From years ago I warned through your columns about world population increasing. At that time the figure was seven billion rising to 10 billion in 20 years.

I would suggest to a degree already the attempts to get into Europe by people are partially due to over population in their own countries.

I said at the time it is good to act on global warming but why is little or nothing being done on over population?

What is needed is massive contraception throughout the world. Imagine the situation in 2035 with a population of 10 billion.
