Or are you arguing that the government should have no accountability, oversight, responsibility or say in any of the activity of it's citizens?
It's not up to the plaintiffs to say what specific thing the government or individuals should or should not do - switch off this light bulb, don't drive on that journey, don't build that factory. It's the government's responsibility to maintain the environment in a sustainable way and implement policies to do so. If it's not doing so, or worse not even trying to do so or doing so in a willfully negligent manner, then it should be held accountable for that. The same should be true of any of the government's responsibilities.
This is what's wrong. The government is supposed to be the people. The point of government is for people to steer people (as a collective) in the right direction.
I don't have the answers and, luckily, I am not a policy maker or <hardware maker> would be fined for deprecating 2 year old equipment, producers would account for the residual effects of their products' existence after it's usefulness expired, etc..
Now everyone run out and get in that Black Friday line to binge buy all those new XYZs, they're so much newer than the last iterations!
- they at least have a part in it. Just take your 'people who decide to use cars' argument: in countries like Belgium where it is, simply explained, more economical for a company to lease cars and give them to employees than to give the employees more loan. You can imagine what an employee does with a car he/she often doesn't even have to pay the gas for.
- they should be part of the solution as well. In my opinion it's their job to create a system where information and education about any of the problems you mention is available, or no, mandatory, for everyone annd definitely children. Teach them to do right, instead of having them believe chasing glamour or so is what's needed in life.
The US is a uniquely litigious country so going through the court system in an adversarial sense makes perfect sense. In The UK system you might instead ask a court to determine who or which state organ has responsibility to fix the problem or who has authority to do something. See for instance the judgement on the Brexit case: https://www.judiciary.gov.uk/wp-content/uploads/2016/11/judg....
It's not the only solution, and government didn't create it. People are causing global warming, not government. It's people who decide to use cars and get stuck in traffic instead taking a bus, bus will go that route anyway, people in cars will cause more traffic and generate more pollution.
People who don't turn off lights (also TVs, computers) at their homes over night. I met a lot of them, one of the dumbest excuse was... light bulbs break if we turn on and off the lights frequently, so they were leaving 3x 100W lightbulbs overnight, irony, they were working as council of Greenest Capital of Europe :)))
People who burn coal and wood to heat homes, burn coal = more CO2, burn wood = less forests.
People who don't recycle stuff - I'll just throw away that TV on a street or drop from 2nd flow window for fun! Ha! People who buy new phones and computers because that's a new fashion.
People who eat food that was grown in places were 10years ago we could see amazon rainforests.
People are too lazy and it's too hard for masses to leave their comfort zones.
