Hey, I am going to tell what could happen when the oil industries decrease
A futurist and a clean energy expert Toni Seba says that he thinks that electric cars will destroy the oil industry and the peak of the oil industry will be 100 billion barrels in 2020 then will lose 70 million barrels in 2030.
The average cost in 2019 from what WTI (West Texas Intermediate) is $58.82 US Dollars = $461.76 HK Dollars per oil barrel.
For example a cruise ship or a fancy house what do you think it got there and what materials such as gold, silver, and copper or metal, plastic and other common materials. In poor places around such as Bangladesh and many more other poor countries with serious problems with last amount of important minerals to survive in different situations in life.
The pollution around the world in the ocean is high and most of the products in the ocean is plastic or materials which take a miracle to dissolve and plastic is made out of oil and also pollution is from cars and factories which produces CO2 which is made from fuel which is made out of oil.
Here we have a small normal car and normal public bus but when oil runs you would not see this often you will see more electrical vehicles which a starting to produces in many companies such as Mercedes-Benz, BMW, and Rolls Royce and many more other car companies will start to stop using fossil fuels such as diesel or gasoline and using batteries which will regenerate over an amount of time until use
By 2030, I think that the oil around the world would have decreased to 85% because already today oil is not used and electric batteries.
By 2030, The sustainable development goals say that all fossil fuels which affect the ocean and air which affects the animals which need these with them to survive in the world.
