Population, agriculture and energy: Are we killing the earth?

What is the future of earth?futureearth

As the world’s population grows, the already depleted natural resources are reduced further. As citizens of the planet, we are the only ones who can change how we live in order to make the way we live sustainable. Continuing to consume like we are does not seem sustainable without new innovations being created.

In the 1960s the planet reached what the scientists said was the max capacity of human beings at 3 billion. We were told this was the optimal number of people for earth to sustain. We are now at 7.4 billion with projections of around 8.9 billion by 2050. In order for this enormous population to survive, we had to adapt. What is known as the Green Revolution occurred.

We began monoculture, created fertilizer and pesticides, dwarf crops, irrigation and genetically modified crops in order to produce enough food to feed the world. These practices have impacted the earth negatively in a number of ways. Water systems have been affected by either being diverted or polluted by agriculture. In addition, farms on such a scale have diminished biodiversity and have damaged ecosystems. Agriculture is just one aspect of the consumption that occurs around the globe. Since food is kind of important to us, how we grow that food should be as well.

Food is not the only resource we are consuming. Energy consumption is another issue as standards of living in nations around the globe continue to rise. This energy currently comes mostly from a nonrenewable source: fossil fuels.

A green push for Asia (AlertNet)

As Asian growth slows, a green push could pay – experts

By Chelsea Diana

LONDON (AlertNet) – As Asia moves away from export-led growth, the need to invest in green growth instead is key, panelists said at an Overseas Development Institute-held discussion.

But, who is green growth for and what implications does it have for both the public and private sector?

The answer is complicated, with some seeing “inclusive” green growth as a way to reduce poverty, while others see poverty reduction as the eventual result of an improved and more resilient economy.

ASIA IN CRISIS

Global financial crises have had a major impact on Asia, which has seen declines in exports and GDP growth. Masahiro Kawai, chief executive of the Asia Development Bank Institute, said inclusive green growth could help.

To cope with changing conditions, inter-regional trade has become more common in Asia, in particular incorporating developing countries such as India and Cambodia into supply chains.

With more countries involved in regional trade, green growth, specifically low-carbon growth, will be key to ensuring environmental stability, improvement of human health and pollution reductions, he said.

GREEN ECONOMICS

With environmental degradation and climate change making big impacts on the continent, one solution is to focus on the three pillars of green growth: environmental, economic and social, said Alex Bowen, a green growth research fellow at the London School of Economics and Political Sciences.

World hunger has no single, easily discernible source, least of all overpopulation (ACF)

Hunger and Population Growth: Correcting a Common Misunderstanding

As the media report that the world’s population is expected to top 7 billion by the end of October, the subject of global hunger is bound to arise, as is a commonly held assumption about global hunger: “There’s so much hunger because the world is overpopulated.”

Like so many hypotheses, the perceived relationship between hunger and population rests on a seemingly logical premise: the world can produce only so much food, so if people are going hungry it must mean too many people exist.

But this isn’t true. In fact, evidence contradicting this line of thinking is widely available, but all the evidence in the world won’t make any difference unless others like you know it—and use it as well.

To begin debunking the overpopulation myth, it’s worth exploring the relationship between world population and childhood malnutrition. (Our data is from the World Bank’s World Development Indicators.)

Between 2000 and 2009 (the last year of the data), the world’s population went from 6.085 billion to 6.775 billion. In other words, it increased by about 11.3 percent. The growth was not uniform; the highest rates tended to occur in so-called “developing countries” where per capita income is low. These are largely the same countries where hunger and malnutrition are at their worst.

Given all this, those studying the data might expect childhood malnutrition increased at least as rapidly as world population over the same period. Actually, the opposite took place.

Seven billion people and shrinking?

Posted By Colum Lynch

Sometime around Halloween, the United Nations will celebrate the birth of the world’s 7th billion baby. As U.N. Secretary General Ban Ki-moon told world leaders in New York last month, the 7th billion baby will most likely be poor and will inhabit an earth buffeted by the ravages of global warming, desertification, and dwindling food shortages.

Sounds swell. Given this kind of apocalyptic rhetoric, it’s no surprise that much of the media’s focus has been on the strain of an over-populated planet, one where more than 79 million people are added each year to the human family, overwhelming already overcrowded cities, fighting it out over a dwindling pool of natural resources.

But what if the world’s population actually shrank?

Earth reaches 7 billion mark; planet overpopulated, strained

Jake Buffenbarger

The world did not end Friday, nor will 2012 bring about fire and brimstone, like so many claim it will. However, there are threats to the human race not being talked about by religious fanatics but instead by educated men of science.

By the end of the month, the world’s population will reach an astonishing 7 billion people, according to estimates by the United Nations.

In the past 100 years humans have experienced unprecedented exponential population growth due to advances in food production and distribution, according to Yale.edu.

Although the abundance of people may seem like a blessing, it is in fact a threat to our species as a whole.

Resources are already strained enough as it is with the current population.

Generally, developing countries have much higher growth and death rates than developed countries. Countries that have low child survival rates do so because of a lack of modern medicine, family planning and a natural human tendency to not put all of our eggs in one basket evolutionally. Due to the hardwiring of human brains, adults in countries with high child mortality rates make up for the potential loss of their young by having multiple offspring. This gives them a better shot at passing on their unique genetic code, which is the primary objective of all life.

The global population will grow to a staggering 9 billion by 2050, according to a 2009 United Nations press release.

The world’s biggest problem? Too many people

Our unsustainable population levels are depleting resources and denying a decent future to our descendants. We must stop the denial.

By Mary Ellen Harte and Anne EhrlichJuly 21, 2011

Think back on what you talked about with friends and family at your last gathering. The latest game of your favorite team? “American Idol”? An addictive hobby? The new movie blockbuster? In a serious moment, maybe job prospects, Afghanistan, the economic mess? We live in an information-drenched environment, one in which sports and favorite programs are just a click away. And the ease with which we can do this allows us to focus on mostly comforting subjects that divert our attention from increasingly real, long-term problems.

………………….

Overpopulation is also fueling desertification and further deforestation around the world. We can dream of drastically decreasing overconsumption by the wealthy, but even realistic potential decreases are voided by sheer human numbers in all countries, rich and poor. Our unsustainable population levels are depleting resources and denying a decent future to our descendants.

What to do? Stop the denial. Perpetual growth is the creed of a cancer cell, not a sustainable human society.
