The level of damage you will inflict on functioning eco-systems by "engineering" predators out of the equation will be truly catastrophic. What you might not realise is that by removing predators you will also have to change each and every other animal or organism that is currently alive in the world. You are talking about re-engineering almost all living creatures on our planet.

Let me explain by way of an example that is close to home for me. In my country of birth we have many areas which normally used to have free roaming wildlife including predators like lions and leopards. These areas where subsequently taken over as farm land and the big cats removed. This allowed the pray, usually antelope and other herbivores, to breed out of control causing immeasurable damage to the vegetation and if left unchecked would cause these animals to die of starvation in the end. It might sound far fetched but these ever increasing herds do cause damage to the vegetation if their numbers become too big. Given this situation farmers and conservationists either have to organise regular culls of these animals or capture and relocate them. Unfortunately there is only so many place you can relocate them to before the natural environment cannot accommodate them anymore and starvation due to destroyed vegetation sets in.

Predators in these natural eco-systems serve a very necessary function.

I am not talking about Human predators here so please dont confuse the above example with justifying why some human beings prey on others. Human predators need to be removed from our society. We are not animals and have the ability to reason which sets a different standard for us.

What I am trying to illustrate is the logical conclusion of your very well intended desire to reduce suffering. I applaud your desire to reduce animal suffering, of which we humans have a lot of blame for, but to extrapolate that to natural eco-systems could have disastrous effects.
