Then in the end the top predators get a even larger amount because they are consuming 3 trophic levels of pollutants that are getting more concentrated each time.


They are like sponges that storesnowmelt and rainfall, and release it gradually.

Once again, acid rain is the biggest threat to the deciduous forest.

The  is characterized by everything that could be expected of the ionizing the atmosphere.

The concentration of carbon dioxide in the atmosphere has increased more in the northern hemisphere where more fossil fuel burning occurs. Since the Industrial Revolution the concentration globally has increased by about 40.

Mineral nutrients are essential for the growth and development of plants and microorganisms, and are important factors in plant-disease interactions. How each nutrient affects a plant's response to disease, whether positively or negatively, is unique to each plant-disease complex. This publication briefly summarizes plant mineral nutrition and what is known about how different nutrients affect different types of plant diseases (fungal, bacterial, viral, and soilborne) and pests.

The United States is the most industrialized nation on Earth.

Buildings with centralized heating and airconditioning remove negative ions and add positive ions.

Martin G, Leivar P, Ludevid D, et al. (2016) Phytochrome and retrograde signalling pathways converge to antagonistically regulate a light‐induced transcriptional network. Nature Communications 7: 11431.

The world at large demonstrates the impact of what might otherwise be considered trivial:"Epidemiological data indicate that increased small positive air ionization due to changingweather conditions is associated with increases in industrial and automobile accidents, suicide,and crime, as well as depression, irritability, and interference with central nervous systemfunction."Positive ions are known to create or trigger other phenomena.

In addition, air brushing past a metalsurface or through a pipe also creates positive ions.

Food productionmust increase just to keep up withpopulation growth!

It is not widely recognized because of the intensification of croppingpatterns and the plowing of marginal land that leads to excessive erosion over the long run canlead to production gains in the short run, creating the illusion of progress and a false senseof food security."It is quite ridiculous for us to continue with such a devastating practice as world hunger andpopulations grow.

Effects Of Plant Pathogens On Plant Physiological Functions

The entire problem can be summed-up by recognizing that it takes500 to 1,000 years to develop a mere 2.5 centimeters (one inch) of topsoil, empires havecollapsed throughout history partly due to erosion, and recently, since 1914, more topsoil hasbeen lost than in all of previous history!
