Some interesting points and questionable attitude.
@Guinnless your post reads as both bitter and selfish.
Single use plastics are certainly a major problem, whilst I try my best to reduce the amount we use by shopping in refill shops, butcher puts the meat into my own plastic boxes, fruit and veg bought loose and put into reusable net or hessian bags, soap instead of shower gel or shampoo, etc, there's a few items, Toothpaste and deodorant, that I cannot find a 'green' alternative that works sufficiently.
Clothes I wear until they have holes in and then they either go to recycling or I use them as polishing and cleaning cloth in the garage.
We will be moving house in a few weeks, an older house, it's getting new windows with a high efficiency, an upgrade to the loft insulation, a split high temp air source heat pump, new cast alloy rads and an electric cast iron range, two "modern' eco wood burners (about 85% efficiency) and perhaps most importantly solar panels and batteries to augment the supply of power we require. No more coal, oil or gas being burnt on the premises. The woodburners will most likely only be used in the winter months and are really more of a luxury than a necessity.
Whilst I realise all of these things need to be manufactured and transported which produces a carbon footprint, I'm hoping this will greatly reduce our carbon footprint and be a more sound ecological and economic way to run our home as well as being warm, comfortable & draught free that will last 25 years +.
As for transport, my bike was built in 1950, it only really gets used for recreation in the summer months and we are seriously considering an electric vehicle for our next 4 wheeled transport as is my current employer.
When it comes to my hifi, I really only have time to use it for an hour or two the odd evening and a few hours on a Sunday and generally in the summer if the sun's out so am I. I think I can warrant to still use Class A amps if I so wish as they're my preference based on my experience and the excess heat is not wasted.
Whilst I don't have all the answers to increasing issues of climate change or plastic in our Oceans (I wish I did) I personally feel we all as individuals have a responsibility to do our bit.
As for waste, well it's just foolish.
