I wouldn't because of overpopulation.
Currently, there are over 7.6 billion people in the world.
It takes a approximate dozen years for an increase in population by a billion. For example, it took 12 years for the population in the world to grow from 6 billion to 7 billion, between 1999 and 2011.
The 7.6 billion currently on earth represents just about 7% of the entire number of humans since humans came into existence.
In 1985, the demand for resources exceeded its supply. The distribution of the available resources was quite equitable before 1985, where there was equilibrium between the demand and the supply of resources. Nevertheless, the emergence of overpopulation led to disequilibrium where the resources could not cater for the whole population.
It only took 40 years for the population to double from 3 billion in 1960 to 6 billion in 2000. This is super rapid growth compared to the beginning of the 19th century which had a population of 1 billion and took a whole century to be at 2 billion.
Every time two people do more than just replace themselves (or arguably have any kids at all to be fair) they contribute to this problem, which is destroying the planet we live on and bring our kids into. The more people who think that their contribution doesn't matter, or that somehow it doesn't apply to them, the bigger the problem gets, it is incredibly selfish IMO...
