SALT FROM THE SEA
Salt is essential for life and has been
traded here for centuries. People around
the Indian Ocean make salt by flooding
large, flat areas with sea water. As the
water evaporates in the sun, salt crystals
are left behind. These are then collected,
drained, and cleaned.

MANGROVES
A lot of the coast in the tropical part
of the Indian Ocean is fringed with
mangrove forests. These amazing
trees live in brackish water and
have long roots that trap sediment
and protect the coast from erosion.
Without these trees, settlements
and land along the coast are in
danger of being damaged by
high tides and strong storms.
The moutia
dance of the
Seychelles was
brought to the
islands by
African slaves
in the 1700s.
INTERNATIONAL SEAWAYS
The Indian Ocean contains some of the busiest and
most important shipping routes in the world. Smaller
ships sail to and from the Mediterranean Sea and the ports
of Europe and America through the Red Sea and Suez Canal,
while larger freighters and oil tankers from the Persian Gulf sail
around the Cape of Good Hope at the southern tip of Africa.
