I have learnt that..
1) Everyone is unique, they have their own strengths and weakness
2) In this community where everyone is different (race, religion, skin colour, beliefs), it is vital to embrace each other and accept them for who they are, for the community to stay together
3) Even though people are unique, they still have their similarities.
1) The activities
2) The 'embracing' part
I think that differences and diversity can be useful to our society as when we are in a crisis, different people will have different reactions, and some of them might be beneficial to the others. Diversity will also ensure that the Earth is not too boring.
