Examples of actions that counteract the curses of the world

Counteracting Scarcity

Limit the number of consumers, that is, the population of Earth. Sustainable levels are likely between 0.5 billion and 2 billion people if the goal is for everybody to have good, secure housing, food, education, freedom of movement, and a decent level of leisure.
The necessary decrease in population size must be done in a controlled way as opposed to violent or otherwise uncontrolled (e.g. by a pandemic) ways.
MEFISDO supports having 1-3 children for everyone. Adoption, all forms of contraception, abortion up to the appearance of neocortical activity of the fetus are supported. Having children or otherwise mentoring young people is recommended, as that is the best way to propagate MEFISDO principles to future generations.
Technological advancements that result in less material and energy used to produce goods and provide services.
Recycling.
On-demand production and distribution of goods as opposed to production for warehouses.
Reducing dependence on non-renewable resources.
Expansion to other planets when it becomes feasible.

The Right to Repair for every good bought by customers must be strongly enforced.
Pollution controls.
Accept that everything, if left unattended, goes bad. That applies to food, friendships, and societies equally. Pay attention to the things around you. Feel responsible to act when needed.
Be conscious of your life. Don’t live on auto-pilot.

Doing good, reproducible science. Reproducing scientific results.
In every field of arts and science, traceable sources and citations. Cross-checking the validity of those sources.
Organizing the worlds information and making it universally accessible and useful. (Google’s original mission statement.)
Upholding and enforcing laws in an equal manner.
Keeping promises.
Making promises.
Draw lines of what behaviours you’re willing to tolerate. Your own behavior may be more restricted than that. E.g. you may not smoke but can tolerate people who smoke if they do it in a way that doesn’t disturb others. Communicate these lines.
Be conscious of your life. Don’t live on auto-pilot.
Educate yourself and others.
Do not accept authority, unless you willingly and consciously delegated parts of decision making to a competent authority.

Honest communication.
Punishing dishonest communication.
Practicing empathy.
Accepting the role of chance in everybody’s personal history while also be aware the role of decisions in the same.
Building many lateral communication pathways as opposed to a single hierarchical pathway.
Communicate to the person, not the status.
Live in a society, not as a lone wolf. Build a community not a bunker. The world is too complex to tackle it alone. Delegate making some decisions to competent authorities after carefully picking them. Review that delegation regularly and withdraw it if the authority is found lacking.

Accept that evil, as an observable behaviour, exists. Intentional violation of the MEFISDO principles is evil.
Recognize that evil is aware of all the MEFISDO principles and constantly tries to pervert them. “Pro-life”, “Freedom of speech absolutism”, “Freedom of religion” are examples of such perversions where superficial invocations to liberty are used as a smokescreen to hide large scale oppression.
If somebody speaks evil, we can assume they are willing to act evil. It is not enough to not be evil, one must not appear evil too.
Evil behaviour forfeits every right, including Human Rights. Destroying evil is necessary. Still, causing unnecessary suffering must be avoided.
