On a recent trip to Thailand, we were advised by the Healthy Travel Clinic to get malarial meds if were were going to the northern part of the country near the borders. We were indeed going north, but on advise from a friend who lives in Bangkok, we decided not to pay for those meds, and we're still alive since our return. However, our Thai friend and myself attracted lots of mosquito bites, in between permethrin treated clothes and 100% DEET sprays. One thought came to mind, and that is "if we annihilate the mosquito population, it would rid this world of many life-threatening diseases". Any objections? Of course, the whole 'playing god' issue comes into play. But what do mosquitos do that are beneficial to any species? The only things I've come up with so far is that they are food to spiders, dragonflies, lizards, mosquito hawks, and certain bug-eating plants. Aside from that they are carriers of death, pain and annoyance.
With all these deadly diseases that mosquitos carry, it's very clear we need to get to the source of the problem. Rather than spending billions on trying to find treatments and prevention, I say attack the source of it.
This is a hard problem to find a cost-effective solution to.
