Whatever the case, Lithium does cause environmental pollution and is a bio hazard. Presently, Lithium extraction is poorly regulated where it is done (mostly Africa and Latin America) and is the cause of many generations of humans becoming inflicted with diseases and disorders. The alternative to fossil fuels should be bio fuels and not something which will harm the people more. Anything we mine out of the earth to burn will definitely cause harmful pollution.

This is more complex than it appears. Use of electricity in refineries is not limited to produce one specific commodity. As is generally known, crude oil is used to extract many other types of fuels and lubricants. Hence, it will be incorrect to say 1 lts of Petrol extraction requires 1.3 kWh of electricity since using that electricity, more products might have been manufactured.
For a very bare and crude counter, 1lts of Petrol in a nexon can drive for 17-18 kms while 1.3 kwh of electricity can drive a nexon ev for only 13-14 kms. Since this depends on driving conditions and many other factors, I won't consider this a fair reply.
In this scenario, I generally consider EV's equally polluting to normal ICE cars.

Absolutely not. However, the current legislation itself is full of loopholes and useless. If you drive on a highway, you will observe many trucks and lorries emitting thick and black smoke good enough to smear a white paper to pitch black in just 20 seconds. It is not about cancelling the present transportation, it is about regulating it strictly. Also, alternative fuels like biogas and biodiesel can be used and current engines be modified accordingly by making supply of conversion kits mandatory. This will serve the green purpose as well as increase the life of these trucks and lorries, thereby reducing junk waste.

What this analogy misses is that the fuel manufactured by using this electricity is used in the cars as well as the trucks transporting it to my car. Furthermore, most refineries generally themselves generate electricity using the by-products (petcoke which has higher calorific value than the regular coal) which is way greener compared to electricity generated by ordinary thermal power plants so this component is off. Regarding shipping from middle east, I 100% agree to it.

If the Indian Government would have understood, it would not have been involved in executing inordinate construction projects digging every single mountain with terrain or reclaiming lands from the sea by destroying mangroves.
Also, the current policy of blending ethanol in petrol without taking any opinion from the public is only leading to damaged cars and increase of junk cars beyond the limit of processing capacity available in India is nothing but a very high handed decision.
Just for reference, my 8 month old Brezza which is E10 compliant has to be compulsorily fed E15 or possibly higher Ethanol blended fuel giving me less fuel efficiency, performance and degrading the service life of my car. I genuinely sometimes feel that this is a clear propoganda on behalf of the vested parties to show ICE cars in bad light and have them banned.
IMO, the present fuels need to be replaced by biofuels till the time we develop the technology and protocols to safely harvest and recycle Lithium and in the longer run, depend on H2O batteries which prima facie seem to be the safest and greenest alternative.
Regarding Mr. Guterres, he is a hardened politician (former two PM of Portugal) so I can't take his word with a pinch (A ladle spoonful) of salt.
Everything that is made has to be destroyed (albeit Organically). No one escapes the ultimate destiny.
Also, isn't the problem rising temperatures?
