from an environmental study of oceans and heat absorption:

"In fact, the Southern Ocean alone could account for virtually all global ocean heat uptake, with the Pacific and Atlantic basins losing any heat gained back into the atmosphere.

"One significant ecological impact of strong Southern Ocean warming is on Antarctic krill. When ocean warming occurs beyond temperatures they can tolerate, the krill's habitat contracts and they move even further south to cooler waters.

"'As krill is a key component of the food web, this will also change the distribution and population of larger predators, such as commercially viable tooth and ice fish. It will also further increase stress for penguins and whales already under threat today." (my bold)

Comment: even tiny krill are important in our food web. The point is clear: every living thing plays a role in the food web. The entire bush of life, with multiple unrelated genetic forms, creates the food web and is just as important a result of evolution as the appearance of humans. The planning by design is superb: enough food for a rapidly expanding human population. It shows how God plans for the future. This website in Wikipedia shows the exponential growth since 1700 AD:

https://en.wikipedia.org/wiki/Estimates_of_historical_world_population

"From the beginning of the early modern period until the 20th century, world population has been characterized by a faster-than-exponential growth. For the period of Classical Antiquity to the Middle Ages, roughly 500 BC to AD 1500, there was also a general tendency of growth (estimated at a factor 4 to 5 over the 2,000-year period)."

Makes my case. dhw agrees we need the food, and then denigrates its importance by complaining about all the past branches of evolution that were dead ends or somehow unrelated the human directed branches. dhw is blind to the beautiful planning which anticipated human population growth.
