Guyana's long-struggling economy was radically transformed in 2015 with the discovery of a rich offshore oil field in the country's waters about 120 miles from Georgetown. By the end of 2020, another 17 oil fields had been found in Guyana's Stabroek Block, and it was projected that by 2025 these fields would be yielding some 750,000 barrels of oil per day.

Bauxite ore is the main source of aluminum.: 65 Bauxite is a variety of laterite (residual sedimentary rock), so it has no precise chemical formula. It is composed mainly of hydrated alumina minerals such as gibbsite [Al(OH) 3 or Al 2 O 3. 3H 2 O)] in newer tropical deposits; in older subtropical, temperate deposits the major minerals are boehmite [γ-AlO(OH) or Al 2 O …
Biological pest control is a method of controlling pests such as insects and mites by using other organisms. It relies on predation, parasitism, herbivory, parasitody or other natural mechanisms, but typically also involves an active human management role. Classical biological control involves the introduction of natural enemies of the pest that are bred in the laboratory and released …

(Source: Wikimedia Commons) Municipal programs to recycle materials such as paper, glass, plastic, and metal are one way to decrease the amount of resources (especially non-renewable ones) needed to produce a given amount of products, but it may not ...
leaching, in geology, loss of soluble substances and colloids from the top layer of soil by percolating precipitation. The materials lost are carried downward (eluviated) and are generally redeposited (illuviated) in a lower layer. This transport results in a porous and open top layer and a dense, compact lower layer. The rate of leaching increases with the amount of rainfall, high ...
