You are wonderful! This was terrifying at first, when I realized how big it is! Then I calmed down after a few seconds.... Thank you! There might not be an impact, many people say the ships 'float' above the ground, or some have legs, I have not seen, as far as I can remember, one that is close to the ground, but that is what the reports frequently say.
How many European parents put their kids on boats during the potato famine, or during WW2, or thousands of other times all around the world? The problem is that the situation is so bad in these countries they are coming from, that the feel like the only way they might survive is to try almost anything. This is like someone pushing spray foam through a hole in a wall and no one is looking at where that foam is coming from, only that it is coming out the other side and thinking if we put a block up over where it is coming out of, then it won't still flow somewhere. Do some research and don't be so concerned about if people are going to be causing yourself to somehow be in worse situation, look further, and find out what your leaders are doing, and let's get this situation fixed from where the problem is, so these people can live in their own countries in peace and happiness.
