I just got the best idea - To depopulate the earth, first you must overpopulate the earth, once the earth is over poplulated to a large enough segment, then the natural course of events will take place, and with shotages its only a matter of time.... scary how easy it would be

if i wanted to depopulate the earth, i'd make Islam illegal in all developed nations. this would enrage them so much that they'd start WW3. the end.

Spray a can of Ebola-infested water in a busy airport. 50-90% fatality rate + 5-10 day incubation period = Boom!

Simple:
Just announce for weeks or months that on a certain date the government will triple your welfare check and social benefits. You tell them that they must physically stop in a prearranged location to pick up the 'special' check. When they arrive, kill them or transport them somewhere and then kill them.

People will flock to this event because since must of the world is sucking at the governments nipple, they will not be able to refuse.

I think that the best way is thru atrition.
We would need a strict sterilization program.
The idea of people picking up their welfare checks is good, but I wouldn't kill them, I'd sterilize them.
Also when a woman is in the hospital or clinic having a baby, she would be then sterilized.
Sure they could start having their babies at home, but we could deal with that later...the job is big enough already.

It would be mandatory for anyone with heritable defects to be sterilized.
We would have special schools teaching specialists how to do this procedure.

Third world/undeveloped areas would not get food or other aid. They would have to learn to fend for themselves. That alone would reduce their numbers.

I´ve given this challenge a great deal of thought. It intrigued and provoqued me to think the unthinkable.

Since I love thought challenges...

First of all, I´m assuming that the conditions of life on Earth have become unbeareable for a number of reasons: overpopulation, pollution, climate crisis and so on.

Principle: it wouldn´t be smart to "depopulate" the earth without a clear objetive: to attain better living conditions and returning Earth to a healthy state.

So...

Strategy:
- to depopulate Earth by giving it´s traditional ways a boost: using natural selection
- to eliminate all possible threats to Earth´s health

Tatics:
- create a virus of a very fast, painless and deadly disease that would kill the undernourished, unhealthy people. spread it first over countries with catastrophic living conditions (i.e. Africa).
- create a "vaccine" for common ailments (pneumonia, flu, etc) that would contain a slightly stronger strain of the contaminant agent and publicize it among the elder. Desired results: the "vaccine" would cause the illness. only the healthiest would survive.
- legalize and promote heavily the use of drugs, smoking and drinking: natural selection would quickly eliminate heavy users and cause dealers and drugs moguls to battle to death for their profits.
- at the same time, any crime commited during the influence of any drug or alcohool would mean immediate death penalty
- create a harmless bacteria that would turn whale´s meat - when dead - into an uneatable bitter goo that could cause death if eaten.
- create a harmless bacteria that would live all over living trees. When trees were hit by a chainsaw, it would spray a blinding acid liquid all around it
- All governments would pay an yearly incentive to childless couples. One child would mean the end of the incentive and two children would mean the incarceration of the mother. An alternative to that would be free distribution of anticonceptives that would unknowingly cause sterility. Poor areas of the world would receive the product with priority
- immediate death penalty to all rapists and murderers.
- poor high school reports would mean obligatory social work in devastated areas of the world

That´s all for now...
