We live in a finite world where we are consuming resources at a rate that is simply not sustainable. We will run out of life's essentials if we don't adapt. Having Kids is an organization that urges vegans to expand their view of the practice to include advocacy for better family planning: https://havingkids.org/real-animal-rights-starts-with-fair-start-family-planning. Led by famed attorney Carter Dillard, the organization would love activists to go beyond consumption and think in terms of building nonhuman inclusive futures. Having Kids is accomplishing this through implementation of a universal family planning model called Fair Start. Groups like PETA are signing on to the effort here: https://havingkids.org/organizations-joining-for-world-population-day-at-the-u-n/
