The demographic bomb is ticking. Large parts of Asia, Africa and Latin America, nevertheless already overcrowded, keep on melting and multiplying at unbelievable rates. I think the animals are much wiser, they melt only in certain seasons, while the human melt every time. Animals even don’t melt any more, if they reach the critical population. In many countries, the critical population is far behind. 100 years ago , e.g., India was half covered by jungle and counted 200 millions inhabitants. Today there is hard to find jungle there any more (consequently is hard to find elephants, tigers and so on). And the population still grows, nevertheless is very poor in majority. I think, there is a close relationship between poverty and high birth rate.
