Can the earth supply all the materials needed for billions of people to enjoy a reasonable life? keep in mind that as we move forward in years the population increases. provide good examples to support your answer.

Explanation:

Yes, earth provides all materials to the people to lead a reasonable life. The earth provides renewable as well as non-renewable resources, which can be useful for generation of thermal and electrical energy, source of food and raw materials required for the purpose of construction. But with the increase in the population worldwide, the resource utilization will increase and possibly the resources will be limited in future.

For example, the use of fossil fuels for the purpose of thermal and electrical energy generation and increase in the dependency worldwide is likely to limit the available concentration of fossil fuels on earth and these resources will not be available in future.  

81 is a composite number.
