Giant King Grass has already been successfully grown in China. Giant King Grass has similar characteristics to sugar cane but is not a food crop as it develops cellulosic material rather than sugar. It has been demonstrated to have the highest energy yield per hectare of potential energy crops. The government of Thailand has set a target of 3,700 MW of biomass capacity by 2022.
It is usually represented as follows: Rate of Natural Increase = Crude Birth Rate-Crude Death Rate This version of the rate of natural increase shows net addition of people from births and deaths per thousand people in the population.
You can add two natural numbers together, and you will always get another natural number, as in the famous fact that one and one are two. Subtraction, on the other hand, is trickier. If you subtract a number, for example the number 5, from itself, you get something new, something that is not a natural number at all. We call it the number 0 or zero. And if you subtract a number, again say 5, from a smaller number, say 3, then you get something else that is new, namely a negative integer, which in this case is -2, called minus two.
