The correct answer is B. Calculate your ecological footprint
Step-by-step explanation:
Individual impact on the environment is commonly measured using the "ecological footprint" which is a concept in ecology that refers to the number of sources and elements you "take" from nature to support a certain lifestyle and therefore the impact you have on the environment. This differs according to the country as there are differences in each and also depends on the lifestyle of every person as certain individuals consume more than others, for example, a person that only uses a vehicle is more likely to have a higher ecological footprint that one that only uses a bike. Thus, if you want to determine your specific impacts on the environment the best is to calculate your ecological footprint.
