Abundance conjecture for varieties of Kodaira dimension minus infinity

Let $Y$ be a smooth projective variety. A variety is uniruled if through a general point of $Y$ there passes a rational curve. Abundance conjecture. If $\kappa(Y)=-\infty$, then $Y$ is uniruled. This is the second standard conjecture recalled in the source as part of the minimal model program and abundance framework.
