World hunger related to climate and water resources
The world population is growing at rates higher than yields on fields particularly in developing countries can produce and it is estimated that in the coming decades, this relationship could be particularly unfavorable in part for cause of the climate changes which make the land less productive, and in part for cause of scarce water resources and parasites more aggressive, favored by drought in some areas that aggravates the situation and makes it more difficult all the farming practices. Maintain the biodiversity and protect the environment appears to be useful to a healthy balance between growth and human food production, but for example there is the problem related to the use of pesticides and all chemicals and technology used in the modern agriculture, whereas the population of certain species of animals and insects (essential for crops such as bees) in particular areas seems to be declining.
