From 2 billion to 7 billion and then...

In 1951, the year of my birth, there were 2,58 billion people.  Today it is 7.6 billion.  No wonder everything is crowded and resources are being used up.  I had wondered if I should have a more positive view towards the future, but this seems to say it all.  This many people today are not doing a good job of living 'with' the planet.  Can you imagine how much better or worse it will go with more people? The UN Intergovernmental Panel on Climate Change released their Climate Change report yesterday. It is what brought my attention to the population plight. That report gave 2030 as the defining year by which action must be taken. The well-used number for the maximum population that the earth can sustain is said to be 10 billion people.  It is based on food resources.  The common statement is that 2050 is the year that will happen. The statement goes:  "By 2050, the world’s population is expected to reach 9.1 billion, and the United Nations’ Food and Agriculture Organization (FAO) predicts that at that point, the world would need to produce 70% more food than today to feed all those people." This is considered contentious by the American Council on Science and Health.  They are pro-industry, but fact-based, and they think the 70% increase is an inflated number, along with the prediction discounting the advances in technology, and that it disregards the drops in population that are happening. The Economist says it is not time to panic yet - that the number of hungry people has fallen, that eliminating waste will raise food production by 60% or more, and so on. So the pros and cons for the maximum population are debated. Yet isn't that date looming near for those who will be alive in 2050? Anyone 18 years old today will be 50 years old then - perhaps just over half way through a typical lifespan.  And think of 2030 - those born in 2000 will only be 30 years old.  I wonder what our young people think of these urgent messages and concerns and how they will deal with them as the urgency grows. We are looking at the Sunnylea garden in an August rain.
