Taxes handed to parents are funding their experimentation on human subjects at the expense of humanity.*
Importantly, parenting is an experiment just like teaching. Dunn, Lu Anne. University of Central Florida, ProQuest Dissertations Publishing, 2008. 3341009. https://search.proquest.com/openview/c299c41f6d8b743fcb6e27e14769f51e/1?pq-origsite=gscholar&cbl=18750&diss=y
Has everything been done to minimize the risks and inconvenience to research subjects, to maximize the potential benefits, and to determine that the potential benefits to individuals and society are proportionate to, or outweigh, the risks? Research volunteers often receive some health services and benefits in the course of participating, yet the purpose of clinical research is not to provide health services. ... In the United States, independent evaluation of research projects is done through granting agencies, local institutional review boards (IRBs), and data and safety monitoring boards. These groups also monitor a study while it is ongoing. https://cc.nih.gov/recruit/ethics.html
All research involving human subjects must be approved by the IRB. ... When reviewing a protocol the IRB applies three basic ethical principles: respect for persons, beneficence and justice. One of the most important parts of any human subjects protocol is the informed consent process. https://www.uaf.edu/ori/responsible-conduct/human-research-subjects/

Taxpayers, humanity, and nature need a net-zero carbon emissions plan from each welfare applicant before funding.
Funders require business plans, completed application forms, credentials, resource qualifications, documentation of logical reasoning and strategy for return on investment, and exit strategy before funding. https://www.benefits.gov/categories/Agriculture%20and%20Environmental%20Sustainability?page=3 Do welfare applicants provide enforceable net-zero carbon family plans, parenting or homeschooling credentials, resource qualifications, and documentation projecting return on investment before the government provides funding or school lunches? https://www.benefits.gov/categories/Food%20and%20Nutrition Yes, if the applicant is an organization that adds a food component to its research to control for dietary factors. https://clinicalcenter.nih.gov/nutr/nutritionresearch.html

Should the taxpayer compete against religious organizations for dependence or loyalty?
On the Pacifica radio Liberated Sisters show, Pumps On The Ground, moderated by Sister Charlene Mohammed on 1/23/21, a man said, “Most of the time, we are foolish and we buy foolish things.” A woman said the following. This is the Nation of Islam that the Honorable Pastor Louis Faracon has said to do. Buy our own land. Build homes. Build our own charter schools. Pick our own food from our own farm-acy. The money comes from Almighty God Allah.

Many Birthstrikers, the Dalai Lama, and Oriental Orthodox and Catholic priests and nuns remain celibate and childfree as a service. Anyone who can, should do that. Matt 19:12 God's Word, Names of God, and The Voice. We raise spiritual children to make wise decisions instead of bringing infants into the world.
How many of the poor deliberately bring infants into poverty in reliance upon their faith?
Do not refuse one another, unless perhaps it is just for a time and by mutual consent, so that you may devote yourselves to prayer and may then associate again; lest the Adversary begin to tempt you because of your deficiency in self-control. 1 Corinthians 7:5 World English Bible

Parenting is critical mass development.
Beinebyabo described how “critical mass development” requires “critical thinking” and “patients’ critical responsibility levels”. A Beinebyabo, Innovative Health Service Delivery in Government... (2020). https://repository.nwu.ac.za/bitstream/handle/10394/34687/Beinebyabo_A_28468740.pdf?sequence=1
How do addicts and other patients take critical responsibility for the critical mass development that United States taxpayers invest in?
For example, https://grants.nih.gov/grants/policy/nihgps/HTML5/section_4/4.2_appropriation_mandates.htm had no carbon emissions requirement for funds granted to https://h3africa.org/ in the past.
In Africa, population growth rates already exceed food production growth rates in most sub-Saharan countries, pushing them into food crises whenever bad weather, civil unrest, or war strikes. As the continent will continue to have the most rapidly growing population of any region, this will put strains on its ability to provide food for its people. ... Over the past 40 years United States development assistance efforts have played a major role in making it possible for developing countries to achieve this record. Robert W. Herdt, Assisting developing countries toward food self-reliance. Proc Natl Acad Sci U S A. 1998 Mar 3; 95(5): 1989–1992. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC33829/
Ethiopia exists today in part because Queen Candace chose a eunuch to guard the treasury. Acts 8:27
Eunuchs and birthstrikers do not create scarcity and competition by having children.
What if governments provided assistance to birthstrikers who research parenting instead of paying parents to raise children? What if the law restricted government welfare to net-zero carbon, scientific research with education, health care, and free-food components? Sponsoring birthstrikers would decrease the need for survival strategies that include childbirth. Paying subjects to participate in scientific studies that increase epigenetic markers of personal autonomy, integrity, initiative, and self-reliance would at least provide humanity with the knowledge needed for wise decision-making.

If your parents traded some of your quality of life for greater quantity of life by diluting your inheritance, you got a sibling, but did they pay the carbon tax for reducing humanity’s quality of life?
More people equals more food insecurity, soil degradation, plastic pollution and biodiversity loss. High population densities make pandemics more likely. They also drive overcrowding, unemployment, housing shortages and deteriorating infrastructure, and can spark conflicts leading to insurrections, terrorism, and war. Fundamental change is required to avoid this ghastly future. Specifically, we and many others suggest: revealing the true cost of products and activities by forcing those who damage the environment to pay for its restoration, and educating and empowering womyn across the globe, including giving them control over family planning.

Unable to pay a $50/hour bodyguard and homebuilder for protection against toxic masculinity, many celibate and childfree womyn work without pay assisting government officials in protecting people from dangerous situations including overpopulation, violence, pollution, rape, femicide, war, mob rule, domestic terrorism, and torture, not as volunteers but as slaves to the men (of all races) who perpetrated those atrocities against us and our witnesses. http://america.aljazeera.com/articles/2014/5/12/torture-report-amnesty.html
At the Davos Agenda on 1/26/2021, Atlanta Mayor Keisha Lance Bottoms said that COVID-19 adversely affected mostly individuals in crowded living situations, and that mayors need to work together and change policies allowing dangerous situations.

* Having one child costs humanity 58.6 tonnes CO2-equivalent emissions per year. We recommend four widely applicable high-impact (i.e. low emissions) actions with the potential to contribute to systemic change and substantially reduce annual personal emissions: having one fewer child (an average for developed countries of 58.6 tonnes CO2-equivalent (tCO2e) emission reductions per year), living car-free (2.4 tCO2e saved per year), avoiding airplane travel (1.6 tCO2e saved per roundtrip transatlantic flight) and eating a plant-based diet (0.8 tCO2e saved per year). For the action 'have one fewer child,' we relied on a study which quantified future emissions of descendants based on historical rates, based on heredity (Murtaugh and Schlax 2009). In this approach, half of a child's emissions are assigned to each parent, as well as one quarter of that child's offspring (the grandchildren) and so forth. This is consistent with our use of research employing the fullest possible life cycle approach in order to capture the magnitude of emissions decisions.

** The ultimate cost of carbon to humanity is approaching $100,000 per ton of carbon. An estimate for an “ultimate cost of carbon” to humanity, published in the journal Climactic Change, came out closer to $100,000 per ton of carbon. Experts agree that by the year 2100, sea levels will rise at least a foot worldwide even if we stop emitting carbon now. But by a geologist’s standards, that is only a short-term scenario. “Ice sheets take a very, very long time to settle into equilibrium,” Archer said, “so the changes we’re seeing now won’t fully be realized for thousands of years, and it could ultimately rise 160 feet.” Without the discount rate to squelch the costs in the distant future, the cost of carbon that we burn today explodes, ranging from $10,000 to $750,000 per ton based on details of the geophysical and economic scenarios.

Should birth-parents, custodial parents, foster parents, or guardians pay a carbon tax on those services or only on their carbon emissions? What if they live lives of net-zero carbon emissions stewardship, such as native forest restoration in a fire-free primitive lifestyle?

What if feminism and decolonization meant taking man out of woman and taking men out of women, in our lifestyles and attitudes, and even in the language we use? Then, wimmin could be feminine and still survive, even thrive. Until then, humanity needs to pay womyn for forced justice work. Polluters need to sponsor womin who birthstrike to save humanity from overpopulation. Colonizers need to prioritize the placement of unbonded nonreproductive womben for self-chosen work.
