With
the
rise
of
online
food
delivery
services
in
China,
the
past
few
years
have
witnessed
an
alarming
increase
in
packaging
waste.
According
to
the
bar
chart,
China
contributed
0.18
million
tons
of
packaging
waste
in
2015,
and
by
the
year
2017
it
had
multiplied
almost
nine
times
to
1.6
million
tons.
This
figure
nearly
doubled
in
the
following
year.
Food
packaging
usually
consists
of
single-use
plastics
including
containers,
tableware
and
plastic
bags.
As
is
known,
marine
plastic
pollution
poses
a
major
threat
to
coastal
ecosystem.
Scientists
worry
if
the
packaging
waste
continues
to
grow
at
the
current
rate,
many
marine
species
will
become
extinct
in
the
future.
By
turning
to
recyclable
packaging
materials
and
reducing
the
use
of
disposable
chopsticks
and
spoons,
we
are
saving
the
future
of
human
race
to
a
large
extent.
