Hungry spiders can eat every human on Earth in one year!

"While we, the undersigned, are certain the spiders are doing the best they can, it's clear that they could use some help".

Moreover, spiders are among the most effective predators of plant insects, their voracious nature turns into an excellent means of pest control. According to these two European biologists, entire spider's population of this world consumes nearly 360 to 725 million tons food.

Compare that to humans who eat 400 million tons of fish and meat each year.

The Washington Post takes it up a notch by pointing out that the total mass of all adult human beings on the planet is estimated to be 287 million tons.

A shocking new study about spiders and how much they can eat has been released. The estimations are based on research into how many spiders live on a square meter of land for all main habitat types of earth, and the average amount of food consumed by spiders of different sizes in one year. Further, they have quantified the food quantity on the basis of the size of the spider. One study suggests that globally average spider density is around 131 spiders. It's a set of numbers large enough to trigger a fear-induced blackout for anyone with arachnophobia. Similarly on the other hand, in favorable conditions, this figure might increase.

If you weighed every single spider on earth, they'd weigh about 25 million tons, according to Nyffler and Birkhofer. That's unbelievable. This is equivalent to 478 Titanic ships. By comparison, the Titanic weighed about 52,000 tonnes.

In theory, this means that if earth's spiders ever got so hungry that their regular diet of bugs and small animals didn't fill them up, they could eat every human on earth in less than 12 months.

So, moving on, spiders consume about 10 percent of their body weight per day. That's equivalent to a 90-kilogram man eating nine kilograms of meat each day.

The second method involved data from various sources in which scientists counted the number of insects that spiders actually consumed. Maybe having them around the house isn't such a bad thing after all - unless, of course, they start munching on you.
