Polar bears can’t hunt on land to survive

Polar bears have been at the center of the climate change debate over the course of the last several years. They have been one of the biggest victims throughout the global warming process that has left the population of polar bears dwindling in the coldest places on Earth. In fact, it has gotten to a point now where scientists are learning more, and more about the bears – and how ill-equipped they are to handle hunting when the ice continues to melt.

Polar bears primarily hunt on ice to get to fish and other marine life that exist in the open water. If they do not have access to the ice – then they do not have access to their food supply, and being given the ability to hunt on land doesn’t make their food source any less scarce. In fact, it pretty much makes their situation a thousand times worse. It leaves them eating bird eggs, berries, and other non-sustaining things, which ultimately leaves them withering away, and dying off from starvation – in addition to changing climate.


Karyn Rode, the lead author of the study pointed out that, “A really large bear has high energetic costs when they get up to forage, and these [terrestrial] resources are typically lower in calories or widely dispersed.” The problem right now is that feeding on land has been a contingency plan that has been considered by conservationists to allow polar bears to continue living a normal life. However, this study throws that logic out the window and leaves researchers looking for alternative methods.


At the end of the day it’s about determining what methods can help the population move forward while climate change is hopefully addressed. Rode said, “If terrestrial feeding can’t help, there are other things we need to be thinking about.” This is now the mission that scientists face, and conservationists face, as they move forward and try to determine what will be best for everyone moving forward.

  • The spam comment by Mark Goldes advertising his fraudulent so-called “AESOP Institute” is a typical example of the thousands of false and fraudulent spam comments he has posted to advertise his sham “Institute,” which has been his instrument to defraud people with false and empty claims of make-believe “breakthroughs” for many years. Mark Goldes has no “surprising new science” or “revolutionary technology,” and is not “prototyping” anything at all – all he has is the same old fraudcraft he’s been deceiving people with for decades – first at MPI, and then at Chava Energy LLC and his so-called “AESOP Institute.” He does not have any “breakthrough technologies” or any engine that could run on the single heat reservoir of atmospheric heat. Every heat engine requires two heat reservoirs at different temperatures in order to do any work. Goldes’ pretended “fuel-free piston engine” concept is not worth a nickel, as he knows very well. He has no “fuel-free engine” that could work at all. He has deceived and defrauded gullible people for decades with his endless empty claims of make-believe “breakthroughs,” by persuading them to give him loans, which he never repays.

    Inertia will see Global Warming inevitably reach 1.5 degrees C. At the present rate of increase the planet will reach 2 degrees C in 10 years – possibly the maximum temperature allowing humans to flourish.
    Breakthrough technology is needed to replace fossil fuels much faster.
    This requires new science – hard for most scientists and engineers to believe. Much of it threatens powerful vested interests.
    Examples are Cold Fusion (Low Energy Nuclear Reactions) and BlackLight Power’s cheap green generators.
    Engines have been invented (and prototyped) that need no fuel. These engines utilize atmospheric heat, an enormous reservoir of 24/7 solar energy. See: aesopinstitute.org
    Survival on a livable planet suggests we need round-the-clock production of every viable renewable energy alternative.
    Shortly after Pearl Harbor was attacked, Willow Run had a 4 engine B-24 bomber roll off the line every hour.
    We managed to reach the moon in 10 years.
    Surely, with the survival of every man, woman and child at stake, we will make it happen!
