Draw a line graph of the population data from 2014-2020 and explain the trend, and calculate the population in 2017 and the percent growth since 2014.

To draw a line graph for the given data:

• X-axis (Horizontal): Label this "Year". Mark the years from 2014 to 2020 at equal intervals.
• Y-axis (Vertical): Label this "Population size (in millions)". Choose a suitable scale, starting from a value slightly below 54.55 (e.g., 54 million) and extending to a value slightly above 59.62 (e.g., 60 million).
• Plotting points: Plot each data point:
  • (2014, 54.55)
  • (2015, 55.39)
  • (2016, 56.2)
  • (2017, 57)
  • (2018, 57.78)
  • (2019, 58.78)
  • (2020, 59.62)
• Connecting points: Draw straight lines to connect the plotted points in chronological order.
• Title: Give the graph a clear title, such as "Population Growth from 2014 to 2020".

(Assuming "QUESTION 3.1" refers to the graph drawn for 5.1)
The graph shows a positive relationship or an increasing trend. As the years progress from 2014 to 2020, the population size consistently increases.

From the table, the population size in 2017 is:

• Increased demand for food, leading to pressure to increase agricultural output.
• Need for intensification of farming practices, such as using more fertilizers, pesticides, and high-yield crop varieties.
• Expansion of agricultural land, often leading to deforestation and loss of natural habitats.
• Increased pressure on natural resources like water and fertile soil.
• Potential for food insecurity if agricultural production cannot keep pace with demand.

• Food demand for direct human consumption.
• Feed demand for livestock, as meat and dairy consumption often rise with population.
• Industrial demand for raw materials (e.g., cotton, rubber, biofuels).
