Answer:
a. There is no cause for concern because human population growth is not correlated with the global ecological footprint
Explanation:
The global ecological footprint needs to use as precise methodology as possible. The reason why it has to have very prices methodology is so that the data is the best possible, and once the data is presenting the reality, than the problem can be addressed adequately and a proper and an efficient solution can be constructed. By ignoring the growth of the human population, the methodology practically suggests that the human are not related to the global ecological footprint, which is not true. The human population is actually the one that has the biggest ecological footprint, so the changes in the population always have to be taken in consideration, as without it there can not be a proper response because of the false data.
