technologies and is going to play a key role. John Bull, portrays 
himself as a creator of a museum experience. Dubai will host the 
Expo for 173 days in the name of ‘connecting the world and 
creating the future’.
The tale about the Sustainability Pavilion has its roots in life. Bull in one of his interviews said, "We don't say, ' let go your life and live in a cave, ' 

we realize 
we are living in this globe in 
Which we are confronted with difficulties

. So, we say, let's be wise,
 let's just take a few better choices to meet these difficulties''.
There are some wrong decisions we make together because we 
don't know. For example, I was surprised to find that an average 
cotton Tshirt was made with two and a half thousand 
Litres of water. It's a huge quantity, and yet we treat fashion as 
disposable.
People keep a T-shirt for one season and then get rid of it. This is not
a sensible choice. And when some of these layers of information or a shortage
of information explained through a good story,
It is evident that individuals love and want to safeguard the world
around them.
The magnitude of the crisis facing the planet is one of the difficulties
involved. It can make individuals feel helpless and uncertain about how they
can make a difference.
"Two sides to this coin, Bull suggests". Everyone can create a
difference. Every one of us can do tiny stuff in our life that will truly
create an impact. Expo 2020 Dubai is about bringing together individuals,
talking about stuff, finding ways forward. There's real hope if we can do that
and talk with a single voice to suggest a fresh path forward.
