To illustrate my point, the 2006 drought in Australia decimated wheat production by up to 60%. Experts predict that the effects of global warming will not only place additional pressures global food production but also threaten global harmony, such as by rising sea levels due to the melting polar caps, changes in sea currents and worsening droughts in many countries.
For us in developing countries, these threats are extremely serious because they directly relate to the ability of underprivileged peoples to deal with shocks and natural disaster. We are aware that global warming is a reflection of global externality where the negative impacts do not stem from current trends but from an accumulation of past and future events.
