I don't know about the video (I don't watch videos) but the article is correct. 90 million years ago an asteroid hit the Earth. It caused a huge crater that caused worldwide tsunamis -- and also triggered a field of supervolcanoes (called the Deccan Traps) that erupted for thousands and thousands of years, filling the air with ash and gas and pouring out huge amounts of lava.

So it was basically the Earth's natural processes that were poisoning and killing the lifeforms. And it did this because it was going on for thousands of years. All the species on the planet could survive if it was something that was over in a day or a week or a year. Maybe three years. But this went for thousands of years.
