And the loss is documented where? What species died from it?
I don't care enough about convincing you to do the work required. The data is available if you care to search for it.
".... This sounds impressive until you compare it to a Super Volcano. Seventy-four thousand years ago, the eruption of Toba in Sumatra threw a total of about 670 cubic miles (2800 km3) of erupted material (about 480 cubic miles [2000 km3] of which was ash) into the air. This amount of ash in the upper atmosphere would have severely altered the temperature and weather patterns of the planet. Common estimates put it in the range of 18° to 36° F (10° to 20°C) drops in middle to high latitudes. With so much sunlight being blocked out, it is believed that a large percentage, around 75 percent, of plant life in the Northern Hemisphere was killed off and all of the animals that relied on them would have perished as well. To make matters worse, this effect continued unabated for four or five years. Some believe that this event pushed mankind to the brink of extinction, perhaps reducing the number of species to mere thousands. What of Toba today? Well, when Toba erupted it created a massive crater, called a caldera, 62 miles (100 km) long and 19 miles (30 km) wide that filled with water to form a lake. The middle of the lake floor later uplifted and formed the island of Samosir. Uplifts are not uncommon in large calderas and are attributed to the pressure of unerupted magma still trying to reach the surface...."
The last eruption of a super volcano was in Toba, Sumatra, 75,000 years ago. It had 10,000 times the explosive force of Mount St. Helens and changed life on Earth forever. Thousands of cubic kilometres of ash was thrown into the atmosphere - so much that it blocked out light from the sun all over the world. 2,500 miles away 35 centimetres of ash coated the ground. Global temperatures plummeted by 21 degrees. The rain would have been so poisoned by the gasses that it would have turned black and strongly acidic. Man was pushed to the edge of extinction, the population forced down to just a couple of thousand. Three quarters of all plants in the northern hemisphere were killed.
