These are all the solutions to the problems that we will face when oil runs out.
Without any oil, there will be no transportation. This means people will start to walk which will not pollute the world.
The oil energy is connected to the oil that we use, so if it runs out the energy will follow. because of this issue, humans will have to use natural energy which will heal mother nature.
When the oil runs out there will be no plastic as it is produced from oil. However, this is very good for the environment because we will start torecycle our rubbish. by doing this we are respecting our place and healing mother nature.
