Please describe the Weak Signal (approx. 150 words)
Increased reliance on fewer favoured varieties of plant and animal foods increases risk of devastating effect of diseases (could be through genetic selection, GM or just market pressure). For example, with less varieties of apples/rice/wheat there is less diversity and so a larger proportion will be susceptible to any one disease or pest that now extinct species may have had natural resistance too. Same is true of farm animals.
