1. The Title should be "Norway became a global salmon behemoth. Now it's facing the consequences". It fits the character limit, why change it?
2. A lot of the conditions for Salmon farming can be drastically improved or completely eliminated if they have done it further away in deep sea rather than coast. It just cost more.
3. China is rapidly improving their Salmon Farming so there isn't much to worry about for Norway. In 10 - 20 years time half of it will be gone.
Points 2 and 3 kind of contradict themselves though, as China doesn't have access to deep sea (at least until the invasion of Taiwan or if China manage to take control of their claimed share of South China Sea).
You can farm fish outside territorial and exclusive economic zone waters. But in any event China has substantial EEZ waters: https://www.marineregions.org/gazetteer.php?p=details&id=848... Taiwan isn't much of a hindrance. For one thing, the Strait is 100 miles wide. And China's coast is much, much longer than Taiwan.
They are doing both landlocked and mobile deep-sea methods farming with success. In typical Chinese fashion as they have done with Fruit and other food productions, I wouldn't be surprised if they could scale it 10x within 5 years. I doubt it will take away Norway's supply to Japan in the short term due to quality and trust issues. But export to China may be lowered.
China has the world’s largest distant-water fishing fleet, and Chinese vessels fish far beyond China's coastal waters like in South America, West Africa, Indian Ocean.
That's an interesting fact but that does not tell me anything about the possibility it has of raising salmon in its own waters
FYI it’s “dramatically improved” not “drastically improved”. Drastically has the connotation of something bad happening so it doesn’t make sense to drastically improve something, it’s like saying “horribly benefited”.
The connotation of drastic always being negative is through common usage and not strict definition. See: https://www.merriam-webster.com/dictionary/drastically
Using drastic in this instance is an appropriate, but rare, usage in a positive sense. You are correct that dramatic would be a more commonly used neutral synonym, but using drastic is technically just fine here. It is only slightly odd usage by common practice, but as a native english speaker I hardly noticed it until you pointed it out.
By using a less common word and outside of the common usage of that word, to my ear this adds emphasis, like reading the word in BOLD text or capitalized.
I think it is a very weird phrasing in this context
"drastically improved or completely eliminated"
because drastically often is a negative, improved often is a positive and increase, using a two word phrase were both words are essentially opposite of their common usage seems almost linguistic malpractice.
It would make much more sense to say either drastically decreased or dramatically decreased since the Or in the phrase indicates complete elimination.
Not really, as people in some dialects do so horribly/terribly improved. Drastic doesn't even mean bad per se, it just means extreme.
