  1.  @sporkeh90  We're throwing away ~1000 tons of mostly aluminium in the form or rocket stages. On a total of 2 billion tons of waste, that's tiny. Some low-hanging fruit: 20 million tons of tobacco which ends up as ash (and used 10 million ha of arable land). 3000 containers (at 20 tons each) go overboard on container ships each year. Rocket stage reuse is still a very new technology (8 years). It'll take a while for everyone to develop new rockets.
