The purpose of ESA, from it's very own text: "The purposes of this Act are to provide a means whereby the ecosystems upon which endangered species and threatened species depend may be conserved, to provide a program for the conservation of such endangered species and threatened species, and to take such steps as may be appropriate to achieve the purposes of the treaties and conventions set forth in subsection (a) of this section." [source]
There's 48 pages of text in ESA but the main point is clear - to protect and conserve endangered species and the habitats and ecosystems the populations rely upon. Wikipedia puts it pretty clearly: "The ESA's primary goal is to prevent the extinction of imperiled plant and animal life, and secondly, to recover and maintain those populations by removing or lessening threats to their survival." [source]
There's ~2000 species listed in the ESA, ranging from large charismatic megafauna like the Whooping Crane, to amphibians like the Wyoming Toad, to plants like the Texas poppy-mallow.
There's only one problem with the ESA, in my opinion, and that is only that it needs to exist in the first place. If humans hadn't messed everything up in the first place and destroyed habitat, polluted environments, and hunted animals to near extinction then we wouldn't even need ESA. Therefore it's our responsibility to make it right and protect and conserve these species that are on the cusp of extinction. We need to atone for our mistakes.
Even if I've never heard of or seen a particular plant or fish or frog or bird, I know there's an intrinsic value to having that species on this planet, regardless of my existence. In ecology, the intrinsic value of a species is the value of the species itself, not the worth of the species in relation to humans.
Who are we to decide which species get to survive because they're "useful" while also condemning others to extinction because they are not "useful" to us?
Follow me on this thought experiment for a moment. Does a Mallard have more right to survival than the Wyoming Toad? Mallards are not endangered, are hunted, provide food, and are managed to keep a sustainable population going for the sake of the species but secondarily for the sake of the sport. The Wyoming Toad is tiny, very rare, and of no economic use. Does one species deserve to exist more than the other?
No.
We should do everything possible to conserve these species on the brink of extinction because every species is valuable in its own right.
