As humans do, some smart scientists hit upon the idea of GM foods. Perhaps not intended for this use, but damn useful nevertheless. So, you think we would at least have started to solve half of the problem. GM allows for crops to be grown in different climates, produce more productive harvests, become less susceptible to diseases. However, this isn't the case. Because now we get protests about GM.
Now, I do try to look at all the possibilities when I look at these issues. But really, if you test well enough, and only make small changes, there is virtually no risk for GM. Putting one potato's genes into another potato is hardly going to make a killer carrot.
But what does get me about this situation is that a large proportion of people who are against GM foods are all for the right of the "unborn child" to the extent where they do not accept that we have an overpopulation issue. Come on guys, surely you can see that there's an issue here. Cities becoming more crowded, more squatter camps everywhere. The people in poorer countries across Africa multiplying like rabbits. And there simply isn't the food to feed them, if you don't use GM, because there isn't the land to feed them.
This is where that little splash of global warming comes in. Taking the average estimate that the world will warm by about 4 degrees, we actually have a lot more to worry about than a bit of low-lying land being lost. Because, with higher temperatures around the equator, Africa will become uninhabitable. Europe will mostly become uninhabitable. the US, China, Mexico, most of Brazil, all uninhabitable. The land that you gain will be Norway, Canada, Russia&Siberia, Antarctica, parts of Australia and parts of pacific islands around NZ's area becoming more habitable. Now, have a look at the below map:

Green is habitable. Yellow is desert, brown is floods, drought or extreme weather. Red is land lost due to rise in sea level.
So, can you see how much less land there is available? Remember that anything at the top or bottom of the map is stretched. So, less land for food growth, and time needed to get it all started.
Here we now have a triple-whammy: Global warming, no more surplus food, no more surplus land. It's simply not going to work unless we do one of two things:
- Control population
- Use GM to our advantage.
If you want organic food, you must have less population. If you want more population, you must have GM food. To me, at least, it's that simple.
