Having traveled through some of the most impoverished countries in Africa, and in particular some riddled with malaria, I wholeheartedly endorse this fundraiser. And not just for lives saved. Don't forget the emphasis on 1000nets = 1 life. I would personally emphasise the fact that nets massively improve livelihoods. Most people can't afford malaria treatments....sometimes they are available to them, but at a small cost! I passed many places that sold it (and rued paying exhorbitant prices in Australia for mine prior to departure, haha), and to an employed westerner, its dirt cheap to treat someone for malaria. But its not to them.
Most adults I spoke to had had malaria, or dengue, at least once, often many many times. They just have to ride it out. If they are fit and otherwise mostly healthy by local standards, then this might take a few weeks. Its basically lazing around with a bad bad man flu. They can't work though, or look after their families, or study, and of course its very risky, they could still die or develop complications, and without a mosquito net over them, they help to pass on malaria to more mosquitos to infect more people...
Could you imagine the affect on your livelihood if say, once a year, you had to take 6 weeks of unpaid sick leave, completely laid up in bed at home? It would be bad hey.
Now imagine you are struggling just to feed yourself and your family a meal a day, find clean water, etc. Its critical. Everyone suffers around you too.
Good on you all!
