The problem of water and sanitation
19
Nov
Although the planet has plenty of water, the water problem is
not negligible and what directly affects the planet, especially the poor and those who live in regions without basic sanitation, is the problem of drinking water, and therein lies the serious problem of contamination by agricultural activities.
Thus, it is necessary, together with the urgent problem of sustainable water management, to think about sustainable development in three dimensions: social, economic and environmental, even those who affirm public policies for this do not accept the reduction of profitable and polluting economic activities.
Studies show that the main causes, about 70%, are due to poor land use in agriculture (pesticides, river silting, intensive monoculture, etc.), followed by industry pollution 20%, domestic use 7% and losses 3% (see the figure above).
Because it was from biology and ecosystems that the ideas of complexity came, this is the sector most sensitive to small attitudes that can and should change the planet in the future, collect polluting waste, do selective collection and even reuse rainwater and using solar energy are attitudes that we can take individually and will be beneficial as a whole, see that complexity can involve simple ideas to be practiced.
The education of the new generations should therefore be the responsibility of everyone, the government, schools and families, small habits inserted in everyday life can transform a huge number of situations in scale, an effect known in complexity as the “butterfly effect”, the flapping of the butterfly wing can influence the climate, and deforestation and neglect of nature has a negative effect on the climate.
Research on planets where there may be life has as its first item the presence of water, and providing drinking water is therefore the first attitude in defense of life.
