Human overpopulation is not only very dangerous for the natural world which we have done so much to destroy but also to ourselves. The more humans there are on the planet there will be more suffering, strife and wars.
Hopefully nature will readdress the balance with natural catastrphes which will signifcantly lower the population.
If we decide to take responsibilty for ourselves a solution would be to sterilise large sections of the population.
Humanity has got to remember that it is just one of billions of different species on this planet and it hasno right or entitlement to flourish at the expense of other species or the detriment of the natural world. I hope we get a rude reminder that we're nothing special on this planet!
