Human overpopulation

The Mother of most problems in the Earth are due to Human overpopulation. It would be beneficial to the world to decline the population instead of letting it to increase freely. Vatican and Pope should change their attitudes to favor birth control with the use of contraceptives. It´s a great joke of Vatican to say that they can not approve the use of condoms because they may break during the intercourse and that the e-pills may harm the person using them. More countries should change their policies to favor smaller families.

Desalinating sea water

“Salt water is desalinated to produce fresh water suitable for human consumption or irrigation. One potential byproduct of desalination is salt. Desalination is used on many seagoing ships and submarines. Most of the modern interest in desalination is focused on developing cost-effective ways of providing fresh water for human use. Along with recycled wastewater, this is one of the few rainfall-independent water sources.

Due to relatively high energy consumption, the costs of desalinating sea water are generally higher than the alternatives (fresh water from rivers or groundwater, water recycling and water conservation), but alternatives are not always available.”
