The proportion of younger, working adults will be smaller, and governments will therefore receive less money in taxes in relation to the size of the population.
In other words, an ageing population will mean a greater tax burden for working adults. Further pressures will include a rise in the demand for healthcare, and the fact young adults will increasingly have to look after their elderly relatives.
Finally, money from national budgets will need to be taken from other areas and spent on vital healthcare, accommodation and transport facilities for the rising numbers of older citizens.
Firstly, any new situation that a person encounters can be an opportunity to learn and grow as a person. A new job, for instance, might present challenges that push the person to adapt, acquire new knowledge, or add to their skill set.
The core subjects in most primary schools are the mother tongue language, mathematics and science, and it can be argued that lessons in a new language take valuable study time away from these key disciplines, as well as causing confusion in the young learners.
While I tend towards the viewpoint that animal testing is morally wrong, I would have to support a limited amount of animal experimentation for the development of medicines.
Opponents of such research argue that humans have no right to subject animals to this kind of trauma, and that the lives of all creatures should be respected. They believe that the benefits to humans do not justify the suffering caused, and that scientists should use alternative methods of research.
Supporters of the use of animals in medical research believe that a certain amount of suffering on the part of mice or rats can be justified if human lives are saved.
Personally, I agree with the banning of animal testing for non-medical products, but I feel that it may be a necessary evil where new drugs and medical procedures are concerned.
In conclusion, it seems to me that it would be wrong to ban testing on animals for vital medical research until equally effective alternatives have been developed.
These artworks represent culture, heritage and history. They serve to educate people about the city, and act as landmarks or talking points for visitors and tourists.
Governments and local councils should pay creative artists to produce this kind of art, because without their funding our cities would be much less interesting and attractive.
These public services are vital for a country to function properly, whereas the work of creative artists, even in public places, is a luxury.
