problems they had. Deforestation and bad
management of waste b (be) their main
concerns. As a result, they c (create) an
environmental group to look for solutions.
First, they d (research) information about
the people, their businesses and the impact
of their actions. Then, they e (organize) a
campaign to protect the rivers in their town.
They f (talk) to the local authorities
about prohibiting the industries from

dumping waste. They g (start) teaching
people about recycling methods and the
whole town h (sign) a petition to stop
the destruction of their forests. They i
(plant) more than 2,000 trees near the river.
Now people in our town j (be) happy
with the results. Liliana, a 15-year-old
student at La Paz School, said: ‘Now we
k (have) lots of trees around our
houses and parks; the rivers are clean; and
we understand that when people work
together to support a cause, the little things
that everyone l (do) can create big
changes.”
