It must be recognised that overpopulation is the most serious current threat to the country.
The world is overpopulated. Global warming is the result of there being too many people not a few of them driving 4x4s.
Any couple who has more than 2 children are selfishly voting for massive population increase and hence massive increases in energy consumption. It is not an excuse to say the average is less, a third child equals 50% increase.
A target should be set for population reduction by rewarding those with 1 or fewer children and penalising the rabbits. Reduction by 5 million every 10 years would be sensible until a total of about 40 million is reached.
There would be huge financial benefits with reduced medical, then school costs, then housing costs and elimination of unemployment.
