The distribution of pollutants is significantly influenced by weather patterns and variability along with the spatial patterns of emissions.

Set-size effects in visual search may be due to 1 or more of 3 factors: sensory processes such as lateral masking between stimuli, attentional process limiting the perception of individual stimuli, or attentional processes affecting the decision rules for combining information from multiple stimuli. These possibilities were evaluated in tasks such as searching for a longer line among shorter lines. To evaluate sensory contributions, display set-size effects were compared with cuing conditions that held sensory phenomena constant. Similar effects for the display and cue manipulations suggested that sensory processes contributed little under the conditions of this experiment. To evaluate the contribution of decision processes, the set-size effects were modeled with signal detection theory. In these models, a decision effect alone was sufficient to predict the set-size effects without any attentional limitation due to perception.

So what you end up with is a completely depleted soil and food that has no particular food value anymore and if you wanted to put it back.

The strength of Greek agriculture is reviewed. Because of low wages, labour intensive products are the most promising.
