The World Development Movement has an infographic about the role of banks in food price spikes. This is a reminder of the importance of boycotting traditional banks in favor of ethical banks. According to Wikipedia, “an ethical bank, also known as a social, alternative, civic, or sustainable bank, is a bank concerned with the social and environmental impacts of its investments and loans. Ethical banks are part of a larger societal movement toward more social and environmental responsibility in the financial sector”. In short: an ethical bank is only lending money to businesses that work for a better world (social justice, sustainability, etc.)
