Environmental Mathematics LESSON 5

Population Growth

An increase in the number of individuals in a population over time.

·        often due to high birth rates, reduced mortality, or increased immigration.

Causes of Population Growth

·        Improved healthcare leading to lower mortality rates.

·        High fertility rates due to cultural, religious, or economic factors.

• Immigration and favorable migration policies.

• Economic opportunities attracting people to specific regions.

Population Decline

A decrease in the number of individuals
·        often resulting from low birth rates, high mortality, emigration, or a combination of these factors.

Causes of Population Decline

·        Declining fertility rates.

• High emigration due to conflict, lack of jobs, or political instability.

• Public health crises, pandemics, or natural disasters increasing mortality.

Exponential Growth Model

It describes a situation where the rate of change of a quantity is proportional to its current value. 

·        It is commonly used in population studies, finance, biology, and other fields.

2.718

Euler’s number?

ENVIRONMENTAL STATISTICS AND DATA ANALYSIS

·        It involves the collection, analysis, and interpretation of data related to the environment.

Pollution Analysis

Monitoring air, water, and soil pollution levels and their impacts on ecosystems.

Climate Data Analysis

Analyzing temperature, precipitation, and CO2 levels to track climate change.

Biodiversity Metrics

Measuring species richness, abundance, and extinction rates.

Descriptive Statistics

For summarizing data trends (mean, median, variance, etc.)

Inferential Statistics

For hypothesis testing and making predictions.

Time Series Analysis

For studying patterns over time (e.g temperature trends)

Machine Learning

For advanced predictions and pattern recognition in large data sets.
