There is something called the food chain. And its fits the torah . Everything created by hashem has a purpose
Lets take Mosquitoes whom we all hate. What is the purpose of a mosquito. Mosquitos are eaten by other animals , who are eaten by other animals and at some point those animals are eaten by people. If the mosquitoes would died the animals higher up on the food chain would die
Birds eat alot of mosquitoes and they keep the mosquito population in check, if the birds are removed there will be more mosquitoes.
Hashem created the right checks and balances in the animal food kingdom. If we mess it up, we can create havoc.
