Biodiversity refers to the variety of organisms found in a particular
habitat.
It is important to maintain biodiversity because we rely on it
for ecosystem services, which fall into four main categories:
provisioning, regulating, cultural, and supporting.
The earth provides
these to us for free and they are critical to achieving a planet in
balance.
As diet needs differ from individual to individual, different people need different foods for different lifestyles.
That main variables that these two food pyramids focus on are non-sedentary and sedentary lifestyles. Ask yourself this question. Do you spend most of your waking hours exerting your body and handling heavy objects? If so, then you’ll need a non-sedentary diet. High amounts of carbohydrates from grains are required to provide the energy one needs for long strenuous activities like manual labor. If you work in an office most of the day like me, you’ll need a sedentary diet.
