Harry Styles spoke on a video released to fans today, stating “Over the years, you’ve shown us what you can achieve when you rally together. At two historic summits in September and December, world leaders will make decisions that affect important human issues such as extreme poverty, inequality and climate change.”

Louis Tomlinson then added “Now is the time for us all to have our say – to take action and to raise our voices to show that we care. We can be part of something that actually makes a difference to our future, and helps people who need the support.”

Liam finished off by saying “All you need to do is tell us what you want your world to look like in the future. You can make videos or send us pictures, it’s easy. Just complete one of the actions listed on our site.”
