Question

How can natural resources be used to fulfill our need?

Answer 1

Water is required by all living things to maintain the flow of nutrients within the body and excrete wastes. The hydrologic cycle is the ring that rules all other cycles.

Clean Air provides Oxygen for converting carbohydrates to energy to power growth and mobility ( in the case animals).

All living organisms are made of Carbon and therefore are part of the Earth’s carbon cycle — including plants and animals and fossil carbon in the form of fossil fuels.

Iron moves oxygen around in the bloodstream and provides the structural backbone for the ongoing Iron Age — with steel being an alloy of iron.

Silicon (sand) is the inert filler of all earth materials that comprise the earth.

Answer 2

Earth's natural resources.

●The cars that you and your parents drive rely on petrol, made from oil.

◆Of course the biggest, and most important resource, is food. This is also the route of some of the major problems in the world.


●Other natural resources that need some for of control and management to remain sustainable are things such as soil, water, fish and wildlife.

◆Fossil Fuels are the first group of non-renewable resources. These include oil, coal and natural gas, which will all run out in the future. Unfortunately humans have greatly increased their use of these fuels over the past 200 years, which has led to them potentially running out quite soon.

●We have not discovered all the coal, oil and natural gas deposits in the world, but they are becoming increasingly hard to find and then to exploit. The oil companies looking for new deposits spend millions of pounds every year.
One estimate suggests that:
Most oil reserves in the world will run out within the next 50 years. .

◆Coal reserves are expected to last over 300 years. This estimate has consistently increased over the past few years as more fuel-efficient methods .

●Natural gas is becoming increasingly used as an alternative fuel to coal or oil, and the latest estimates suggest that there is enough .

◆ The two most widely used are nuclear energy and hydro-electric power. Although nuclear energy does rely on a finite natural resource (uranium, plutonium or other similar minerals), it uses so little that there is very little chance of the reserves running out.
