In the past, there have been mass extinctions killing 90+% of life. There have been milder things like thousand-year ice ages, too.Everything in this world is getting worse, including the weather. Something as simple as bad weather, which we have always had, is getting worse. As human population increases, so does diamectrically our problems, thats a sure way to calculate this. I don't see why many cannot see this. Its academic, its getting worse, there is no numerical way to dismiss it.
Peace.
"Getting worse" needs to be evaluated in context.
