Ukraine struck Russia’s largest oil refinery, located in the city of Omsk, on Monday, marking what its forces say was its furthest-ever drone attack in the war.
The Omsk facility, which processes about 21 million tons of oil a year, is in Western Siberia and about 1,700 miles from Ukrainian territory — roughly the distance between Los Angeles and Houston.
most of it is icy forest where it’s too cold to do agriculture (in the north). there’s a thin latitude where the weather is good for agriculture. south of that it’s not the heat but the drought that’s the problem. up north you have shortage of sunlight, south you have shortage of water. that’s why the fertile area is narrow.
