Wich one and why don´t think too much into what would cause to nature not having that particular species, I without a doubt choose the Mosquito, they don´t serve any porpuse in nature as far as Im concern but to annoy people and cause diseases, I don´t really care if they help some big animal back problems by biting their bacteria or something, also is there any reason to why the buzz in your ear other than annoy the ever living hell out of you? dosn´t that just make you aware of their presence, maybe where the mayority of you live there are not mosquitos (tropical wheater countries yay!) and you may not think they are all that harmfull but they are and probably more than racoons that I kinda predict that some of you are going to pick, long story short I don´t like mosquitos and not having them in the world wouldn´t change anything in any meaningfull way, sucks for Jurassic Park ... so wich Animal/Insect would you like to cease to exist.
But man, I really hate those cats what ain't got hair. I'd get rid of them.
EDIT: Also, I'm pretty sure that insects are under the Animalia Kingdom, which makes them animals, which makes the /insects part of your thing unnecessary. And yes, at this point I'm just nit-picking.
As much as I fucking despise spiders and them being the only animal/insect I fear, I'm not sure if I would remove them. Other insects would be way more common if spiders weren't around killing and eating them. If the mother-fuckers would just keep out of my house I wouldn't mind them so much, but they always get in here! Anyways, if I was going to erase one, it would possibly be spiders, alternatively it would be mosquitoes because of the major part they do in spreading disease and doing not a god damn thing useful that I know of.
I think this thread is just turning into a list of animals the planet needs.
Well i don't think this is a serious debate about which life form the planet could do without, i think its pretty obvious how important the stability of a proper ecosystem is..................I just hate fucking spiders.
Brown Recluses (aka Fiddlebacks). I'm generally not scared of spiders, but fuck those things in particular. They're ALL OVER in my neck of the woods, and they've probably started moving back into the house now that it's getting chilly out.
Brown Recluses are the worst. Holy shit.
What!? , ants are great they eat dead insects (sometimes killed by them), and everything they do they don´t leave a mess after they eat whatever little piece of food you drop on the floor , If you don´t disturb them they just leave like they came in a orderly maner , when they get into stuff that you got stored that is when they cross the line but there´s some weird symbiosis with the ants in my house , just keep everything well sealed.
