What do Iranian people do with the goldfish after Persian New Year is over?
People who care about them try releasing them in ponds within nearby parks or in rivers. I suspect many of them don't survive in those environments due to multiple shocks they tolerate because of changes of temperature, PH, saltiness, etc. But I also think environmentally conscious people have already stopped buying these.In my experience, the poor gold fish don't make it very long after the celebrations if they aren't released. Sometimes 2-3 months but rarely more ( especially for those in a fish bowl as opposed to aquarium with air pumps). They usually die within a couple of weeks. Many goldfish already carry infections by the time they are sold. Look at a fairly common condition they are kept at before they are sold:One fish with infection in there can basically pass it on to everybody within hours. This is not even a tradition rooted in Iranian culture. It is more of a chinese tradition, that somehow has made it to people's homes in the past century. There is an active campaign in Iran to stop the trade of these fish near new years.
How do Middle Eastern countries enforce border control?
It depends upon the country. Saudi Arabia, which has strict terrorism laws has strict borders with Iranian allies. Like, look at Yemen and Saudi ARAbia,This is the cause of Iranian terrorist allies called Al-Houthis in Yemen and southern Saudi ARabia.Now, look at the Saudi ARAbian-Iraqi border. ISIS has entered Syria and Iraq and refugees are trying to flee from Fallujah, Iraq and ISIS has took control of Iraq. Another thing is the migrant flow to Arabian countries and Arabian countries are strict on the visas and illegal migrants are completely banned. Munich has designed a new Hi-Tech border fence between Iraq and Saudi Arabia.(The road to Iraq on the left)Kuwait and Iraq are very bad friends since the Gulf war Kuwait invasion by Saddam Hussain of Iraq in 1991.Kuwait is also one of the richest countries in the world, so there is a chance of migrant flow from Iraq.Saudi Arabia has some minor disputes with UAE and Kuwait. Saudi Arabia has the Kuwait-Saudi Arabia Neutral zone which is of [math]5,770 \text{km}^2[/math]. The neutral zone was equally divided between Kuwait and Saudi Arabia.The UAE-Saudi Border is a bit smoother. Abu Dhabi is the only emirate which borders the country. UAE will always obey Saudi Arabia and is always its ally.Qatar and Saudi Arabia are good friends and have no particular disputes.Bahrain and Qatar are disputed over an archipelago called Hawar Islands. These islands are nearer to the Rayyan Province on the western coast of Qatar but administered and internationally recognized under the Southern Governorate of Bahrain. Qatar and Bahrain only share a small maritime border.The Bahrain-Saudi Border is not a maritime border and the King Fahd Causeway is one of the most important routes in Arabia as it connects the small Island of Bahrain to the whole of the Arabian Peninsula at Al Khobar, Eastern Province. The Passport Island is the largest and it is the border island of Saudi ARabia and Bahrain. The Saudi Tower is on the left side and the other on the right side.(Source: Google Earth)
Has canada treated its first nations badly?
Yes, and they continue to, but Canadians are too overzealously patriotic to admit to it. Those who actually take the time to learn about such treatment will probably act as apologists with their "but the US did ____" excuses. New Zealand is the model for treatment of its indigenous population (at present, not in the past). This is the consensus among liberal academics virtually everywhere.
