about plastic that has frag-
mented into microscopic
particles, but these make
up just 8% of plastic in the
gyre. Mr LeBreton reckons
that a leet of booms could,
by 2040, sweep up virtu-
ally all the non-tiny detri-
tus, but only if plastic leak-
age into the sea is stanched.
If it continues unabated,
the incoming debris would
outweigh the leet’s capacity to skim it
within a few years. The ocean’s plastic
problem cannot really be solved without
better waste management on land. l

current alone. It therefore scoops the lit-

nautical miles off the coast of California
for a fortnight of tests, before embarking
on a three-week voyage to its inal destina-

with its ends fastened in place using met-
al lines, and set adrift. Satellite tracking
and other electronics will allow its progress
