1. Since more people is equivalent to more consumption, which
means that as the population rises, the Earth’s resources will also
deplete-how fast depends on the number of people it has to
accommodate. The negative effect of this ‘more consumption’ is that
it will lead to more deforestation and loss of biodiversity to
accommodate the needs of the population. (sciencing.com) Not to
mention the increase of waste and pollution that will both harm the
environment as well as the all types of life living in it. It will also affect
the economy and development as continuous, rapid growth of the
population will also add to the challenge of achieving social and
economic development, as the government will have to increase the
range of its investments and efforts to ensure its accomplishment. (un.org)
2. Population growth remains a major driving force behind environmental degradation
and threat to the sustainable use of natural resources, reducing its quality and
quantity by overexploitation, intensive farming, and land fragmentation. With this
rises the concern of scarcity of arable land resulting in shortened/removed fallow
periods, declining soil fertility, and farm income due to farm subdivision.

3. *Abundance is the measurement of population in a given area which is determined
by number of birth and death rates.
*Birth rates are ratio of live births in a given area which affect as an addition to the
population. (insee.fr)
*Death rate are ratio of deaths in a given area which affect, in contrary, as deduction
to the population. (oxford dictionary)
*Growth rates is the ratio of change of population size subtracting previous
population size to current population size. (who.int)
*Age structure is the proportions of individuals of different ages which tell us about
the population more in specific detail. (bio.libretexts.org)
~All of which are fundamental key properties of population which determines and
affects it.
4. Demographers use age structure to illustrate population trends such as birth and
death rates. This is because age structure allows for better prediction of population
growth (opentextbc.ca) as it reflects the proportions of individuals at various life
stage-a key indicator of population status. (sciencedirect.com)
5. Carrying capacity is the maximum number of species that the environment can
support without causing its destruction. It is determined by constraining variables
such as food, water, shelter, space, disease, predation, and climatic conditions.
When a population reaches its carrying capacity, resources become scarce that
encourages migration or mortality rates to rise, causing the population to decline until
it reaches a stable level. Understanding the ecosystem's limitations and
controlling the population are critical for achieving a sustainable environment.
However, it is only known to be applicable to species. (enviropaedia.com) As for
human population, some variables may not be equally distributed among them, with
some consuming more than others, and with the continuous global
advancements on the rise, human carrying capacity remains neither constant nor
easy to calculate. (populationeducation.org)
6. Population growth and decline are determined by the number of births, deaths, and
migrations. (ofm.wa.gov) However, its rapid change is influenced by many factors
that fall under the broad categories of demographic characteristics, such as
socioeconomic conditions, transportation infrastructure, natural amenities, and land
use and development over time and space. (Hinduwi.com) Given our population's
current rapid growth, demographic experts predict even more dramatic growth in the
near future, which we now recognize is not ideal due to its certain bad impacts. I
believe our government and several environmental organizations are currently
working to address and prevent these concerns.
7. Yes, because a sustainable planet requires population stabilization. As we all know,
even renewable resources such as water, land, trees, and some energy have a finite
supply. Unfortunately, the cost of all the excessive growth of our population is
now already being paid by endangered plants and animals, as well as by
our increasing volatile and dangerous climate. That is why our government is
constantly enacting laws and programs to address these overpopulation concerns
and to prevent further damage to the environment that can also retaliate to us.

In A Nutshell
3. Age structure influences population dynamics, which are also influenced by economic
development, cultural values, and religion.
4. Overpopulation is harmful in our environment as it can reduce our resources rapidly
as well as cause various environmental concerns.
5. Demographic transition attempts to explain how a country shift from a certain
population size to another.
6. Life expectancy is evidently higher in developed countries than in developing
countries.
7. Human carrying capacity is more complex to determine due to uneven various factors.
