Ecologists focus on the constraints to population growth.

Simon is essentially arguing that throughout history technological advances have made it so that natural resource and food production have more than kept up with population growth and demand. He also suggests that human impact on the environment is not as negative as some have claimed. These are important aspects of the IPAT equation: if more population, affluence, and technology do not bring resource scarcity and greater environmental impact, then the equation does not hold. Simon won his bet with Ehrlich (as described in the Wired Magazine reading), so there must be some substance to Simon’s ideas. He was certainly correct that in virtually all cases, natural resources and commodities like food are more plentiful now than in the past, and supply has certainly kept up with demand. What Simon does not mention, and what Ehrlich and his colleagues failed to realize, is that commodity prices are not merely a reflection of overall supply or scarcity. Consider the price of oil. Oil prices in 2016 reached record lows even though oil is absolutely a finite resource. Much of this is due to hydraulic fracturing technologies, which have temporarily increased supply, but at a potentially great environmental price. Thus, when looking at these debates, it is important for us to be able to analyze the evidence and the arguments for ourselves, so that we can avoid making the same mistakes as others may be making.

In the last two centuries, population has skyrocketed.

Then, a summary of Malthus' main ideas of the first two chapters of mentioned work follows.

Thomas Malthus with his book Essay on the Principle of Population.

This suggestion was unmistakably outrageous given the moralitiesof the times (and would doubtless be most controversialtoday).

The Essay on the Principle of Population and other writingsencouraged the first systematic demographic studies and also hada significant influence in several ways:-

In Economics David Ricardo's, "iron law of wages" and theoryof distribution of wealth contain some elements of Malthus'theory.

How can we deal with population growth in the present day.

In spite of this, an examination of the implications inherent in Malthus’ analysis is revealing of some basic assumptions he makes regarding the economic role of women....

A world population of 250 million at the time has now gone up to about 6 billion.

Malthusian Theory of Population

Malthus was an 18th century English economist and demographer from Wescott, Surrey, who became famous for his theory on population. According to Malthus in An Essay on the Principle of Population, while population typically grows exponentially (2, 4, 8, 16…), food supply only increases arithmetically (2, 4, 6, 8, 10…), therefore creating the conditions for food shortages in the future. He advocated, to avoid this, behaviour leading to a reduction in the birth rate. He was also concerned that population growth would increase the supply of labour and thus drive down wage rates.

Malthus attended Cambridge in 1784 and graduated four years later with honors in mathematics.

Voting procedures often have a very strong geographic component. This is perhaps seen most visibly in the practice of gerrymandering. To gerrymander is to create an electoral district that is in a strange geographic shape so as to achieve some desired result. Often the result is to keep incumbents in office or to diminish the power of certain segments of the population. It is named after a districting scheme devised by former Massachusetts governor Elbridge Gerry; the scheme included a district which looked like a salamander:

An Essay on the Principle of Population

Governance. The nature of both formal governments and informal governance in a population is another important factor. Governments can advance policies that reduce vulnerability. They can establish agencies tasked with reducing vulnerability, such as FEMA in the United States. They can support education and awareness efforts, as well as economic development to reduce poverty. Finally, they can foster social networks and empower individuals and communities to help themselves to prepare for and respond to hazards. Likewise, even without governments, communities can informally engage in many of these governance activities. Often the most vulnerable people are those who are politically marginalized because these people have less access to key resources and opportunities. One example of the role of government that we've seen already is the Myanmar government during Cyclone Nargis. This government is isolated from the international community and, thus, was not welcoming to international assistance in the aftermath of the cyclone. Compare that to Haiti after its 2010 earthquake. Haiti, like Myanmar, is a poor country, but it has positive and close relationships with the international community and thus readily welcomed international assistance in the aftermath of the earthquake. This assistance saved many lives and is helping Haiti rebuild.
