Envisioning an Alternative Future

摘要: As suggested 40 years ago, the limits to growth as measured by human consumption of net primary production (NPP) may well be reached in next few decades. At that time, we will have planetary further activity. But, long before point is reached, faced with peaks energy and economic directly impact populations. Furthermore, our current industrial civilization powered fossil fuels changing Earth’s climate system accelerating its loss biodiversity wildlife habitats. Due demographic momentum, populations continue for some time despite reduced reproductive rates many developed parts world. There little can done now prevent world population from reaching almost 10 billion 2050.
