Peculation and paradox

Why has Russia's military been so weak against Ukraine? Is this a new thing or more of a case of ever thus? Antarctica is the most protected and yet the most threatened place on earth. How do we solve this paradox? Did you know that there has been a surge in saltiness in all inhabited continents today. How has it gotten this bad and have we left it too late to do anything? How quickly are wild animals evolving and adapting to problems such as climate change? Quicker than you think.
