Feeding the world’s population is a big challenge, and it about to get bigger. Right now, a little more than 7.3 billion people share the planet. By 2050, some scientists, estimate the world’s population may reach 9 billion. However, the changing climate will probably make feeding this far greater number a very frightening task. That is the conclusion reached by some scientists.
Just three crops--wheat, rice and corn--provide more than two-thirds of the calories that people consume. Such crops, and a small number of other important crops, come from farming regions sometimes referred to as "breadbaskets". However, these areas often occupy a relatively small portion(部分) of the globe. Worse still, the breadbaskets are easily affected by bad weather. Events such as widespread flooding or extended heat wave can kill crops. That's especially true if the bad weather occurs when a crop is young, fruiting or approaching harvest.
Unfortunately, big crop failures in two or more breadbaskets could lead to what researchers call a "food shock". That means an overall shortage of food would occur. Extreme food shocks used to happen every century. Or to put it another way, that's only about once every four generations of humans. However, according to studies, as the climate warms, high and low temperatures become more extreme, and by 2050, food shocks could occur about once every 30 years. In other words, a person born in the middle of the current century might live through two or three extreme food shocks during their lifetime.
So what can people do to help avoid food shocks? Making agriculture efficient is one choice. But one of the most effective ways to fight against food shocks might be to cut down on food waste." If we could cut food waste in half, " said Seth Cook, a British environmental scientist, "we could feed an billion people. "

I never grasped the importance of conserving and protecting nature and wildlife, but five months was all it took to turn my indifference into a passion that has changed the track of my life.
Early last year, I was lost and troubled by an anxiety that crippled (削弱) my ability to do anything, even those I loved. I felt like a storm cloud hung over me. For almost a year I struggled on, constantly staring at this wall that faced me. My pursuit of perfection was the main root of this: I wanted to be the best at whatever I did, which obviously in life is not possible. My perfectionism has always been with me. My time in a small junior school made it easy for me to rise to the top. Upon entering a bigger senior school, though, my pursuit of perfection was far from accessible. Perfectionism in small amounts is brilliant, however in overwhelming doses it can be damaging.
One day, I attended a presentation by wildlife conservationist Grant Brown at my school. His presentation not only awed and inspired me, but also helped emerge an inner desire to make a difference in the world. Luckily, as a member of the Environmental Society, I was invited to join a pre-presentation dinner with him and that smaller setting allowed me to slowly build up my courage to speak one-on-one with him—an idea that had seemed completely impossible. This first contact was where my story began.
First, an application to join the Youth For Our Planet and UK Youth For Nature groups was sent around through my high school. I decided to submit my application, and soon I found myself a part of a growing global team of young people working to protect nature and creating climate solutions. Later, Brown invited me to attend the World Youth Wildlife Conference.
