In the 1850s, British naturalist Charles Darwin proposed the theory of evolution by natural selection. In his book, On the Origin of Species, Darwin presented years of data, notations he’d made while observing plants and animals in their natural habitats.

Over decades of painstaking observation, Darwin discovered that organisms with traits that favor survival tend to leave more offspring, causing survivalist traits to increase in frequency over time among successful species. In a word, Darwin concluded, successful survival of all living organisms requires them to adapt.

Species that fail to adapt? They go extinct, some more rapidly than others.

We are approaching un-survivable temperatures

Last year was the hottest of the past 170 years, which is when meteorologists first began tracking global temperatures. According to NASA, the 10 warmest years since Darwin’s 1850s have all occurred during the last decade, with the same predicted for 2024.

Dead monkeys are falling out of trees in Mexico. Other primates are dying, along with toucans, parrots, insects, bats and one million other species. Animals are dying from heat and dehydration at such alarming rates that even Fox News has reported on it — though they have not yet found a way to blame President Joe Biden or the border.

Last week, avoiding the words “climate change,” Fox News quoted the director of an eco-conservation park in Mexico saying they’d “never seen a situation like what’s happening right now.” The conservation park resuscitates and rehydrates dying animals for re-release into the wild, but if heat like this continues, the director predicted, “there is not going to be much we can do for the animals.”
