[212] [225] [226] Dairy and fish and/or specific types of other foods and/or supplements contain omega 3, vitamin K 2, vitamin D 3, iodine, magnesium and calcium, many of which were generally lower in people consuming types of plant-based diets in studies, [227] [228] though meat-eaters were also shown to be at risk of nutritional deficits.
Tribal people historically used various plants for medicinal and food exploitation purposes. [4] Use of fish poisons is a very old practice in the history of humankind. In 1212 AD, King Frederick II prohibited the use of certain plant piscicides, and by the 15th century, similar laws had been decreed in other European countries, as well. [5]

This is a sum of 93.5 million tons of wild animals and 62.7 million tons of farmed animals. 56.8% of this total was freshwater fish, 6.4% diadromous fish, and 3.2% marine fish, with the remainder being molluscs, crustaceans ...
Water pollution: This is the contamination of water by human activities. Water pollution can lead to the death of fish and other aquatic organisms, and the spread of disease. Loss of biodiversity: This is the decline in the number and variety of plant and animal species. Loss of biodiversity can have a number of negative impacts, including the ...
The environmental impact of agriculture involves a variety of factors from the soil, to water, the air, animal and soil diversity, plants, and the food itself. Some of the environmental issues that are related to agriculture are climate change, deforestation, genetic engineering, irrigation problems, pollutants, soil degradation, and waste.
Food waste can also be used to produce multiple high-value products, such as a fish oil substitute for food or feed use via marine micro algae, [150] without compromising the ability to produce energy via biogas. The general consensus currently suggest that reducing food waste by either prevention or valorisation, for human consumption, infers ...
Cyanobacteria (blue-green algae) bloom on Lake Erie (United States) in 2009. These kinds of algae can cause harmful algal bloom. A harmful algal bloom (HAB), or excessive algae growth, is an algal bloom that causes negative impacts to other organisms by production of natural algae-produced toxins, water deoxygenation, mechanical damage to other organisms, or by other means.
Fish farming or pisciculture involves commercial breeding of fish, most often for food, in fish tanks or artificial enclosures such as fish ponds. It is a particular type of aquaculture , which is the controlled cultivation and harvesting of aquatic animals such as fish, crustaceans , molluscs and so on, in natural or pseudo-natural environments.
