1. Air- We humans and other living creatures depend on air for staying alive, humans, animals and plants all need air to breathe, it’s the main thing that keeps us alive and growing on.
2. Soil- We depend on soil for vegetations and these vegetations keep us alive, it also prevents plants roots from getting out of place and they hold water and nutrients.
3. Water- helps to transport nutrients in our body and regulates the body heat. Without water, the ground will soon become bare and will start to crack, many living organisms will start dying from thirst too.
4. Fire- It protects us from predators, a source of light when we’re lost in the dark, keeps us warm from the cold and vegetation that got burned by fire provides useful nutrients for the soil.
5. Space- Space exploration allows us to discover new materials and objects that may be useful in our life or for the upcoming inventions of the future and it also expands technology .
Without any one of these elements, living species will struggle and deteriorate. They will not be able to increase in population meaning that the species will disappear in the next generation thus becoming extinct. All living things will die from hunger, diseases, cold and lack of natural resources .

Answer:
17,190 years
Explanation:
Each isotope has a characteristic half-life, which is the time required for half of that isotope to decay. After one half-life has elapsed, 50% of the isotope has decayed and 50% remains. After two half-lives, 75% has decayed and 25% remains. After three half-lives, 87.5% has decayed and 12.5% remains. For carbon-14, which has a half-life of 5,730 years, three half-lives corresponds to 17,190 years.
