converted to agricultural use.
The accompanying loss of biodiversity and functional ecosystems has profound economic consequences.
Emerging Global Issues: Food Security - (ANSWER)The poor of the world rely on the food they grow to

What was the Kyoto Protocol? - (ANSWER)In 1997, representatives from 125 nations met in Kyoto, Japan,
for the Third Conference of the United Nations Framework Convention on Climate Change. This
conference, commonly referred to as the Kyoto Conference on Climate Change, resulted in commitments
from the participating nations to reduce their overall emissions of six greenhouse gases (linked to global
warming) by at least 5 percent below 1990 levels and to do so between the years 2008 and 2012. The
Kyoto Protocol, as the agreement was called, was viewed by many as one of the most important steps to
date in environmental protection and international diplomacy.
What do you do when making a decision? - (ANSWER)Whether we recognize it or not, most life decisions
involve a consideration of two factors: risk and cost.
Typically, the two factors of risk and cost are interrelated and must be considered at the same time.
Most decisions related to environmental issues involve characterizing the risks incurred by people and
other living things and evaluating the cost of taking action to eliminate the risk as well as the cost of
doing nothing.
