Many oil blocks even in bay of bengal and arabian sea havn't seen commercial drilling due to unvabourable profit to cost ratio and we are talking about moon mining....trump loves to be in news headlines so,he declared this bizzare future plan but we shouldn't waste our time by thinking about it...
We forever can't exploit earth resources.
Mining and Drilling for oil and resources is responsible for many earthquakes and deterioration of ecosystems.
The resources on earth are limited while there is limitless resources in space.
Currently moon mining will only be done for high value strategic resources but in the future some 100 to 200 years later u may see Steel and Titanium coming from outer space.
Still all of this is just fantasy for now so there isn't much of a point taking about this.
