It covers 11.4 million square kilometres (4.38 million sq mi), which is the second largest zone in the world, exceeding the land area of the United States. [5] According to the FAO, in 2005, the United States harvested 4,888,621 tonnes of fish from wild fisheries, and another 471,958 tonnes from aquaculture. This made the United States the ...
According to a 2019 FAO report, global production of fish, crustaceans, molluscs and other aquatic animals has continued to grow and reached 172.6 million tonnes in 2017, with an increase of 4.1 percent compared with 2016. [23] There is a growing gap between the supply of fish and demand, due in part to world population growth. [24]
In the US beef production system, practices prevailing in 2007 are estimated to have involved 8.6% less fossil fuel use, 16% less greenhouse gas emissions (estimated as 100-year carbon dioxide equivalents), 12% less withdrawn water use and 33% less land use, per unit mass of beef produced, than in 1977.

The primary sector of the economy includes any industry involved in the extraction and production of raw materials, such as farming, logging, fishing, forestry and mining. [ 1 ] [ 2 ] [ 3 ] The primary sector tends to make up a larger portion of the economy in developing countries than it does in developed countries .
With capture fishery production relatively static since the late 1980s, aquaculture has been responsible for the continuing growth in the supply of fish for human consumption. [24] Global aquaculture production (including aquatic plants) in 2016 was 110.2 million tonnes, with the first-sale value estimated at US$244 billion.
No one factor operates in isolation and components of the ecosystem respond differently to each individual factor." [40] In contrast to the traditional approach of focusing on a single species, the ecosystem-based approach is organized in terms of ecosystem services. Ecosystem-based fishery concepts have been implemented in some regions. [41]
The Blue Revolution is the increase in fish and aquatic food production through the sustainable use of water resources, including marine, brackish, and freshwater systems. It encompasses activities like aquaculture (fish farming), the development of fisheries, and the sustainable management of aquatic ecosystems to provide food security ...
Conversely, one of the most unsustainable practices within the fish farming industry occurs is when farmers feed the fish pellets of animal waste. The quality of ocean water in and around fish farms is up to the farmers to maintain, and due to the fact that the mesh cages take up only a certain amount of space in the ocean, fish farmers can ...
