If hybrid battery and hybrid system so easy to spoil and so hard and expensive to repair, then how is the "hybrid is greener and better for environment"?

Not even used for few years then throw away. Is this even justify the fossil fuel savings that hybrid system uses vs normal ICE system.

like this a toyota camry 2,5NA is even more environmental friendly compared to hybrids, because NA cars is more durable, can be driven for many years.
