And pesticides are also bad for other insects that don't eat the crops, and are necessary for our ecosystem to function.
And pesticides are bad for people and animals in the longer term too.
Herbicides like roundup affect a certain pathway in plants, not humans in animals.
"And pesticides are bad for people and animals in the longer term too."
Not at the concentrations that are used. The amount of residue is minuscule and modern pesticides have far less toxicity than older ones that have been phased out.
IIRC, the BT toxin only affects insects that have an alkaline digestive system. Animals and humans are unaffected as its acidic.
So now you give some qualifications to your earlier statement.
Do note that modern pesticides are not in widespread use all over the world (cost). Modern pesticides applied by a well educated professional can have a relatively low impact on the environment. But there are a lot of poorly educated farmers out there (most of them, really), and that doesn't begin to address the abuse of pesticides by lawn care companies and homeowners.
Can you source that claim?

I'm looking more for a peer reviewed study that states pesticides used in GMO farming are more harmful that pesticides used in organic farming.
