it's the little things.

There are about 25 million metric tons of spiders in the world. 

Those spiders eat between 300 and 800 million metric tons of food each year. 

There are about 400 million metric tons of human in the world. 

Humans eat about 400 million metric tons of meat and fish each year. 

We don't see them very often, we usually don't like it when we do, and yet, they consume as much food as we do meat and fish. 

Yeah, it's not always the big noisy species driving around like they own the planet, that has the biggest impact.
