Very interesting discussion everyone, thank you all for the time you’ve put into articulating your thoughts.
I’m afraid I might not have much to contribute but I did want to pick up on the point about current population levels being unsustainable, and that suffering and death of millions (billions?) was inevitable.
Sure, the consumerist economy and all the products associated with it may not be able to be sustained at its current level, let alone at a level where all the world’s population has been elevated to the same standard of living, but necessities, particularly food, should be within our capabilities, without even needing to go vegan.
Firstly, I’m sure it has been stated many times that we could eliminate hunger already, if only the food would not be wasted and could be distributed fairly. But regardless of this fact…
Allon Savory is trying very hard to get people to adopt holistic practises when it comes to land management and the raising of livestock. His Savory Institute (
http://www.savoryinstitute.com/) uses grazing practices that are organized in a way that mimics nature, allowing for huge herds that actually help the depleted grasslands replenish and thrive, (reversing desertification), and be capable of sustaining much more biomass and livestock than current farming practices allow, and even altering the ecology of the landscape to retain water better and develop year round streams and wetlands. If these techniques are adopted worldwide, the restoration of so much land to good agricultural land capable of sustaining huge numbers of livestock as well as providing opportunities for holistic crop and vegetable growing, would be an incredible boost to our food growing capacity.
Perhaps more importantly, it would also serve to sequester a huge amount of carbon, not just in the biomass of the new plants and animals supported, but in the continued enrichment and growth of the soil.
Another kind of projects coming at the food problem from the technology angle are vertical farming and the Sahara Forest Project (
http://saharaforestproject.com/). Vertical farms could be built on a grand scale in or near cities by the hundred, making the cities practically self-sufficient for food. The Sahara Forest Project has demonstrated that using only sunlight and saltwater, they can grow food, make drinking water, renewable electricity and biofuels as a profitable enterprise in the desert. If this was scaled up and seawater pipeline infrastructure developed huge areas of desert could be turned to useful food production with a potentially negative carbon footprint.
Both of these technological approaches would require a huge investment, but if it’s profitable then it could happen, or a strong government could make it happen anyway if it was needed. Eitherway, it is possible.
Then if we also stop using fertile land to grow crops used for livestock feed (no longer necessary with the holistic approach) or biofuel, we would have even more arable land to put to use feeding humans.
All together, the food production capacity of this planet could be massively increased.
Biofuels will soon be able to replace petrol and even jet-fuel, and will be able to be made from algae bio-fuel plants using only brownfield sites and saltwater.
Plastics will likewise be able to be made from algae.
3D printing will make most international shipping unnecessary.
Electricity can of course be wholly renewable.
We could build and build (tech-farms, algae-farms, renewable power), and be able to sustain an ever increasing number of people, without increasing our geographical footprint, and in fact even letting the amazon and other devastated ecosystems regenerate and return to the natural state and original size.
We are only limited by the actual raw materials on the planet, namely carbon, hydrogen and oxygen.
The technologies we need to facilitate our modern way of life and standard of living for the whole human race are already here or very nearly. We only need for there to be a concerted effort to make these become our dominant technologies and methods. This could even be purely market driven, with government incentives or a carbon tax, or simple consumer choice, after all, these technologies are going to be cost competitive soon, and a good investment for forward thinking companies.
What I’m trying to say is this, we can feed the planet and elevate standard of living for everyone, sustainably and without sacrificing diet or lifestyle. And we could even combat climate change at the same time. This could be achieved without a massive collapse and within the current capitalist framework. Or it could be forced through strong government action.
Whether or not we’ll ever even start on that path is another matter. Even though the technology is within reach, the political will to take hold of it may never materialise in time. We could well see global food crises and famine and civil unrest and government crackdowns all over the world, and the kind of collapse you have been talking about. But it’s not the only possibility.
So, I am optimistic that the technological solutions are at hand. I am pessimistic that they will be adopted with any speed. But I am optimistic that they will win out in the end due to basic market forces, despite efforts from the vested interests. Only a few industries would crash. The governments and economies would survive intact (unfortunately) but a collapse will have been avoided and mankind can proceed into a clean, renewable, sustainable future. Not some backward carrot-growing pre-industrial feudal existence. So I think I could live with that.
