写食物的演讲稿篇1
good morning, my dear teachers and my friends.
it is my great pleasure to stand here to have a speech, today i am going to talk about”food safety”.
?mention the food safety, people's hearts are unusual interest, concern. because with economic and social progress, economic globalization continues, people food culture diversity, food hygiene and safety
become much-talked-about hot topic. food diversification development, various additives renovates ceaselessly, emerging, trimethoxysilane cyanogen amine, sudan red, red meat fine, no root agent, each report let a person, soul-stirring each report related to the general public's heart.
food safety problems, the person's health would be threatened. although the food safety is social information asymmetry, but may be consumer heart default, considering our everyday eat food, think about the people around us, they also mostly agree "out of sight, out of mind" view. many consumers listen to media advertising, find out that problem, they knew that they again become victims. the body is his own, some poison is a lifetime all away, or even affect the next generation. their own health, who is responsible for wrong will care about you

different farming systems vary enormously in their reliance on mined phosphate. organic farms are more resilient to the coming phosphorus rock ‘shock’, as it can only be used as a supplement to nutrient recycling (including crop rotations, green manures, and composting), and not as a replacement. organic crops generally have a lower fertiliser requirement than non-organic crops, with a greater capacity to scavenge for nutrients through denser and deeper root systems.
2.changing what we eat
eating less meat can reduce the demand for mined phosphate. this is because vegetable-based production is more efficient in its use of phosphorus then livestock production. although different types of meat have different levels of mined phosphate demand depending on the farming system used to produce them. meat from livestock grazed on grassland that has not been fertilised with artificial fertilisers, will perform much better than meat from livestock grazed on fields that have been, or livestock fed on grain grown using artificial fertilizers
3,changing how we deal with human exreta
the report recommends a radical change in the way we treat human exreta and the need to abandon our current ‘flush-and-forget’ toilet systems in favour of ecological sanitation. the report also calls for a change to eu organic regulations to allow the use of human sewage – rich in ‘natural’ phosphate - on agricultural land to ensure phosphate levels are maintained. globally only 10% of human waste is returned to agricultural soils. urine alone contains more than 50% of the phosphorus excreted by humans.
let the good faith in our hearts, and the let the world fill with love thank you for your l
