lake ecosystems
that can’t support
full biological
diversity any more

acid rain, and many
others.

10. What can we do to

throw down your sink.

household cleaning agents
and toiletries.

11. CONCLUSION
I think that we have
to change our habits
because the water is a
natural resource very
important and if we
follow the same way
till now, one day
maybe our next
generation woke up
and they won´t have
water to drink.

12. Planting more trees can
also prevent water pollution
by reducing soil erosion and
water runoff i think that
educating people about
water pollution is an
important way of
preventing water pollution.
