Technology is the knowledge of the manipulation of nature for human purposes. This implies that all practical or technical skills are ultimately derived from alterations or manipulation of nature. Furthermore, technology is the knowledge and instruments that humans use to accomplish the purposes of life. The study was conducted to review technological contributions to environmental pollution and its associated health risk, with a view to find out environmental pollution resulting from military adventurism and its effect to man and environment. In order to achieve this, proven industrial activities that depict technology related to military adventurism were discussed.

Grease is made up of a lubricant (typically petroleum oil) and a thickener (soap). The study focus on the production and characterization of grease for automobile and industrial machinery. The practicality and application of the technique were examined in order to decide whether the lithium grease produced from palm kernel oil might be used as an environmental friendly alternative to conventional grease. The aforementioned objective was achieved by mechanically extracting oil from palm kernel nuts. Lithium grease was produced through the saponification of lithium oxide with palm kernel oil. The lithium grease melting and drop points, flash point, and ash content were discussed. According to the study's findings, the lithium grease produced results that were acceptable and in accordance with ASTM standards, with the exception of its ash content, which will cause the grease to break off under pressure.
