    - The world population is currently in excess of 7.1 billion (possibly much more due to unaccounted statistics).

    - In 200AD, the world population was around 100 million.

    - It reached 1 billion by 1850.

    - It subsequently jumped to 2.5 billion by 1950.

    - Now, in about 60 years, it has now nearly tripled to over 7.1 billion human beings and rising. (Link: http://www.worldometers.info/world-population/)

    Now, if we actually took good care of the planet and its humans and distributed the resources effectively and managed damage, Earth is said to be able to manage to hold many tens of billions (it is well known that we could fit one billion people each a metre apart, into a field 32km square and so, enabling everybody in the world to fit easily into Yorkshire.)

    But clearly, the main issue is resources.

    Nevertheless, whilst the title asks if we should find a second home, there are of course numerous other measures to put into place.

    For example:

    - We should enthusiastically curb any further population growth (e.g. by discouraging having more than a certain amount of children - similar to the now dubious One Child Policy of China).

    - Encourage use of condoms in developing countries (particularly emphasising the folly of the Catholic Church).

    But clearly right now, the first point must be enthusiastically and rigorously put into action and the greatest threats to carrying out such actions are Abrahamic religions such as Islam and Christianity, the former encouraging high birth rates.

    The problem with a global one child policy is that we will be left with an ageing population which will affect the countries badly until they all die out, sp to speak, which is basically going to be a lifetime. We do need to look at gathering resources outside of Earth, but personally I believe that the population will be reduced significantly by an disease pandemic or war before this becomes an issue. But you are right, we can't keep this up.

    To deal with your points...

    1) Should we look for a new home? We already are, we have identified hundreds of planets with potentially viable star systems fairly close to us. Additionally we have already begun basic anti-matter research so potentially we could leave this planet within the century (being optimistic here). It is however far too expensive to Terra form anywhere in the solar system.

    2) Should we force a one child policy? No, we see a good correlation in most developed nations that they have below replacement birth levels. Additionally this is even occurring in some developing countries such as Iran (the birth rate has fallen from 7 to 1.6 - below that of the UK). The focus here should be on enhancing the development of these nations via trade and providing contraception for them.

    Finally to deal with your general message i think many people (especially the green lobby) are far too pessimistic...

    1) We already produce enough food for every person on the planet, the problem is one of distribution not production. Additionally meat requires ten times the resources of plants to grow so even before we consider genetically modified crops we already have room to increase production.

    2) We are on a planet full of water, either we can build desalinization plants or we can tunnel towards depressions and form inland lakes (Egypt has a potential one). Problem is cost not technology.

    3) We are on a planet with a diverse climate. By 2020 Scotland could be self-sufficient in energy mainly by wind and tidal. When you consider that even a national solar grid in Africa could provide a wealth of energy for the majority of Europe we see that the problem here is not technology but cost. This sidesteps the fact that nuclear fusion is on its way with successful tests.

    4) Lack of resources. It appears as if some companies believe space mining is viable and i am very interested in this endevour given Planetary Resources has the backing of the Google founders and James Cameron.

    I'm pretty optimistic, we are human and we have the potential to be brilliant.
