Given the task definition and input, reply with output. You are given two sentences. You have to find if there is entailment or agreement of the Hypothesis by the Premise. From the given pair of sentences, you should identify if there is enough information in the Premise to support the claim made in the Hypothesis. The Premise may not exactly be the same as Hypothesis. Your task is to return 'entails' if the premise supports hypothesis else return 'neutral'.

Premise: As populations increase above the carrying capacity of the environment, certain density dependent mechanisms kick in to reduce population size. 
 Hypothesis: Humans are unique in their ability to alter their environment with the conscious purpose of increasing carrying capacity, which acts as a limiting factor on populations in general.
