And you are wrong.
When creatures depend upon other creatures for their survival, it is because they have adapted to their environment which is altered by that creature. We humans are a part of nature and the others animals have evolved and continue to evolve around us.
If all humans beings disappeared in an instant (like the 'rapture' of Christian fantasy), the world would be vastly different. Hundreds to thousands of species would find their environments altered. They would die off and adapt to our absence. If the removal of certain insects would leave more species unsupported, it's only because they've been there longer and more species have had the opportunity to evolve to take advantage of them.
Do you have a family of sparrows making their nest in the eaves of your house?
