No they haven't.
Some would argue that many have too much "voice" rather than too little.
Those who supposedly glue their ears to the road or trains and lorries don't speak for me or many others, yet I haven't seen any instances of their childish "look at me being so naughty" campaigns being silenced.
Bertrand Russel used to have a quote that went along these lines attributed to him but now days that is being refuted , not that it matters .
" Most people would rather die than to be made to think about the consequences of their actions .
An endeavour that way too may succeed in accomplishing "
People are inheritantly lazy
THinking is hard
So the easy lazy thing to do is agree with some one elses opinion and again way too many do just that .
There is another saying along the lines that "Emotion & passion are inversly proportion to objectivity & interlect "
Again usually true ask any self appointed saviour of the planet or passionate vegan or worse a vegan planet saver tree hugging greenie. .
We all like to take the lazy path
So when some useless pratt pedals the theory that we can bung some solar panels on the roof swap the IC for an EV then every thing will be fine & it will be life as normal we decide to believe it without question because that is the easy thing to do .
Then the deniers will say the planet is always changing and when the CO2 ratio was 10 times higher, it was the most abundant plant life in our history.
Again quite true, but there are no more dinosaurs around to eat 500kg of plant matter a day and the plants we have allowed others ( greed ) to make us dependent upon ( lazy again ) took tens of thousands of years to evolve followed by a few thousand years of human interfearance to get to where they are today and they will not survive a sudden change .
Any one feel like eating some ferns ?
The black fellas grew nardu for thousands of years , it was the base of many of their diets and traded extensively between the nations.
We ripped up the Nardu & forced them to eat wheat that we just about starved on because we could not get it to grown down here
We farm cattle that require a massive amount of work , including intensive land clearing while shooting kangaroos for dog food because they are a "pest "
Yet kangaroos are an almost perfect source of meat protien and even better as a browser do not leave barron paddocks and to top that off they self regulate reproduction so we do not have to run around shooting the off spring in drought years .
We banned eating possums, which are excellent tucker supposedly to protect them so now because they have no vaue they are considered a house invaiding pest they have gone extinct in many regions . We shot so many Koalas for export of the hides that they became extinct & only survived because of a few collonies on islands .
Worldwide the passionate illinformed got wearing natural hides banned and now 20 years latter we have found the micro plastics from the "clean green & humanitarian" replacements are a major pollutant in sea water & killing off large numbers of fish.
1/3 of the worlds ( too many ) people derrive their protien from seafoods almost excluseivly .
And I won't mention bushfires except to reinterate what another Black Fella said on TV
There were very few massive bushfires when we were allowed to care for the country and we are the living proof of that as you can't escape a raging bushfire running with bare feet .
He followed on with an intersting comment along the lines of.
You lot have got trucks, tankers, helicoperts, bulldozers, big jets , satelites , radios & computers yet with all that you can't manage to do what we did with nothing more than a couple of branches .
