Are pesticides saving animals' lives?

"Kenya plans massive elephant translocation to ease human-wildlife conflict." We constantly hear news like this. In Africa in particular, animals living in the wild have to "make room", one way or the other, for a growing human population which uses low-yield, traditional agricultural methods and therefore requires much more land than if it used high-yield, modern methods involving pesticides.

Elephants and gorillas, among others, are always losing habitat to humans.

We know that occasionally birds and other non-human animals accidentally eat the pesticides and are killed by them.

The question is: what kills more non-human animals, pesticides or the alternative to them, the farming techniques which require much more land and destroy much more wildlife habitats?

Pesticides may be more good than bad for non-human animals.
