Humans are the only species on earth, who change the environment in many ways, from overpopulation, pollution, burning fossil fuels, deforestation, urban growth, cluttering space with debris, etc.
Interesting if we look at population growth, in the US it is entirely due to illegal migration and a failed border policy. If it is allowed to continue, the face of the country will eventually look very different, for better or for worse. I suspect the latter.
If we look anywhere else, it appears to always show highest population growth rate in countries which are poorly governed. Where there is poverty, violence and where there is a lack of the ability for self care. It follows that all the countries with a very high population growth rate, have to rely on financial assistance coming from countries with a negative population growth rate.
