Question

The blue revolution is associated with
A. Fish
B. Milk
C. Flower
D. Litmus

Answer 1

Blue Revolution is the term given to the emergence of aquaculture, it is one of the most important forms of agricultural activity. It started from the 20th century to present, particularly in underdeveloped countries. Since late 1980s due to technological innovation and lack of capturing aquaculture production shoots up and grown exponentially and now represents the main source for global fish supply for direct human consumption and other purposes, and it is a critical part of the global food system.The Blue Revolution and expansion of aquaculture is expected to continue to grow, it may increase by approximately 30% by 2030 from current levels.

Complete answer:
The Blue Revolution is defined as the significant growth of global aquaculture production. It includes domestication and farming of various aquatic organisms such as fishes, shellfishes, and aquatic plants- from the middle of the 20th century to present, particularly in underdeveloped countries.
Before the 1980s, global fish supply from aquaculture did not constitute a significant food source.However, depletion of ocean fisheries and subsequent decline of capture fishery production caused aquaculture to shoot up.
Aquaculture production increased by more than 50% globally from the mid-1980s to 2000 and cemented itself as a significant source for global fish supply.Since 2000, aquaculture has been the fastest growing food production sector, growing 5.8% per year, supplying over 100 metric tonnes of fish, shellfish and seaweeds 425 species in 2017.
The Blue Revolution helped to improve availability and accessibility of farmed fish in some regions, therefore potentially improving nutrient and food security, especially in poor nations and rural populations.
Blue revolution is only associated with aquatic organisms; it has nothing to do with Milk production or Flower or Litmus.

So the correct answer is option A. Fish.

Note:
Aquaculture boom has decreased the prices of fishes and other aquatic organisms so it is affordable for the poor people to buy it. Fish is a good source of omega 3 fatty acid, vitamin D, iodine, iron and calcium so fish consumption helps in preventing various disorders in humans and in maintaining good health. It also helps in reducing poverty especially in the rural areas because it is easy to culture and cost effective.
