Not quite sure what my point is () but if every one if these 7.6 billion humans is also aspiring to a TV, fridge, a car and an easy jet flight to Benidorm every year.......then we’re doomed!

What you have not appreciated in this analysis is there is there are 1.5B cows in the world that produce ~100kg of CO a year, which is 23 times worst than CO2 on the atmosphere, that is equivalent to ~3.4B tons of CO2!! -> Kill the cows they are destroying our planet -> If you care become a vegetarian

(thanks Google, I trust you)

mmm...kill the cows....I’m seeing a medium rare rib......helping others become vegetarian

that is methane btw my inorganic chemistry is a bit rubbish CH4 i think

pass the horseradish

Always happier with a bit of C2H5OH

Balance that against the vast number of CO2 and methane producing animals we've killed, must be 70 million bison to start with.

At the moment we seem to be going through the world eating or pushing out every other species.

Started ages ago, over farming in the Fertile Crescent, cod nearly extinct off Newfoundland, peak oak in UK, dustbowls in USA.

We've been transforming this world for thousands of years.

But nothing remotely compares to the transformation over the last 100 years. The rate of change is totally mind-blowing. Had you been born in any other century you would have witnessed barely any local or global change over your lifetime. Now looking back even just a decade or two is a big step in technology. Basically, the global impact of humans was pretty insignificant for about the first million years and then it's suddenly gone totally ballistic in the last 100 years. It's not what you would call a linear progression and that's why it's so hard to predict the impact this sudden change will have on the planet. But you would have to say it's a totally unsustainable rate of change, especially when you start extrapolating thousands of years forward.

I get a lot of photos of Colchester and around. Since we've had photography the world has changed dramatically; and they're still building more houses as fast as possible.

Was sitting in my solicitors office a couple of years ago right in the centre of town, when first built it was a farmhouse surrounded by fields.

It all seems to have started going seriously wrong when we found cheap energy. Our lives have been fantastic on the whole since WW2 and now we're beginning to see the cost.
