Overview

We need to face the food requirements of a growing world population have to be satisfied and we also need to the face of increasing resource scarcities, such as water, energy and land and foods etc. with the situation further exacerbated by climate change. Thus, we need to focus on our reducing demand through food consumption behavioral changes and structural changes in food systems and food chains change. Due to some developed countries people often to choose to buy these foods to eat excessively e.g. cow meat and pig meat and drink excessive soft drinks, e.g. man-made color juice. So, these developed countries consumers will feel these excessive foods and soft drinks can be rubbish if these developed countries consumers often drink these man-made color juice and eat pig and cow meats often excessively. It seems who ought to change their diet behavior and food consumption to avoid to spend too much money to buy excessive foods and drinks and who often shall not decide to eat and drink them when who feel not hungry habitually . Hence, changing human diet habit is one important psychology factor to reduce water and foods shortage, due to the meats and juices can be reduced to be rubbish if human can learn how to control their diet habit to reduce to consume excessive meats and vegetables and rice and soft drinks etc. kind of foods and drinks. Then, I believe that food and water drinking numbers will be reduced too much in the future. Hence, different countries' governments need to educate whose people to know that why who will face foods and water scarcity possibly and to let who to know how the issue can be avoided to cause by the changing of their diet habit and consumption behavior. Teaching includes, such as let who to learn why resources scarcities are expected to reduce and defining food security concept, the need is for a better understanding of complexity of vegetable systems, the need to improve the diversity and response capacity of food systems to enhance resilience, the need to address both food consumption and production, knowledge generation and innovation through cross-sector approaches is essential and the need for agricultural knowledge and innovation systems that are fit for farming purpose. After developed countries' people are educated to let who to know why who need to reduce to consume excessive foods and soft drinks habitually to aim to avoid the chance of foods and water supply shortage will be occurred after 2050 year. On the other side, in the case of biodiversity, the loss of functional biodiversity destabilizes ecosystems and weakens their ability to deal with natural disasters or human induced stresses, such as pollution and climate change. Hence, scientists need to research how to reduce new diseases to cause foods and water pollution, even new diseases cause to influence human health. Due to unpredictable new diseases will be caused foods, fruits, vegetables etc. can't be grow easily, even cows, pigs, sheep etc. animals are not health to cause diseases to be died easily. Then, those new diseases will be decreases our foods supply numbers seriously. Resources scarcities are expected to define future food security. The predominant form of agriculture, food processing and retailing relies heavily on cheap inputs and the potential impact on this of long term resource scarcity trends has been largely overlooked.
