>>9297Yeah, they were pushing "by 2000" and "by 2020" in the 1980's university courses. A lot easier now, than when Q-link was one of the choice internet providers, to search up a professor's history to find out if they are professionals or protestors. Don't worry about any bullcrap an "educator" gives you that is not practically usable and provable; chemistry, physics, and math, YES, politics, history, and doomsday-end-is-near, NO.
Energy resources are renewable. Petroleum is renews by a high-pressure mineral chemical reaction, oil fields can be drained but over tens-of-thousands of years they will refill.
Dedicated campaigns to wipe out the rainforests and poison the algae in the ocean would cause an extinction event. Pump Industrial Revolution level smog into the air by all 8 billion people could cause actual problems. Extremely hard to do though.
If you really want to improve the world environment just reduce human population. That will fix the ecology extremely fast.
