Weather patterns
influence the availability of water resources and the potential for forest fires;
earthquakes, volcanic eruptions, hurricanes, and floods can kill large numbers
of people and cause millions or even billions of dollars in property damage.
Just as Earth systems directly affect each of us, we — as
individuals, communities and nations — affect our planet. Expanding
technologies and growing populations increase demand on natural
resources. As we extract and use these resources, we impact Earth
today, which will in turn impact those who come after us. To
enhance our stewardship of the environment, we must proceed
into the future with a sound understanding of Earth systems.
