This is a fairly radical view point and one I do not subscribe to personally but it does pose some interesting questions.

Without doubt the majority of parents view their children as a wonderful blessing and joy. However there is small group of individuals who subscribe to the theory that children are in fact a threat to the future of our planet. Their view is based on the idea that each additional human being uses more of the planets limited resources such as food, water, fossil fuels and  trees and contributes additional greenhouse gases, rubbish and pollution. 

A slightly less controversial view point is that if we limited the number of children each family has then we also limit the negative impact on population growth and ultimately produce individuals that contribute to our the development of ecologically sustainable technologies and projects.

Passive solar buildings aim to maintain interior thermal comfort throughout the sun''s daily and annual cycles whilst reducing the requirement for active heating and cooling systems. Passive solar building design is one part of green building design, and does not include active systems such as mechanical ventilation or photovoltaics, nor does it include life cycle analysis.

Application for Greywater

Irrigation, Indoor reuse, Extreme living conditions, Heat reclamation

Greywater typically breaks down faster than blackwater and has much less nitrogen and phosphorus. However, all greywater must be assumed to have some blackwater-type components, including pathogens of various sorts. Greywater should be applied below the soil surface where possible (e.g. in mulch filled trenches) and not sprayed, as there is a danger of inhaling the water as an aerosol.

However, long term research on greywater use on soil has not yet been done and it is possible that there may be negative impacts on soil productivity. If you are concerned about this, avoid using laundry powders; these often contain high levels of salt as a bulking agent, and this has the same effect on your soil as a drought.
