From my prior knowledge it’s smuggling things like drugs and guns from the border so it made it hard for those to move to the u.s
Sorry if this doesn’t help
Hey there! I'm happy to help!
For a place to be densely populated, you have to have a small land area and lots of people. Usually very small areas are very densely populated. The smallest territory in Australia is Australian Capital Territory (Canberra). It is just the Australian capital, so it is a small territory and there are definitely lots of people living near the capital, so we have ticked small area and lots of people off our list to have it be densely populate, so this territory is the most densely populated Australian territory.
Have a wonderful day! :D
Answer:
Climate change threatens coastal areas, which are already stressed by human activity, pollution, invasive species, and storms. Sea level rise could erode and inundate coastal ecosystems and eliminate wetlands. Warmer and more acidic oceans are likely to disrupt coastal and marine ecosystems.
