanatory. The boundary Biochemical Flows is composed of two separate boundaries; nitrogen and phosphorus. Both of the ele...
