Drought
In many dry areas, droughts have made it difficult for farmers to grow their crops. From the southern USA to Australia to northern China, dry periods have been very destructive, leading to catastrophic results. Australia recently went through a seven-year dry period, which hit dairy farmers most severely, since their cows did not have enough grass to feed off. Drinking water and crop water were subsequently rationed. Many of these nations have tried cloud seeding with limited success.
