>What if bird populations crashed and a pestilence set upon crops worldwide, and caused mass starvation & millions dead- kind of exactly like what happened during the Great Leap Forward?

Do you have any evidence at all that such a thing is likely to happen? What level of certainty that such an outcome won't happen are you aiming for? Others have noted that scientists have considered the effects of eradicating disease causing mosquitoes, and concluded that eradicating them won't to the best of our knowledge cause ecological problems. I showed evidence that around half a million people are dying every year from mosquito borne diseases. When 500,000 people are dying a year, you need more than just a vague feeling of unease not to support eradicating disease causing mosquitoes.
