Acid Seas: A brewing disaster for economies and livelihoods 酸性の海 ― 経済と生計に起こりつつある変事

While the threat from carbon dioxide in the air has been recognized for at least half a century, the threat of this gas when dissolved in sea water has been under the scientific scanner only since the 1980s. In these three decades, acidity of sea water has increased by 12%, which is significantly affecting aquatic life. This, in turn, could have a debilitating effect on many who depend on business avenues such as fisheries and aquaculture.

An article in The Economist estimates that by 2100, rise in oceanic acidity could reach 170% of what it was barely 250 years ago. This will destroy many species in the seas, and thus destroy the means of livelihood for many people around the world.

Fisheries and aquaculture in the U.S. generated about $218 billion in 2010 and provided approximately 4.3 billion people with around 15% of their animal protein needs. Moreover, in terms of the job market, ocean-related tourism, recreation and fishing accounted for more than 2 million jobs in the U.S.

In the move toward a clean energy economy, newer research needs to be initiated to study the correlation between oceanic acidification and economic activities such as fisheries harvest.

Key Vocabularies :
