Petroleum is a fossil fuel. Fossil fuels have many disadvantages:

1. They add carbon to the atmosphere, causing global warming.
2. They are very limited in quantity and become more expensive to find and refine.
3. They are biologically hazardous and can pollute ground and water

One is that we use fossil fuels for like running our cars and providing electricity. So we use them for important things, but one day we will run out of fossil fuels and we will have to find replacements. In some places they do use things like windmills and water generator for electricity, but most places rely on them.

Another is that using fossil fuels is bad for the environment, and the pollution is causing global warming and climate change.
