Here's evidence that contradicts your statements about nothing getting done because of PR ([source](https://www.fairvote.ca/2018/10/24/evidence/)):
_"\[...\]__ Looking at a number of specific indicators, Lijphart found that in countries using proportional systems: _
* _Voter turnout was higher by 7.5 percentage points, when contextual factors are taken into account._
* _Government policies were closer to the view of the median voter._
* Citizens were more satisfied with the performance of their countries’ democratic institutions, _even when the party they voted for was not in power._
* _There was a small increase in the number of parties in Parliament._
* _The share of women elected to legislators was 8 percentage points higher._
* _Scores were higher on measures of political participation and civil liberties"_
And some more data, specifically about the environment ([source](https://www.fairvote.ca/climate/)):
_"Countries with proportional systems tend to act more quickly and do more to protect the environment. These countries:_
* _Acted earlier to protect the environment_
* _Scored higher on the environmental protection index_
* _Slowed the growth of CO2 emissions five times more effectively_
* _Have made 117% greater use of renewable sources of energy."_
Correlation does not equal causation, but still, the correlation is strong, and it helps that it's supported by theory (most political scientists support proportional representation voting systems).
