Andrew Hansen: When I moved to Melbourne, I thought, "At last!
00:03
"Good coffee, great culture,
00:04
"really great intellectual conversations
00:06
"about the weather."
00:08
Because we do that here, don't we?
00:09
We talk about the rain, the cold, the heat,
00:11
all the weather types.
00:13
Well, maybe it's because this city of ours
00:15
has relied on the weather for our water supply.
00:19
If there was enough rain, we were OK.
00:21
But if not, well,
00:22
tighter and tighter water restrictions
00:24
while we looked to the skies.
00:26
We can't rely on rain anymore.
00:28
Worldwide water conservation
00:30
is one of the biggest issues of our time.
00:32
First big challenge is climate change.
00:35
That means it's raining less,
00:37
and when it does rain, our land is drier,
00:40
so it soaks up more water,
00:42
leaving less to flow through to the dams.
00:44
Climate change also makes bushfires more likely.
00:46
Now, they threaten nearby dams
00:48
and take water to put out.
00:50
Then there's the fact that
00:52
everyone wants to live in Melbourne,
00:53
including babies!
00:55
Selfish babies!
00:57
So, everyone wants to join us
00:59
in Australia's fastest growing city.
01:01
And what do more people need?
01:03
More...coffee.
01:05
Which means more water.
01:07
Now, the good news is, we have a plan.
01:10
It's underway
01:12
and, breaking news, it's not all about the weather.
01:14
Instead, it's all about diversification.
01:17
Now, that means more stormwater
01:19
and recycled water,
01:20
you know, for non-drinking uses.
01:22
Means things like green roofs, raingardens
01:25
and plumbing that's clever
01:27
and not at all selfish,
01:29
like babies.
01:30
It means using desalinated water.
01:32
And it means everyone doing their bit.
01:34
Now, we only need to save this much water each day
01:36
to make a difference.
01:38
Chances are...we can do this by asking ourselves
01:42
the big questions.
01:43
Questions like...
01:45
Do you turn the tap off when brushing your teeth?
01:47
Can you get out of the shower a minute earlier?
01:50
If it's yellow...
01:52
..do you let it mellow?
01:55
Now, there's a conversation to replace the weather.
01:58
But the bigger conversation
02:00
and the one we all need to have
02:02
is about conserving water.
02:04
I'm talking reaching our daily target
02:06
of 155 litres per person per day or less.
