I have started taking a course about sustainability (https://www.coursera.org/learn/sustainability/), just in case I can learn some new things, which I can use on my page about ending the destruction of our habitat (http://archania.org/ending_the_destruction_of_our_habitat.html).
So far, I have learned about an equation which I am going to write a little about:
And I have found a nice graph which shows the decrease in global fisheries:
More might come here, if I discover more useful information.

There's too much at play here to simply draw that conclusion. This could go hundreds of ways.

We did. You did. Yes we can. No.

Tea may be inefficient per kg of tea leaf, but how inefficient is it per kg of actual tea? Most foods aren't judged by their dessicated weight. Similarly though to a lesser extent for coffee.

You should also take into account that there will be less and less farmland due to buildings and most importantly, global warming.
This is often overlooked, but the destert areas near the equator will see temperature increases in such a way that we will lose a lot of farmland.

Why will we get more urbanisation while transportation gets faster and cheaper?

You are using the wrong metrics there. It is logical that the rural population decreases, because farms get bigger and bigger and the people working them get less and less, due to industrialisation.
Any rural area resident should see this.
Also, the city that I live in was the 'epicenter' of the biggest pig flu in hisory. Many pig farmers were forced to cremate their pigs and sell their companies.
Currently in that aspect we also see 'pig-flats' by the way, which house more pigs per square meter (on the ground) than ever before.

There are also graphs which countries use the most global hectares per person.
Could we tax the hell out of them or have global trade bans for those countries to improved the world?
