HUMAN ACTIVITIES THAT TREATEN BIODIVERSITY
World population growth through history
2014 - 7 bllion people
about 9 billion people by the year 2050
Thomas Malthus
in 1798 he came up with the concept of carrying capacity basically
What actually is the carrying capacity of planet Earth for humans?
That's human technology the ability to come up with answers to problems that are facng us at almost every term.
in fact there are some estimates that suggest if we all did with less and lived at the lowest possible level for existence
Earth could support an estimated forty billion people
The world's wealthiest
16% of people on Earth
Use 80% of the World's resourses
we recoognize that human population is growing
we recognize that resource utilization is much higher in some countries than in others
Primary objective
biodiversity
Human population growth and resource utilization of huge affects not just in our social and economic well being but of course on biodiversity
Pioneering papers on this was published in 2003 by McKee and collegues
they measured a number of factors in a 114 counrties and what they discoverd was that out off all the factors that they looked at
human population growth and species richness werw tighty linked, in other worlds if you were to slow population growth that might be sufficent to stop drops in species richness
They suggested that all you need to know is population size plug this into the equation and you can figure out in a given place
What effect it's going to have biodiversity?
threatend species increase by 7% in 2020
threatend species increase by 14% in 2050
