In short: We cull the strongest and the largest (the Schwarzenegger fish) while throwing back the weak and sickly (the Steve Gutenberg fish) then when nature sees this shit go down, BAM!
Perpetual nerd fish.
The Endangered Species Act Endangers Species
The Endangered Species Act is a law passed by the United States Congress in 1973, whose main purpose is to prevent the extinction of like, four animals you've heard of, and then 800 types of skink. If your family was constantly under siege by the sinister dusky gopher frog or the malevolent dark-tumped petrel, then you were shit outta luck after '73 when it became illegal to ask them to dance with Big Betty (Big Betty being your shotgun in this strange, strange analogy). The ESA also made provisions to protect the habitats of these imperiled species by imposing restrictions on the land where they lived. This is an important point, as you will see in a moment.
Don't worry, this man is only hunting crickets.
How Did it Backfire?
As luck would have it, an estimated 90 percent of all endangered species in the United States can be found on privately owned land. When an animal on the endangered species list is found living somewhere, the surrounding habitat is automatically protected right along with it, and any activity that might harm the animal must cease. If the Fish and Wildlife Agency identifies a particular area as home to a giant kangaroo rat, for example, then farmers are restricted from tilling the soil there. Timber companies can't harvest trees. Swinger clubs have to put the kibosh on their druid-themed outdoor orgies, and somewhere the U.S. Government has to cut George Orwell a royalty check. And these restrictions stay in place until that animal is removed from the endangered species list, a proposal that can take years, decades or eternity depending on how much they like hanging out on roads, and don't like humpin'.
And animals love humping.
