What factors influence the impact a population has on its environment?
- consumption of resources such as land, food, water, air, fossil fuels and minerals.
- waste products as a result of consumption such as air and water pollutants, toxic materials and greenhouse gases.
What are the 5 major impacts humans have on the environment?
The five major impacts humans have on the environment include
deforestation, global warming, overharvesting, pollution, and agriculture
. These have contributed to vast species extinctions, incremental and continuous rises in the sea level, and record setting hot temperatures in the earth’s greenhouse atmosphere.
How does population growth affect the environment essay?
Growing population will result in the
depletion of natural resources such as water, fossil fuels (Hubert, 1982); deforestation and loss of ecosystems; and emergence of new diseases
. It will also lead to more starvation, hunger and unhygienic living conditions in poor countries.
What are the 5 factors for population change?
Population growth (or decline) is influenced by many factors that fall into the broad realms of
demographic characteristics, socioeconomic conditions, transportation infrastructure, natural amenities, and land use and development across space and time
.
What are the two major forms of impact on the environment?
The impact of so many humans on the environment takes two major forms:
consumption of resources such as land, food, water, air, fossil fuels and minerals
. waste products as a result of consumption such as air and water pollutants, toxic materials and greenhouse gases.
- Births – usually measured using the birth rate (number of live births per 1,000 of the population per year).
- Deaths – usually measured using the death rate (number of deaths per 1,000 of the population per year).
- Migration – the movement of people in and out of an area.
Environmental Resistance can reduce the reproductive rate and average life span and increase the death rate of young. As Environmental Resistance increases,
population growth slows and eventually stops
, likely near (k).
- Air pollution.
- Soil pollution.
- Noise pollution.
- Water pollution.
- Radioactive pollution.
Environmental factors include
temperature, food, pollutants, population density, sound, light, and parasites
.
As population increases,
per capita available income declines
. People are re- quired to feed more children with the same income. It means more expenditure on consumption and a further fall in already low savings and consequently in the level of investment.
One of the largest environmental effects of human population growth is the problem of global warming
. Some scientists fear that global warming will lead to rising sea levels and extreme weather conditions in the future. In order to support the growing population, forests are being destroyed at an alarming rate.
Emissions do increase as population increases, but not as fast
. As the population of a city increases, the emissions also increase, but the per capita emissions decrease. There are fewer tons of emissions per person as cities grow because cities are more efficient than living dispersed over a large area.
Climate change including Global warming
. Acid rain, photochemical smog and other forms of pollution. Ocean acidification. Displacement/extinction of wildlife.
Rapid population growth continues to be a major underlying force of environmental degradation and a threat to sustainable use of natural resources. It
reduces the quality and quantity of natural resources through overexploitation, intensive farming and land fragmentation
.
Summary:
Overpopulation is the world’s top environmental issue
, followed closely by climate change and the need to develop renewable energy resources to replace fossil fuels, according to a survey of the faculty at the SUNY College of Environmental Science and Forestry.

What is the relationship between biotic potential and environmental resistance? A.
Biotic potential increases the population of a species while environmental resistance decreases its growth
.
Human population growth impacts the Earth system in a variety of ways, including:
Increasing the extraction of resources from the environment
. These resources include fossil fuels (oil, gas, and coal), minerals, trees, water, and wildlife, especially in the oceans.
The three major aspects of the population study are: (i)
Population size and distribution
: How many people are there and where they are located? (ii)Population growth and processes of population change: How the population has grown and changed through time?
