Our knowledge about the health of living dolphin
populations is sadly incomplete. The grave danger is
that some unique and fascinated dolphin species will 【S1】______
be gone. Urgent action is needed to avoid the deaths of
hundreds of thousands of dolphins that accidentally 【S2】______
killed every year. Some years, the figure has surpassed
half a million worldwide—all because of human
activities. This is more than 10 time the number of large 【S3】______
whales that were slaughtered in the early 1930s, the
worst years of whaling.
Dolphins may be dying because of pollution
from dumping at sea, oil spills and farm pesticides and
other chemical runoff that enters the rivers, particularly 【S4】______
in the Mediterranean and off the east coast of the United
States. For some cases, food poisoning from red-tide 【S5】______
organisms may have been the cause.
It is not enough for humans to stop killing dolphins
and some other sea animals for food or other sources. 【S6】______
We must reserve a place for it in the sea. They 【S7】______
need habitat, as did all animals—places free from 【S8】______
fishing nets, oil spills, pollution and too many ship 【S9】______
traffic. We must also consider all the species in
the dolphins’ food chain. Which fish are the dolphins
eating? Which fish and other organisms are the
fish eating? To protest habitats, all these things must 【S10】______
be taken into account.
