Bonsoir,
Je te donnes un exemple de début de discours qui j’espère te donneront des idées !
“ Our planet is facing many problems and one of them being pollution. Everything we do as humans can have a consequence : using technology, throwing plastic on the floor and even driving can increase pollution. This is why we have around us many other ways to dislocate such as buses, subways and many more ! Using these will help our Mother Nature even though transports take up much space in the streets”
voilà ! :)
