This week, the assembly focus was on Earth hour. We talked to  the children about the environmental issues they already knew  about and about what is happening to the planet. We also  discussed what we can do to try to limit our environmental impact.  We discussed the need to work towards a more stable climate  where people and animals can thrive. Earth hour is on Saturday  evening between 8.30pm and 9.30pm where as many people as  possible are encouraged to switch off all their lights for an hour as  a sign of unity towards a common goal.
