This is spot on. People look at % values instead of the bigger picture, as in what would happen if that 5% wasn't there.
Look at it from another example. If you were a healthy person and ate a burger and needed 30mins execrise to burn the energy off. Now add 5% more fat to the burger and you still only did 30mins exercise over a LONG time that person will gain weight. Now at the time 5% extra fat doesn't seem like much but it will have bad results on the persons health if he doesn't adjust for it.
Same thing goes for weather. Every few years we get wierd weather so it balances out what nature has contributed to it. However if it cannot blance out the extra 5% humans add to it, eventually that will build up and cause catastrophic things to happen. |
Also, when the person gets fatter, and runs the same distance, they will start to burn more calories, because they have to move more weight around. So in the end, it will reach an equillibrium.
