Though
some
beaches
form
on
inland
freshwater
locations
such
as
lakes
and
rivers,
most
beaches
are
in
coastal
areas
where
wave
or
current
action
deposits
and
reworks
sediments.
Erosion
and
changing
of
beach
geologies
happens
through
natural
processes,
like
wave
action
and
extreme
weather
events.
Where
wind
conditions
are
correct,
beaches
can
be
backed
by
coastal
dunes
which
offer
protection
and
regeneration
for
the
beach.
However,
these
natural
forces
have
become
more
extreme
due
to
climate
change,
permanently
altering
beaches
at
very
rapid
rates.
Some
estimates
describe
as
much
as
50
percent
of
the
earth's
sandy
beaches
disappearing
by
2100
due
to
climate-change
driven
sea
level
rise.[1]
Sandy
beaches
occupy
about
one
third
of
global
coastlines.[1]
These
beaches
are
popular
for
recreation,
playing
important
economic
and
cultural
rolesβoften
driving
local
tourism
industries.
To
support
these
uses,
some
beaches
have
human-made
infrastructure,
such
as
lifeguard
posts,
changing
rooms,
showers,
shacks
and
bars.
They
may
also
have
hospitality
venues
(such
as
resorts,
camps,
hotels,
and
restaurants)
nearby
or
housing,
both
for
permanent
and
seasonal
residents.
