【正文】 research in 2017 revealing that eating similar foods led to people feeling emotionally closer to one another, Dr Woolley and Dr Fishbach wondered whether the way in which food was served also had a psychological effect. They theorized that, on the one hand, sharing food with other people might indicate food scarcity（短缺）and increase a feeling of petition. However, they also reasoned that it could instead lead people to bee more aware of others39。A選項的描述 糧食生產(chǎn)可導(dǎo)致約20%的人為造成的溫室氣體，而只使用了三分之一的無冰土地 正確，故選A。肥料徑流也導(dǎo)致了其他問題，例如伊利湖的藻類爆發(fā)以及墨西哥灣的死亡區(qū)域。impact nations, in general, you can see that, if you follow a nationally remended diet, despite the fact that these diets don39。It is estimated that following dietary guidelines can lead to decrease in more land use than in nutrient pollution.C.Some high173。schools program then that39。s team estimates that following the rules could result in as much as a 17 percent reduction in land use, a 21 percent reduction in nutrient pollution, and a 25 percent drop in agricultural greenhouse gas emissions.

The results are in the Proceedings of the National Academy of Sciences.t explicitly mention—environmental impacts, that you are going to have lower environmental impacts due to that.

While plants require water, sunlight and the right temperature to grow, it is widely believed they do not have senses in the way animals do. Gardeners such as Prince Charles who claim that talking to plants encourages them to grow have long been seen as a little silly. But scientists have discovered evidence which suggests the Royal may actually be right and they could be listening to him. Biologists at Tel Aviv University in Israel have found that flowers can act as a plant39。 However, Prof Hadany said a plant39。 A monthlong experiment conducted by the Royal Horticultural Society in 2009 found female voices appear to speed up the growth of tomatoes.
