The world should have only one government rather than a national government for each country. Do the advantages of this outweigh the disadvantages?

The world should be governed by a single administration

instead

of having different state control for each country.

Although

it may sound beneficial on the surface level, I believe

this

idea is largely problematic and unattainable. Advocates of the practice may think of the opportunity as a means to galvanize global efforts for large-scale problems, climate change, or health crises

for example

. A centralized government could better protect the environment by enacting strict legislation against the burning of fossil fuels and force all citizens to get vaccinated against Covid-19. Seemingly, gathered support from every country around the world seems to weigh more than national attempts when dealing with these serious worldwide issues, so in hypothetical terms, so unilateral a power could have a lot of potentials to achieve a tremendous end.

However

, it is nearly impossible for every country to agree on one government in the reality. The world now has many regimes that are run by distinctive ideologies,

such

as communism, socialism, capitalism,...; these by far do not seem to mix well in a combined leadership, so conflicts between groups of different believes will be inevitable.

Furthermore

, humans are psychologically and naturally bound to have distinguished ideas on just about everything,

thus

enforcing every person to follow a single way of ruling is against the freedom of ideology pursuit,

therefore

go against basic human rights. In conclusion, a single government for the entire planet could help resolve global issues but would ultimately contradict the fundamental values that we have constructed in the history of human society.

As a result

, the mentioned idea might propose more problems than possible merits.
