over the next 30 years,some estimates place the worlds population going from roughly 7.2 billion people in the world to 10 billi
on in 2050. Currently, global food consumption equals around 3000 kilo-calories per person, per day and as global prosperity increases that number is expected to rise to roughly 3500 kilocalories person per day. Counting no other costs other than the cost of production (and this means costs to transport,land use costs, CO2 production,water use,ect), lets say it costs us 1 pollution unit to produce 1000 kilo-calories of food today. What is the current impact in pollution units per day to feed the planet?
(I know there isnt any real problem here to solve, but heres a tip on how to solve greatest to least with decimal problems)
1. Just because a number looks big, doesn't mean it is big
Example: 1.00000000000001 < 1.1
just look at the numbers ^ and dont just hastily read it over assuming that 1.1 is smaller because it "has less digits"
2. Negative numbers are... opposite. and they are less than positive numbers
-3.4 > -4.1
Why is this? Well, if you look on a line, with the point 0 in the middle, you can see that -3.4 is not as far away from 0 as -4.1 is. So the idea is to apply opposite logic for negative numbers
