Unless extraterrestrial humans enter Earth or people leave to inhabit another planet, net global immigration and emigration are both zero. Thus, to reduce the rate of global population change, the number of births must be reduced or the number of deaths must be increased.
Answer:
Explanation:
Alright so the way to do this is to use properties of integrals to make our life easier.
So we have:

So lets break this up into two different integrals that represent the same area.

Lets think about what is going on up there. The integral from four to zero gives us the area under the curve of f(x) from four to zero. If we subtract this from the integral from one to zero (the area under f from one to zero) we are left with the area under f from four to one! Hence:

But since we have these values we can say that:
-3 - 2 = -5
Which means that
= -5
So now we can evaluate 
Lets first break up our integrand into two integrals
= 
Now we can evaluate this:
We know that
= -5
So:
where x is evaluated at 4 to 1 so
-15 + 2(3)
So we are left with -15 + 6 = -9
Answer:
The use of improved plant hybrids and agricultural chemicals
Explanation:
According to history, India witnesses a huge surge in the the amount of wheat produced in the country between 1950 - 1990 ; This surge in production has made wheat the main cereal crop in the country with about 30 million of hectares of land being used to cultivate the cereal crop as of today. The huge surge over the 40 year period whereby production more than doubled could be attributed to the advancement and upgrade in the crop type and agricultural chemicals being adopted. These hybrid crops germinated faster and produced good yield which boasted more production and drove revenue to better height.
