In 1995, 14 wolves were released into the wild in Yellowstone National Park. Scientists at the time did not suspect that this would radically change the entire ecosystem of the park. 1/n Image
There had been no wolves in Yellowstone for 70 years. During this time, the deer population grew tremendously, severely damaging the local flora.
2/n
Fourteen wolves, of course, could not eat all the deer, but they forced the deer to be more careful in choosing places to eat, and to avoid certain parts of the park. In those places, vegetation began to revive. 3/n
In six years, the number of trees increased fivefold. Beavers appeared and began building dams. Muskrats, ducks and fish bred in the new ponds.
4/n
The wolves reduced the population of jackals, which led to an increase in the number of hares and mice. This in turn attracted hawks, ferrets and foxes to the park. Bears thrived on the scraps of prey left by the wolves. 5/n
Remarkably, the wolves also changed the flow of Yellowstone's rivers. River channels straightened and stabilized, and coastal erosion decreased. This happened because the influence of wolves on deer led to the explosive growth of trees along the banks of the rivers. 6/n
The story of the Yellowstone wolves shows that ecosystems are complex and interconnected in ways that we may not fully understand. When all the parts are in balance, nature thrives. 7/end
Correction: Coyotes, not jackals.

One little-discussed aspect of the Russia-Ukraine war is that it is accelerating the world's transition away from using the U.S. dollar as the global reserve currency. 1/2 asiatimes.com/2022/03/gold-w…
The unprecedented sanctions put on Russia's Central Bank make holding dollars a non-starter for many countries, especially China. 2/2
So demand for USD will fall. USD will depreciate, making imported goods more expensive for Americans. Inflation will get even worse. 😱

Trudeau has been forced to abandon his Emergency Act as a staggering amount of money has fled Canadian banks. Canadians have moved accounts to the United States by the tens of thousands following Trudeau’s freezing of bank accounts without a court order. 1/x
Canadians began withdrawing all of their money from their bank accounts with most turning to cash, others to gold, and some to BitCoin. The demand for US dollars more than tripled in the past week. 2/x
Trudeau’s freezing of bank accounts has undermined confidence in the banking system. Rescinding the Emergency Act is not going to make it all better. Trudeau has driven a stake through the heart of Canada’s economy. 3/x

Below is Putin’s speech explaining Russia’s decision to recognize the DPR and LPR as sovereign states, and Russia’s decision to defend them. It makes interesting reading. Here are the highlights. 1/x en.kremlin.ru/events/preside…
Putin notes that Ukraine “is an inalienable part of our own history, culture and spiritual space. These are our comrades, those dearest to us – not only colleagues, friends and people who once served together, but also relatives, people bound by blood, by family ties.” 2/x
Putin then goes into a long digression on the early history of the USSR, faulting the Bolsheviks for creating the fiction that the country’s republics were semi-sovereign states, which fostered nationalist ambitions in places like Ukraine. 3/x
