In the end, conservationists fall back on the "Noah's Ark Principle". That is, God told Noah to take care of all the species. ... not just those of "use" to humans, but all species including even the pests of man. Thus it's a moral argument for the rationale for protecting all species from extinction. In this case, flood control along the river must have a negative impact on this species, so we have even a greater responsibility to maintain this species and other species that are dependent on a rare flood-plain habitat. 2. What do the J and S shaped population curves indicate about the life span of an organism? Organisms that live in a temporary habitat are examples of J shape growth curve. J shape growth curve indicates that the organisms outgrow the amount of resources available and death rates increase. S shaped growth curve organisms are affected by the more organisms in the population the more limiting the environment is to population growth. Population size in S shape double as it does in J shape however as
