famine due to climate change

CLIMATE CHANGE CONSEQUENCES



Only a few people, without the theoretical background relevant to climate science, realise that on the long-term we bring ourselves in danger because we are with 6 billion people needing food and fresh (sweet) water to survive.
When the climate will change further, the glaciers up the mountains providing our rivers with fresh water will melt. Consequently in the short term there will be floods at the fertil river side, destroying the harvests. On the long run, the consequences are even worser: the river's water level is going to shrink and one day it shall be dry which is devastating for the harvests.




Furthermore we lose fertile landscapes by the increasing sea level, which also increases the amount of salt in the bottom, making it unable to grow most food species.

Of course only the change of the climate itself is enough to do the trick...

So climate change will undoubtly raise pressures on our available food supply while our population is still raising.

In an interview to new scientists, James Lovelock states:

"

I think it's wrong to assume we'll survive 2 °C of warming: there are already too many people on Earth. At 4 °C we could not survive with even one-tenth of our current population. The reason is we would not find enough food, unless we synthesised it. Because of this, the cull during this century is going to be huge, up to 90 per cent. The number of people remaining at the end of the century will probably be a billion or less. It has happened before: between the ice ages there were bottlenecks when there were only 2000 people left. It's happening again."

Further in the article he gives, thank god, solutions to prevent the worst from happening.

But, I think this foodproblems can be solved partly by the vertical way of farming I wrote about in my previous post.

And as 67% (!) of the world fresh water amount was used by agriculture in 2005, vertical farming may be a solution here too.
