The future is looking very bleak for both us & the rest of the bio diversity. The current world human population is around 7 billion & set to rise to 9 billion by 2050. Food production will have to increase by 70% to feed them ( even now 1 billion people don't have enough to eat) which means that every parcel of cultivatable land will have to be turned over to producing crops, thousands of eco systems around the world will be destroyed for ever.
If you add to that Global warming,( i.e. places that have a lot of rain will have more & those that have little rain will have less,)meaning crop production will be compromised & the melting of the ice caps, raising sea levels, vast quantities of land will be lost, forcing millions of people to migrate to other areas & countries already in difficulty. It's not unconcievable that there will be both international & civil wars as nations, even communities try to keep their ever decreasing ressourses for themselves.
Water will be a major problem, & there won't be any to spare for the few wild animals that have managed to survive.
Fact or fantasy..........discuss.
