The discovery of oil comes with a huge blessings capable of transforming individual lives communities, states and even countries if well managed. But a situation where the proceeds are miss managed it will turn to be a cause as individual will rise against individual, states Wil rise against starts, countries will rise against countries.
Crude oil has been a blessing to mankind right from it's inception, crude oil and it's byproducts are what almost all our locomotive machines and engines use. The reason why it always comes as an issue for some countries, is as a result of group of persons that will masquerade themselves as leaders and try to siphon the proceeds that will accrue from the sale of crude oil to themselves and leave the majority of the people little to nothing to survive with. So for me, that is the major issue that comes with crude oil and its discovery.
The other one that seems to be another issue for crude oil is the emission of carbon into the air by heavy carbonated machines which to a large extends helps deplete the ozone layer and also increases the case of climate change and unfavorable weather conditions. and I think that is one of the major reasons why electric cars and none combustion engines are heavily in production across Europe and other part of the world, just to help and reduce carbon emission.
So for me crude oil is a blessing but what we are going to do with it, will determine if it will harm us or not.
