A Quote by Tony Blair
When my parents were growing up the world's population was under three billion. During my children's lifetime, it is likely to exceed nine billion. You don't need to be an expert to realise that sustainable development is going to become the greatest challenge we face this century

When I was born, the world's population was 3.5 billion. There are now 6.8 billion people on the planet. By 2050, that's expected to rise to 9.4 billion. What's more, the Earth's resources aren't growing; they're decreasing - and rapidly.
Planet Earth is estimated to have a lifetime of nine billion years. And we're right smack in the middle of our lifetime. We've been in the universe for 4.5 billion years. So, that should mean something. We should sort of take a look at where we came from and where we are going.
I always give the analogy of the Earth at Night picture, of 7.3 billion of us, right? And everyone says, "Well, that's population." Well, if you took the entire world's population and you lived at the density of Manhattan proper - not a bad place to live - how much space do 7.3 billion people take up? The state of Colorado. At which point I end my lectures, because I want you to be thinking ... is this really a question of population, or is this a question of land use and resource consumption? And let's face it, the top 1.3 billion of us are doing all the damage. Sorry.
The bigger question is how does a rogue species called humans - whose population just blew through the seven billion mark on it's way to nine billion members - manage to survive the next century on a planet with finite resources, without destroying its delicate balance in the process.
At the beginning of the 20th century, there were less than 3 billion people on the earth, closer to 2 billion. By all measures that we can come up with right now,. with the lifestyle and consumption pattern of the Western industrial civilization, we can probably sustain about 2 billion people on this earth. We already have over 6 billion. China and India are aspiring to come on as industrial nations, aspiring to the lifestyle of the Western world, and it simply can't happen.
Given that my title at Google is Chief Internet Evangelist, I feel like there is this great challenge before me because we have three billion users, and there are seven billion people in the world.
If we could magically transport ourselves back to the young Earth, when it was only a billion years old or two billion years old or three billion years old or four billion years old, we wouldn't be able to survive. We would have a hard time surviving if we were transported to the time when dinosaurs were around.
The number of children in the world is not growing, and so we eventually have a chance to stabilize the population at around 10 billion. We have the technology and wherewithal to feed and provide energy for this many people.
If you can't figure out how to make money on three billion in revenue, when exactly will the profit magic be found? Ten billion? Fifty billion?
Today, if you look at financial systems around the globe, more than half the population of the world - out of six billion people, more than three billion - do not qualify to take out a loan from a bank. This is a shame.
A father and two sons run Adelphia. It's a cable company. And they took from that company a billion dollars. A billion. Three people - three people took a billion dollars. What were they gonna do, start their own space program? 'Let's send the monkey to Mars, Dad!'
The wealthiest 300 people have greater riches than the three billion poorest. The three wealthiest people have greater riches than the 48 poorest countries put together. With only limited environmental space to accommodate the expected 9 billion human inhabitants of the world by 2050, such disparities in consumption are clearly not sustainable
I meet so many that think population growth is a major problem in regard to climate change. But the number of children born per year in the world has stopped growing since 1990. The total number of children below 15 years of age in the world are now relatively stable around 2 billion.
I know one thing: There are a billion Islamic people in the world today, and there will be about 2 billion by the time we're dead. They're not going to give up their religion.
