Question

An increasing population is a threat to Biosphere.Justify the statement

Answer 1

As populations become more affluent, there is a greater demand for natural renewable and non-renewable resources. Timber is in demand for housing, and so forest ecosystems decline. Demand for cars rises and so the demand for steel, metals, rubber and petroleum increase along with the impacts they have on the biosphere. This in turn, creates more demand for roads and other infrastructure, which means more cement quarries must be opened - further impacting ecosystems. Its also been shown that as people become more wealthy, they like to eat more beef and other meats. This in turn, means more land must be converted 

Answer 2

Answer:

More individuals implies increased demand for resources and agricultural land to feed more individuals and thus affect the biosphere.

Explanation:

• As population’s increases, agricultural development tends to be the first effect on the biosphere to feed a increasing population.
• This transforms the natural biomes into human biomes such as cattle range land, food crop farming. Food manufacturing has now affected almost all of the initial biomes.

• There is a higher demand for natural renewable and non-renewable resources as populations become more affluent.
• Timber is in housing demand, and ecosystems in the forest are declining.
• Demand for vehicles is rising, increasing demand for steel, metals, rubber and oil along with their impact on the biosphere.
• This in turn generates more demand for highways and other infrastructure, which implies opening up more cement quarries-further impacting ecosystems.
• It has also been shown that they like to consume more beef and other meats as individuals become wealthier.
• This in turn implies that more land for cows, sheep, and so on must be transformed into grazing land.
