Question 17

Can include any statistical factors that influence population growth or decline, but several parameters
are particularly important: population size, density, age structure, fecundity (birth rates), mortality
(death rates), and sex ratio.

Answer 17

Demographics

Question 18

The rise in the number of people on Earth

Answer 18

Population Growth

Question 19

These resources include minerals, plants, water, and wildlife, particularly in the oceans, as well as fossil fuels (oil, gas, and coal). In turn, the removal of resources
frequently results in the release of trash and toxins that degrade the quality of the air and water and endanger the health of both humans and other species

Answer 19

Increasing the number of environmental resources being extracted.

Question 20

Fuel industrial processes, and power transportation (such as cars and planes).

Answer 20

Increased use of fossil fuels to produce electricity

Question 21

For industrial activities, agriculture, recreation, and drinking. Freshwater is extracted from lakes, rivers,
the ground, and man-made reservoirs.

Answer 21

Increase in the use of freshwater

Question 22

To build urban areas, including homes, shops, and highways to accommodate expanding populations,
forests and other habitats are uprooted or destroyed. In addition, when populations rise, more land is
put to use for farming, including raising crops and caring for animals. This in turn has the potential to
reduce species populations, geographic ranges, biodiversity, and change how organisms interact with
one another.

Answer 22

Increasing environmental effects of ecology.

Question 23

Which is reducing the numbers of the exploited species. If additional resources are made available for
the species that remain in the environment, fishing and hunting may also indirectly boost the numbers
of species that are not fished or hunted.

Answer 23

Fishing and hunting are being increased

Question 24

Which increases the spread of invasive species. Invasive species frequently thrive in
disturbed habitats where urbanization has occurred and outcompete native
species. For instance, numerous invasive plant species abound in the areas of
land near to highways and roadways.

Answer 24

Increasing the planned
or unintentional import and export of supplies

Question 25

Diseases can spread quickly among and within communities when people live in heavily populated places. Furthermore, infections can spread fast to new areas due to easier and more frequent transportation.

Answer 25

Spread of illnesses

Question 26
