Surge might be too strong a word, but immigration is a worldwide issue. It can be overwhelming to politicians, like Biden, who try to be accommodating. Large numbers of children seeking asylum at the border.
I keep saying that population growth remains a problem in quite a few countries. It has slowed down in many countries, but remains high in a few; including, from what I understand, some of the small countries of Central America where much of the surge of children at the US border seeking asylum is coming from.
Conditions in those countries is a big problem and the Biden Administration is trying to address that. Reduce the violence and prejudice in those countries.
Better support for organizations such as Planned Parenthood. Biden has lifted the gag order called "Mexico City Policy" against Planned Parenthood Family Planning that Republican presidents impose. The Republican answer seems to be just "build a wall" and send children back to gang infested countries to be killed that way; rather than the possibility of abortian. Very ironic.
This isn't just a US problem. It's a worldwide problem. Europe is somewhat surrounded by countries in Africa and the Middle East that people are desperate to get out of. Climate change is a factor in this problem.
A lot of countries have larger population densities than the US. They might look at our open spaces with envy.
Other countries; like Japan and many European countries, have greater population densities than the US, but they accommodate their population densities better than countries in Central America and the Middle East that are wracked with violence.
In Europe and Japan, population density is better accomidated than in the US. The US devotes too much urban space to parking, freeways and single family residential zones. Immigration is putting pressure on US cities to accomidate more density.
The whole world is more and more interconnected. Getting to the root of the problems of violence, bigotry, drug cartels, oppression and over population is needed. The world needs to evolve. The whole world is being effected by the consequences of these long term issues.
