which animal becoming extinct would affect us the most

Any sort of insect. Annoying as they are, they are food for other animals and so on and so forth until they can get to food humans eat. They pollinate plants which give us oxygen. so bugs are the most annoying and most useful

 

Probaly any animal that helps plant vegetation/trees. We need oxygen

We could live without Cows and pigs etc.

Cows release methane when they burp and it's speeding up the process of completely fucking up our ozone.

As for milk.... Soy milk i guess, even though it has a female hormone called "Estrogen"...
People can get protein from other sources.
Pigs... I don't eat pork and they don't have much usefullness besides food. I hear pork has a lot of bad stuff in it :\

 

You read my mind, and of course most animals that we eat.
Would you consider an animal as living organisms or something else? because then I'd say plants in general.

 

Plankton aren't animals.

 

Wombat

 

pokemon

then we'd be stuck with all the shitty games D:

 

Chicken or Turkey;

How else would we celebrate Thanksgiving?

 

Gnats, people would be so much happier if they didn't exist.

 

Spiders..without them.. wed be floddde and invaded by mosquitoes and flies

 

well pandas, kangaroos, wombats

 

butterflys...........there just so pretty, how wud u be able to live without em

 

Its a mix of the green alage in the ocean, and the plankton.

But one could say the bee's/birds.

 

Bees. Wasps could go though

 

Us....lol.

 

Umm.. how about cows? I mean we get leather/steak/burgers/milk/pets out of them...

 

I'd have to say cows, chickens, and pigs because of the food they provide us with. But if people keep cutting down trees then we're gonna run out of oxygen and have more carbon dioxide so we'll also be screwed from that.
