If Conservation of resources goes wrong, nothing else will go right – M.S. Swaminathan
Renewable geological resources
Renewable geological resources can be reproduced through natural regeneration. The timespan and place for the regeneration process are varied depending on the resource types. The examples of renewable resources are water and soil. Soil regeneration is influenced by chemical, geological, hydrological, and biological processes. While water regeneration is controlled by the hydrological cycle that are influenced by solar energy, climate, and topography. Although water and soil can be regenerated, excessive extraction of renewable geological resources exceeding their capacity can cause depletion of the resources and even worse the extinction. Sustainable use of renewable geological resources requires extraction rate less than the regeneration of these resources or innovation of reusing the resources (recycling).
Non-renewable geological resources
The example of non-renewable geological resources are coal, petroleum, natural gas, rocks containing metals (iron, gold, copper, silver, lead, manganese, zinc) and non-metallic rocks. Non-renewable geological resources will be depleted when they are continuously extracted due to the long geological formation of these resources (millions of years). The use of non-renewable geological resources today will surely reduce their reserves and availability.
Indonesia as an archipelagic country has abundant geological resources, both renewable and non-renewable geological resources (read the article: Geological resources of Indonesia).
However, after reading this article, it can be concluded that the extraction of Indonesia’s geological resources should be conducted sustainably so that the environment and availability of the Indonesian geological resources could still be utilized by future generations. Moreover, the best scientific and technological approaches are needed to manage and to extract effectively and efficiently. Finally, we must actively participate in the move on protecting our nature and resources, and striving to find non-conventional sources of energy for Indonesia’s better future.
