What if straight was a minority ?

If Straight was a minority then there would be less population as compared to today and population explosion wouldn’t even exist. If this was the case, then less people would be affected during any pandemic and the death rate would be low. But if we think about it today, it would seem pretty weird but we don’t know about the future. I think if there is less population , it would mean less pollution and more healthy humans. As a result the average age of humans may increase. But there is also a huge drawback that many people’s genes would end with their death. Less population may also result in increased standard of living in urban as well as rural areas. But overall it would affect the balance of human population, male-female ratio ,etc.

I personally think that i would keep the world as it is without changing it ^-^ .
