How many people can live on planet earth

Technology, rising material consumption, and what could be called a pandemic of “nature deficit disorders” are causing the loss of large areas of wilderness and ecosystem services, but the greatest threat can be traced to growing numbers of people.

The exponential nature of population growth shapes life on earth almost as much as gravity or respiration. But because it is so pervasive, it often goes unseen. One hour from now, earth will show a net increase of more than 9,000 humans, each one needing adequate food, water, shelter, clothing, education, and eventually jobs, not to mention realistic dreams of a better life for themselves and for their children… and on it goes. Our population currently adds 219,000 people every day. That’s a billion every 12-13 years. Will the next billion drive human civilization to a social and ecological tipping point?

“The Eighth Billion” examines the impact of population growth on the health of wildlife and wild places. It also explores the benefits of wildness and natural beauty for producing human enjoyment and inspiration. Wilderness is a form of ecological wealth that, unlike money, is not ours to spend. The quality of our lives and that of future generations depends on efforts to preserve this wealth. Population stabilization and wilderness preservation offer complementary pathways to true prosperity. As imperatives of sustainability, they offer the prospect of a world that is green, prosperous, inspirational, and fair. If we can embrace both pathways, we just might create a world that is worth inheriting!

“It’s not people having large familes…. It’s people doing what people do” (Sir David Attenborough)

2 more people every second, 200,000 more people every day, 80 million more people each year.

According to naturalist Sir David Attenborough, in a Horizon special,
human population density is at the root of every problem he has encountered while filming around the world.
He supports the Population Matters
This Horizon film is an attempt show how water, food and energy will be affected by population growth
as well as an attempt to answer how many people planet earth can actually support.

The UN keeps population records and makes projections for the future.
By mid century there will be 9 billion people – 3 billion more people in the next 40 years.

The history of humanity is one of overcoming environmental limits.
From 1800 onwards there has been a major increase in human population from 1 billion to 7 billion.
Death rates have been controlled by medical and technical advances.
A great achievement.
But living healthily and long has a consequence… Population growth.
Food production cannot increases as much as human population already is.
The physical limits of the earth will determine how many people it can support.

Only 2 1/2 percent of the total amount of water on earth is fresh water and only half of that available for human use.
Over half of that water is used to serve our needs.
More than 1.2 billion people already lack access to safe clean water.
The lion’s share of water is used for food production.
So food production will be affected by water shortages.

Global agriculture is already hitting it’s limit.
We are already using 30-40% of the earth’s tillable surface.
There is no more land to cultivate.
The only way is to raise food productivity.

Some of the largest and riches countries in the world are acquiring land from some of the poorest.
Buying or leasing land in other countries to produce food for their own countries. So the poor countries are producing food for the richest countries rather than themselves and surviving on monetary help from other countries.

Energy production has transformed the earth.
But fossil fuels are getting harder to find.

The more we damage the environment the more we hurt our own self interest.
Most of Africans use less than 1/2 their share, Chinese 2x, Europeans 5x and Americans 4xs their share.
There earth could only support 1 1/2 billion people living in an American lifestyle.

3 ways to solve the problem:
stop consuming resources,
change technology,
reduce population growth.

Continue to damage our ecosystem and we continue to damage ourselves.
The good news – Our intelligence can save us…
The question is, will we use it to do so?

Israeli buys 1,300 monkeys, saving them from harsh fate

After a 20 year struggle, Mazor Farm (located in Israel) which breeds and exports monkeys for medical experiments, will be shut down.

According to an article written by Amir Shouan
Published: 12.23.14, 21:57 / Israel News:

Ady Gil, an animal rights activist who founded Ady Gil World Conservation after selling American Hi Definition (a video projection screen company that provides big-screen projectors to the Academy Awards, the Grammys and more), has purchased the Mazur Farm monkeys.

What comes next?
According to the article:
“And what now, after the purchase of the monkeys?
Initially, Gil says, the animals will have to remain at the farm until a suitable enclosure is erected for them.
“One thing’s for sure,” he says, “they won’t be in cages. I’m against zoos too.”
The options currently being considered by Monkey Rescue include moving the macaques to Havat Bodedim in the south of Israel
or expanding the Ben Shemen Monkey Park.

If you would like to aid the rescued monkeys, you can adopt a monkey or donate whatever amount you like.

Plan B: Mobilizing to Save Civilization

Now on PBS:
“Plan B” provides a glimpse into a new and emerging economy based upon renewable resources as well as strategies to avoid the growing threat of climate change.
As prices rise, oil insecurity deepens,
and concerns about carbon emissions cast a shadow over the future of fossil fuels, wind, solar,
and geothermal energy are replacing fossil fuels at a pace and on a scale previously unimagined.

Hosted by Matt Damon, "Journey to Planet Earth" is a current PBS series that explores the fragile relationship between people and the world they inhabit. The series is designed to help viewers cope with the complexities of developing an agenda to deal with the most important environmental issues of the 21st century. 

Through an interdisciplinary approach, these programs reach beyond the physical sciences and draw connections to politics, economics, sociology, and history.

The series is produced by Emmy Award-winning filmmakers Marilyn & Hal Weiner of Screenscope Films in association with South Carolina ETV.
