It is said that in the year 2050, the human population of Earth will reach 9 billion souls and then level out.
It is also said by the human haters that amount of people will start killing Mother Gaia and it would be better for mankind to participate in a massive die-off.
Well, I’m sure that there is a possibility of a Malthusian Event, but not right away.
The main reason I’m saying this is because of far-seeing folks who are trying to prevent such things with a little geo-engineering:
Science Magazine has removed the pay wall from “Food Security: The Challenge of Feeding 9 Billion People.” The paper concludes, as many have before, that keeping up with humanity’s needs as numbers and appetites crest toward mid-century poses big challenges. But it expresses optimism that a sustained focus on efficiency, technology and policy innovations can do the trick. (The images above, from the paper, show how investments in water storage and other measures helped restore vegetation in a dry region in Niger.) Here’s the summary:
Continuing population and consumption growth will mean that the global demand for food will increase for at least another 40 years. Growing competition for land, water, and energy, in addition to the overexploitation of fisheries, will affect our ability to produce food, as will the urgent requirement to reduce the impact of the food system on the environment. The effects of climate change are a further threat. But the world can produce more food and can ensure that it is used more efficiently and equitably. A multifaceted and linked global strategy is needed to ensure sustainable and equitable food security, different components of which are explored here.
The authors include a menu of possible uses for genetically modified crops, but stress that technology alone is far from sufficient if policies are not shifted to advance the appropriate use of the right agricultural strategy or tool in the right place. Over all, a focus on “sustainable intensification” of production of crops and livestock will be vital to limiting impacts on remaining undeveloped ecosystems.
Aquaculture holds great promise, if practiced appropriately and efficiently, as does livestock production, the authors say, noting the reality that meat will long remain a part of most diets, particularly in populations moving out of poverty.
In the end, they say, one reality has to be a shift from simply boosting production to a new, interdisciplinary focus on getting the most food value with the least loss of land and other resources. The kicker?
[W]e must avoid the temptation to further sacrifice Earth’s already hugely depleted biodiversity for easy gains in food production, not only because biodiversity provides many of the public goods on which mankind relies but also because we do not have the right to deprive future generations of its economic and cultural benefits. Together, these challenges amount to a perfect storm.
Navigating the storm will require a revolution in the social and natural sciences concerned with food production, as well as a breaking down of barriers between fields. The goal is no longer simply to maximize productivity, but to optimize across a far more complex landscape of production, environmental, and social justice outcomes.
Hydro-engineering in Africa?
Not a bad idea. And not a new one either.
In fact, it’s about one hundred years old. All it needs is a little more technology; http://strangemaps.wordpress.com/2008/06/08/287-dam-you-mediterranean-the-atlantropa-project/
The search for life on the planet Mars has been ongoing for about 130 years and samples of such have been lacking.
Now with the many satellites that are orbiting and photographing the Martian surface 24 / 7, evidence seems to be coming, but as the lid on such truths are maintained by NASA (for what ever reasons), speculation as usual runs wild.
Below however are some photos taken by the Mars Express probe around the year 2000 showing interpretive evidence of water in craters and forests around them.
Interpret them for yourselves.
I don’t know. NASA always claims that if they had evidence of ET life of any kind, they would be the first to proclaim it from the roof-tops.
They can’t prove it by me.
How about you?
