Biomedical waste is not limited to medical instruments; it includes medicine, waste stored in red biohazard bags, and materials used for patient care, such as cotton and bandaids. The most serious effect that biomedical waste has on our seas is the discharge of poisons into the waters that could then be consumed by ocean life creatures.
In plants, resins, fats, waxes, and complex organic chemicals are exuded from plants, e.g., the latex from rubber trees and milkweeds. Solid waste products may be manufactured as organic pigments derived from breakdown of pigments like hemoglobin, and inorganic salts like carbonates, bicarbonates, and phosphate, whether in ionic or in molecular ...
[3] [46] The Food and Agriculture Organization estimated in 2002 that over 50,000 medicinal plants are used across the world. [47] The Royal Botanic Gardens, Kew more conservatively estimated in 2016 that 17,810 plant species have a medicinal use, out of some 30,000 plants for which a use of any kind is documented. [48]
Human uses of plants include both practical uses, such as for food, clothing, and medicine, and symbolic uses, such as in art, mythology and literature. Materials derived from plants are collectively called plant products .
Some components of these toxins such as enzymes and inorganic salts are used in modern medicine. [21] For example, drugs such as Captopril and Lisinopril are derived from snake venom and inhibit the angiotensin-converting enzyme. [22] [21] Another example is Ziconotide, a drug from the cone snail, Conus magus, that is used to reduce pain. [21] [23]
Archaeological evidence indicates that the use of medicinal plants dates back to the Paleolithic age, approximately 60,000 years ago. Written evidence of herbal remedies dates back over 5,000 years to the Sumerians, who compiled lists of plants. Some ancient cultures wrote about plants and their medical uses in books called herbals.
Food recovered by food waste critic Robin Greenfield in Madison, Wisconsin, from two days of recovery from dumpsters [1]. Food loss and waste is food that is not eaten. The causes of food waste or loss are numerous and occur throughout the food system, during production, processing, distribution, retail and food service sales, and consumption.
While many plants have been used for food, a small number of staple crops including wheat, rice, and maize provide most of the food in the world today. In turn, animals provide much of the meat eaten by the human population, whether farmed or hunted, and until the arrival of mechanised transport, terrestrial mammals provided a large part of the ...
