It can lead to food Scarcity, since the erosion will wash away the food which farmers have planted.
New Zealand and the outback
Answer:
The speed of the current climate change is faster than most of the past events, making it more difficult for human societies and the natural world to adapt. Now, day by day new technologies are invented, causing more pollution than in the past. It is important now because we are developing in very fast steps and something should be done.
From almost the creation of the first true maps of the Earth, people started seeing how continents would be able to fit together. In particular, people noticed that South America fits almost exactly into Africa.
You should be aware that while world maps were around early in the 1600’s and better defined by the end of the 1700’s, those maps were not ‘public’ but were treated as state secrets. And so it was not till much later that the broader ‘science’ community had access to good quality and accurate world maps.
It is now known that most of the major continental masses can be fit together in a jigsaw process. In fact we now know that the continents were indeed once all joined together as one land mass – the super-continent of Pangaea.
If you look at most world maps you will ponder how this is evidence, as the continents really don’t appear to ‘fit’ together very well. What you need to understand is that the vast majority of maps are drawn using a map projection that has the north and south poles (which are points) are a line the width of the map at the top and bottom. This means that the map distorts the true shape of the Earth’s land and oceans as you love closer to the poles. Some other map projections distort less, but have the map shape looking like segments of an orange. See here for a range of map projections. Check out the way Greenland changes size in each!
