Natural resources:
Things from nature such as water, fruits, animals, caves, trees, and many different types of energy (such as heat and light) which are there for us to use so that we can live. We have to learn not to take too much from the natural resources so that there is enough to last forever. Depletion of our natural resources such as Fossil Fuels, Oil, Coal and Natural Gas which we use everyday means we have to find new sources of fuel to replace them before they run out.Can you think of other natural resources which we are depleting.
