From Sebastian Mallaby's article in Foreign Policy [link via Instapundit]:
"But it is also a tragedy for the fight against poverty worldwide, because projects in dozens of countries are similarly held up for fear of activist resistance. Time after time, feisty Internet-enabled groups make scary claims about the iniquities of development projects. Time after time, Western publics raised on stories of World Bank white elephants believe them. Lawmakers in European parliaments and the U.S. Congress accept NGO arguments at face value, and the government officials who sit on the World Bank's board respond by blocking funding for deserving projects. The consequences can be preposterously ironic. NGOs claim to campaign on behalf of poor people, yet many of their campaigns harm the poor. They claim to protect the environment, but by forcing the World Bank to pull out of sensitive projects, they cause these schemes to go ahead without the environmental safeguards that the bank would have imposed on them. Likewise, NGOs purport to hold the World Bank accountable, yet the bank is answerable to the governments who are its shareholders; it is the NGOs-- accountability that is murky. Furthermore, the offensives mounted by activist groups sometimes have no basis in fact whatsoever. "
