Obviously, we have only one Earth as a home for humanity, and this climate crisis can only be fundamentally and ultimately addressed on a world scale… - Bob Avakian

There cannot be a proletarian revolution if there are no class-conscious proletarians striving for that revolution.

While determined and massive struggle needs to be waged against these inhuman actions by the U.S. (and other oppressive governments), it should be clear that there can be no solution, under the system of capitalism-imperialism, to the situation involving masses of immigrants and refugees. The only solution lies in the revolution to overthrow this system—a revolution aiming not just to abolish oppression, exploitation, poverty, and misery in one country but having as its fundamental goal the abolition of all this throughout the world, and the elimination of all borders and boundaries that erect walls between different parts of humanity.

So this is another contradictory aspect of reality we have to understand: on the one hand, Marxism is the only world outlook and methodology that enables you to thoroughly and systematically and in a comprehensive way engage and learn more and more deeply about reality; but it isn't true that people who don't have the Marxist outlook and methodology, or are even opposed to it, cannot discover important truths. There's not only Darwin but Einstein and many other people throughout history, going back even before Marxism was brought into being. Obviously, such people have discovered many important truths, and that will continue to be the case, even in the socialist transition period—this is a very important point to understand or we'll make some very serious errors in the direction of bureaucratism, dogmatism, and some of the errors that we associate, for example, with Stalin.
