What are some of the concerns associated with our increasing population and consumption of resources?
Ugo [173]

Explanation:

As human population increases the rate of consumption of resources also increases. Economists postulates that available resources with which to satisfy our unlimited wants as a population is highly limited.

  • Increase in population leads to an increasing pressure on available resources such as freshwater, land, air, energy e.t.c.
  • Increasing population easily leads to deforestation. Deforestation is the loss of forest. Forest trees are used in construction of houses and industries. Forests also takes up space and they might have to be plundered to make way for new buildings. Eventually, the forest will be lost.
  • Decrease in standard of living: increasing population will lead to a low standard of living. Resources meant to accommodate a certain number of people will no longer be sufficient for them.
  • High poverty rate; if population continues to rise, the rate of poverty will increase too. There will be limited resources to cater for the well being of the populace as a whole.

KIM [24]

Explanation:

1. A decrease in the number of greenhouse gases that humans produce will result in lowered global temperatures. This will allow the ice sheets in the polar regions to increase increasing also albedo.

2. Using light-colored building materials on houses and pavement in urban centers will work towards increasing albedo as more sunlight is refelcted back by built environments.

3. Decreased deforestation/increase in aforestation increases the earth’s sirface albedo because vegetation reflects back more sunlight than the earth’s bare surface.
