Systems Analysis and Design: Population and Sustainability Essay

This essay, prepared for a Systems Analysis and Design course, delves into the critical issues of population and sustainability. It examines the views of various experts on overpopulation, carrying capacity, and the environmental impact of a growing global population. The essay explores the challenges of feeding a projected 9 billion people by 2050, discussing potential solutions such as increased food production, efficient food preservation methods, and the role of technology. It also analyzes the benefits and drawbacks of population growth, including genetic diversity, and addresses the impact of industrialization on the Earth's atmosphere and resources. The essay references scientific data and expert opinions to provide a comprehensive overview of the complex relationship between population, environmental sustainability, and resource management, emphasizing the need for global cooperation and innovative solutions to ensure a sustainable future. The essay argues that while overpopulation poses significant challenges, advancements in technology and food production offer hope for managing these issues effectively.

David Attenborough states that the world is facing many environmental problems. If
humans are unable to reduce the population, every problem dealing with overpopulation will
be more difficult and almost impossible to solve. According to Sean Lanahan, people are
producing enough food that can feed double the current world population based on
technology and land availability. The term "Overpopulation" or the myth of
"Unsustainability" is created and design to control the human population, and this is the main
reason for euthanasia and abortion. According to Charles Mann, currently, the world has 7.6
billion people. And most of the scientist believe that within the 2050 year total population
will be 10 billion. Within this time, humans will be in "replacement level," which means a
couple will have enough children to replace themselves.
According to statics, if control measures for the growth of the world's population are
implemented today, the effects of those measures will begin to come to fruition by 2100. But
few people agree or pay much mind to it. According to them, it would destroy the human
race. They cant see that population growth is affecting the Earth/environment as well as
space. Due to industrialization, the Earth's atmosphere is changing drastically. Oceans are
polluted, and The Earth is warming. Effects that may, at some point, be irreversible.
Controlling the human population is, in my opinion, a way that we can improve the carrying
capacity here on Earth.

Introduction
This essay can produce different views on population and sustainability. In the essay
concept of carrying capacity, the possible outcomes of a growing population, benefits, and
drawbacks of reducing the population and the methods of producing enough food for 9 billion
people are discussed.
Within just the last few years, technology and science have enhanced human
capabilities and population size. Carrying capacity is an ecological concept that can define a
relationship between the natural environment and a population on which it depends on
current sustenance. It can assume the total number of individuals. This is how carrying
capacity offers long-term sustainability (Barro,2017). The meaning of carrying capacity in
the current context addresses the humans who actually can support without humiliating the
cultural, social, and natural environment. Enhancing the human carrying capacity can harm
the environment's ability to sustain the quality of life. In today's society, we are entirely
independent of each other. The importance of Carrying capacity has excellent relevance when
it comes to the local community because carrying capacity cannot affect the local community.
The communities that are fighting with an opponent it is more likely to cooperate inside.
At the rate of population growth, humans are already used 1½ earth’s resources. The
demand for Earth’s resources and space is increasing day by day because of population
growth (Barro, 2017). Many countries in this world are weak in illiteracy, sanitation, poverty,
decreasing natural resources, and poor waste management. The population growth rate is not
the same in every country. Advanced countries like Japan and few countries in Europe are
growing comparatively slower than other countries. Other industrialized countries like the
United States, Australia, New Zealand, Argentina, and Canada are increasing their

populations in 30 to 40 years. If every people around the world start working together, they
can discover new ideas.
One of the main advantages of the growing population is it can provide genetic
diversity. The term “genetic diversity” means humans have a better chance of surviving from
any disaster or disease. If most of the people contain the same genetic weaknesses or
capabilities, then a specific disease can kill one person and that one person can kill everyone
else, so having a massive set of genetic factors is helpful for survival. Diversity is also a big
advantage in economically and socially (Barro, 2017). Communications of a different group
of people in the society can bring happiness. Population growth is draining resources,
healthcare, food, and clean water slowly. People are cutting down rainforests and polluting
the atmosphere. In many countries, people are struggling with clean water.
The earth population will be 9 billion within the next 33 years. That is a huge amount
of people to feed. That is the main reason of the hunger issue in most countries. But the good
news is humans are producing enough food to feed most of the people around the world. To
feed 9 billion people, we need to increase food production within 2050 (Barro, 2017).
Another useful method of feeding 9 billion people is keeping the food fresh. Most advanced
countries in the world use the "cold chain” system to save food. However, few countries are
lacking this system.
