Perhaps it's time

"Three and a half million years separate the individual who left these footprints in the sands of Africa from the one who left them on the moon.  A mere blink in the eye of evolution.  Using his burgeoning intelligence, this most successful of all mammals has exploited the environment to produce food for an ever-increasing population.  In spite of disasters when civilisations have over-reached themselves, that process has continued, indeed accelerated, even today.  Now mankind is looking for food, not just on this planet but on others.  Perhaps the time has now come to put that process into reverse.  Instead of controlling the environment for the benefit of the population, perhaps it's time we control the population to allow the survival of the environment."  2002 Sir David Attenborough 

Population control is now being considered.  Is that reasonable?
Quotations below are also from Sir David Attenborough in recent years.

"I don't think whole populations are villainous, but Americans are just extraordinarily unaware of all kinds of things.  If you live in the middle of that vast continent, with apparently everything your heart could wish for just because you were born there, then why worry? [...]  If people lose knowledge, sympathy and understanding of the natural world, they're going to mistreat it and will not ask their politicians to care for it."  2005

"In the past, we didn't understand the effect of our actions. Unknowingly, we sowed the wind and now, literally, we are reaping the whirlwind. But we no longer have that excuse: now we do recognise the consequences of our behaviour. Now surely, we must act to reform it — individually and collectively, nationally and internationally — or we doom future generations to catastrophe."  2006

"The growth in human numbers is frightening. I've seen wildlife under mounting human pressure all over the world, and it's not just from human economy or technology. Behind every threat is the frightening explosion in human numbers. I've never seen a problem that wouldn't be easier to solve with fewer people – or harder, and ultimately impossible, with more."  2009

“We cannot continue to deny the problem. People have pushed aside the question of population sustainability and not considered it because it is too awkward, embarrassing and difficult. But we have to talk about it."  2012

“We are a plague on the Earth. It’s coming home to roost over the next 50 years or so. It’s not just climate change; it’s sheer space, places to grow food for this enormous horde. Either we limit our population growth or the natural world will do it for us, and the natural world is doing it for us right now.”  2013

Among the issues our children will face, population growth today exceeds support capacity, particularly food production and fresh water supply.  

World population has grown from 1.5 billion to 7.5 billion (quintupled) in my mother's lifetime.

It's been suggested that most of the world's problems would be solved if the population were cut in half, something that may be the inevitable result of current growth.   Most prophetic descriptions of the end-times suggest such collapse.  Economists, the UN, and others are beginning to agree.  Thoughts?
