I'm speaking in a general sense based on recent activity in the Mediterranean and the English Channel, that particular photo, relevant or not is not untypical of what goes on regularly. The fate of those particular individuals is of no concern to me whatsoever, they represent a bigger problem.
I don't know where you are situated, but Europe, particularly the UK/Eire isn't capable, in terms of landmass, population and infrastructure to absorb and handle an unmitigated number of immigrants. Therein lies the issue.
The plight of a continent(Africa) is not resolved by all and sundry getting up and moving en masse. You are simply firefighting (and poorly at that) and not addressing the true issues.
Africa is due to have another population explosion and if you think they're suffering now, give it another 50 years.
If Africans want to prosper in the long-term, they need to become truly self-sufficient.
I live in the U.S. and I have family in Europe. I guess you could say I am international by association.
You are completely right in that the world does not have the resources to provide for the current population. Humans are headed for major disasters and perhaps extinction. All that we are experiencing presently can be linked to over-population. Why nitpick over who is immigrating wherever they can in search of a better life. In a global sense, we are likely to end up annihilating ourselves sooner rather than later.
To say that a large portion of the world's population needs to become self-sufficient is wishful thinking because it is not going to happen. Probably not in my lifetime, but not too long into the future we may find ourselves reduced to all manner of atrocities in our efforts to continue to exist. We like to believe the fittest will survive, but I am not sure even they will manage this.
All one needs to do is to look at nature. Rodents have a history of overpopulating. Do you know how the rodent population controls itself? When their environment becomes too overcrowded, they cannibalize one another. This is not a pleasant way to keep population under control. In the 60's I read an article which suggested we humans would become like rodents, eating one another for survival. Seems a bit far-fetched until you realize that human cannibalism has a long history and not just among primitive peoples. Have you ever read or heard about the Donner Party? They were a group of pioneers who resorted to cannibalism when trapped in the Sierra Nevada. About half of them survived by eating those who had died.
These are things no one wants to think about. Instead we engage in distractions like folks migrating from one impoverished wasteland to somewhere where they imagine life will be better, but often isn't. Or which currency we will use to become hopefully more stable financially. It's a grim picture which hopefully I will not experience in my few remaining years.
