A few years back I had 17 or 18 60ft poplar trees cut down because of disease. 
If we go into a climate meltdown it will be all my fault..............in common with those who insist on driving a planet-killing derv car. 
A drop in the ocean with all your other considerable forest land surely

when I moved in to this house I chopped down ALL the trees ,bloody 30' plus conifers

a few doors down,someone has 40+ foot conifers right next to the footpath
the roots of which have destroyed the pavement ,
I think one day they will come down ,just hope non of our cars are in the way when they do

if they do, I guess it's my insurance that has to pay out ?
I have now got an ash tree ,doing quite well, next year I will plant more but keep them manageable ,
so I'm not anti trees ,just think people should think before planting ,maintain them
At the end of my garden is a field divided into allotments. One of the allotment holders planted a Eucalyptus tree, of all things, just the other side of my fence just before we moved in 15 years ago. The bloody thing is 30 feet high now and growing so fast you can almost watch it.
The knobs in charge of the allotments promised to cut it down four years ago, but still haven't done so, and have a long list of excuses for themselves. The latest one being that they cant afford it, and they feel that I should pay for it. Im willing to fell it myself, onto the middle of the allotments obviously, but swmbo doesn't want the ensuing hassle.
I might just look into the cost involved, and if its not a silly amount, have it done just to get rid of the bloody eyesore.
I empathize , I'd happily cut the crappy local conifers down for free if the owner got rid of the rubbish
