10 Animals Most Could Do Without

Some would say the world would be a better place without certain animals. Most of these animals serve no purpose but to harm, make others sick, or work hard to keep them alive.

1. Ticks

Most tick bites are painless and cause only minor signs and symptoms, such as a change in skin color, swelling, or a sore on the skin. But some ticks transmit bacteria that cause illnesses like Lyme disease.

One user stated, “I tell people all the time that the most dangerous animal around where I live is not a bear, Coyote, or wolf, but rather a tick. If they just vanished tomorrow, I don't think there would be that much ecological disruption. However, a case could be made that they help keep large mammal populations in check by slowly killing them.”

2. Bed Bugs

Bedbugs are like a plague, and they have no redeemable virtues. One user said, “I am currently spending thousands of dollars and countless hours of labor on getting them out of my house. And don't get me started on the bites and itching.”

Another user commented, “Bedbugs can be found anywhere. Public transportation, doctor's offices, schools, and even restaurants. They are now on every continent except Antarctica. Seventy years ago, they were almost extinct, but then the pesticides stopped working so well, and here we are.”

3. Panda Bears

Some people feel that if an animal serves no purpose, then why does it exist? That is where the panda bear falls in. Pandas seem so cute and playful, but also, they have the brain power of a rock.

One user stated, “The Panada bear only eats the most nutritionally useless of plants, but neither its teeth nor digestive tract is properly adapted to that food source. As a result, it has to spend all day literally eating just to avoid starvation. It is an evolutionary failure. People just need to let it go.”

4. Spotted Lanternfly

The spotted lanternfly kills most trees and flowering vines, extensively damages fruit and berry trees and shrubs, and can kill many food crops. While it is rather pretty, this bug doesn't seem to serve any other purpose.

One user advised, “We just got these in my area for the first time last summer. They had been in most of the counties surrounding me for a while before that, but it took a while to make it here. So I got my four-year-old in on the “stomp this bug” game, and he loved it.”

5. Mosquitoes

Most people are unaware, but there are over 3000 species of mosquitoes, and most of them do not bite and suck your blood but rather pollinate flowers. But the ones that do bite not only leave an itchy bump but can also spread diseases.

6. Seagulls

One user reports they wish seagulls would become extinct. With their description of the bird, it's no wonder they are scared of the bird, “they have lifeless eyes. Black eyes. Like a doll's eyes. They don't even seem to be living when they come at you.”

7. Leeches

Most leech bites are harmless. Usually, the leech can be removed easily without medical attention. But the bite can cause extended bleeding at the attachment site even after removing the leech. This is because the saliva from leeches is an anticoagulant and interferes with the blood's normal clotting.

This does not mean people don't wish they would become extinct. One user explained, “we had a lake a few blocks from where I grew up. As kids, we would go swimming there until one day, one of us had a leach on them. Then our parents wouldn't let us go back.”

8. Salt Water Crocodile

Reports have shown that saltwater crocodiles are more aggressive than their freshwater counterparts and can be three times bigger. This user sums up their feelings, “just no! The ocean already has scary animals like sharks, jellyfish, etc. Do we really need another sharp-toothed creature in there?”

9. Koala Bear

Looking at the face of a koala bear might make just about anyone smile. But some people think they're useless contributions to the world, and the fact that we must ensure they don't become extinct means we should let them go.

One user answered, “Koalas only eat three types of eucalyptus. And if left alone in a locked room filled with multiple kinds of eucalyptus plants that aren't any of the three they prefer, they'll decide to sit there and starve to death, even though food is abundant. They're that picky.”

10. Jellyfish

The way a jellyfish swim is so dainty and angelic. These creatures move so swiftly, like they're dancing in the water. But some people wish they, at least the ones harmful to humans, would be extinct. Several jellyfish species have long tentacles that can inject venom.

One user reported, “They also have no heart, bones, or blood and are around 95% water. However, they have a basic set of nerves at the base of their tentacles which can detect touch, temperature, salinity, etc.”
