Although it is widely held that infections and eating difficulties are hallmarks of advanced dementia,25 there are few prospective data on the incidence of these complications. Over the course of 18 months, more than half of the residents in our study had infectious episodes, and 86% had eating problems.
So 10 billion people is the uppermost population limit where food is concerned. Because it's extremely unlikely that everyone will agree to stop eating meat, Wilson thinks the maximum carrying capacity of the Earth based on food resources will most likely fall short of 10 billion.
The weight of an object is a force and is so is measured in Newtons, while the mass of an object is measured in kilograms. To find the weight of an object you simply multiply its mass (in kilograms) by the force of the Earth's gravity on 1 kg (10N).On the Earth the weight of our crate will be 50x10 = 500 N.Now imagine taking the crate to the Moon and lifting it up there.Its mass is still 50 kg but the Moon's gravitational pull is only about 1/6 of the Earth's in other words about 1.6 N/kg. This means that the weight of our crate on the Moon will be 50x1.6 = 80 N and so it will be much easier to lift up.ow imagine taking the crate to the Moon and lifting it up there.
