摘　　要：人类作为生态系统中的重要功能单位,对地球环境产生了深远的影响。在社会和经济发展的过程中,随着人口数量的迅速增长,人们对自然资源不可持续的开发利用,使森林面积减少、土地退化、淡水资源紧缺、全球气温升高、严重破坏了生物多样性,使作物的产量明显下降,导致粮食安全问题日益严峻。介绍了粮食安全问题现状及其产生的主要原因,同时提出了应对粮食安全问题的举措,诸如大力发展绿色能源、减少温室气体排放、调整研究目标和方法、推广多样化种植摸式、提高粮食生产率等多种可持续发展的对策,共同应对粮食安全的挑战,实现人类与地球的和谐共生,旨在为应对粮食安全问题提供参考。Human is an important functional unit in the ecosystem and has producted great impact on the environment of the earth.With the rapid growth of population and unsustainable exploitation of natural resources during the process of social and economic development,the reduction of forest areas,land degradation,water scarcity,global temperature rise,and severe damage to biodiversity have occurred,leading to a significant decrease in crop yield and a growing food security problem.This paper introduced the current situation of food security issues and their main causes,also present various measures to address food security issues,such as promoting the development of green energy,reducing greenhouse gas emissions,adjusting research objectives and methods,advocating for diversified planting models,and improving food productivity.These sustainable development strategies aimed to collectively tackle the challenges of food security and achieve harmonious coexistence between humans and the earth,which was expected to provide reference for addressing food security issues.
