We recommend You, dear visitor, to take a good look at this website! http://worldpopulationhistory.org
These facts are scary, but imagine, if we continue to grow with 6-700% over the next 100 years, we will have 56 BILLION people on the planet!!! Is there anybody in this world, who thinks the planet can handle (not 56 billion) but just 20 billion, knowing how bad it is already TODAY? Why don't we "all of us" on this planet, face reality? While there is still time to act upon it.
Education is needed on a global basis, to teach everybody the importance of a quality reduction in population to save our beautiful planet. Believe it or not, but SWEDEN has also grown in population with over 600% in the past 100 years. With 2-3billion people on the planet, we would not cause any Global warming, which we are now doing.
How about if we start promoting & thinking QUALITY instead of QUANTITY. By motivating countries to focus on neccessary education and thus enable promotion of wholesome families on a Global basis, with focus on having 1 or max 2 children. This will enable themselves a quality life for their whole family with greater opportunity for a better education also for their own children.
By applying this approach, we will create a slow but steady and healthy decrease of population until we reach our goal - instead of facing future turmoil, anarchy and civil unrest all over the planet. (Something, which is now starting to become appearant, as a result of lack of resources, which now can be vitnessed in many places.) The planet in recent years as a result, has also started to turn hostile again, with threats of war in many places.
P.S. There are NO other planets in our own "Planet Earth" vicinity, which are inhabitable, unless Elon Musk et.al. hurries up, invents and builds very large spaceships, able to move much faster than the speed of light, so they can take us there!
