All the solid fuels fossil energy and mineral commodities we use
come out of the Earth. Modern society is increasingly dependent on
mineral and fossil energy sources. They differ in availability,
cost of production, and geographical distribution. Even if solid
fuels, fossil energy resources and mineral commodities are
non-renewable, the extracted metals can to a large extent be
recycled and used again and again. Although the stock of these
secondary resources and their use increases, the world still needs
and will continue to need primary mineral resources for the
foreseeable future. Growing demands have begun to restrict
availability of these resources. The Earth is not running out of
critical mineral resources - at least for the near future - but the
ability to explore and extract these resources is being restricted
in many regions by competing land use, as well as political and
environmental issues. Extraction of natural resources requires a
clear focus on sustainable development, involving economic,
environmental and socio-cultural aspects. Although we do not know
what the most important resources will be in 100 years from now, we
can be quite certain that society will still need energy and a wide
range of raw materials. These resources will include oil and gas,
coal, uranium, thorium, geothermal, metallic minerals, industrial
and specialty minerals, including cement, raw materials, rare-earth
elements. A global approach for assessing the magnitude and future
availability of these resources is called for - an approach that,
with appropriate international collaboration, was started within
the triennium of the International Year of Planet Earth. Some
global mineral resource assessments, involving inter-governmental
collaboration, have already been initiated. The International Year
of Planet Earth helped to focus attention on how the geosciences
can generate prosperity locally and globally, as well as
sustainability issues in both developed and developing countries.
