ugly is also in the eye of the beholder. many of us react in disgust to bugs, snakes and other critters, even some plants, that other people find fascinating and beautiful. I can’t watch those slo-mo videos of the life cycle of an insect for instance by my grandkids (both parents are scientists) are fascinated by such things, and see great beauty in them. The more you study about such “lower organisms” and their very specialized features for eating, reproducing and their beneficial effects on their environment, the more you appeciate the magnificence and power of their Creator.
some people find trees and forest beautiful, some prefer mountains, some the sea and shore, my late FIL loved the sight of plowed fields. some would be repelled by the Badlands of the Dakotas or the bleak desert landscape of say, the Big Bend or Grand Canyon areas, others see it as the most beautiful magnificent vista.
yes tsunami, hurricanes, blizzards, volcanic eruptions etc. kill people–but only the people who choose to live in zones where these things are common, and make that choice because the benefits to living there outweigh the dangers. these are all part of the natural life of the planet and climate.
every insect or micro-organism has a purpose in the natural order. without termites for example Africa would be nothing but a rotting dung heap. they process human and animal waste and return it to productive fertile soil. If humans choose to build their homes on top of termite nests, of unsuitable materials, they should not blame God for the result.
