Last year, Americans spent more than $22 billion on chocolate. But the tasty treat comes at a far greater cost than this.

That's because farmers often cut down trees in the rainforest when they need more land to plant cacao trees. This contributes to climate (气候) change. In turn,climate change hurts cacao crops (产量). This puts chocolate at risk. But experts are developing solutions to ensure its future.

Chocolate comes mainly from the Cocoa Belt, a narrow piece of land along the equator. In the Cocoa Belt, it is hot and rainy. The conditions are perfect for growing cacao. But in recent years, climate change has a bad influence on the weather in the Cocoa Belt. As a result, cacao trees produce fewer beans. Climate change has also led to the spread of disease that harms trees.

In 2013, researchers studied the changing conditions in the Cocoa Belt. They said that by2050, it will be harder to grow cacao in 90% of places where it is now planted.But Christian Bunn of the International Center for Tropical Agriculture says chocolate won't disappear anytime soon. Plans to protect it are already taking shape.

One solution to the problem is cross—breeding (杂交). Scientists have developed new cacao trees that stand up to disease. Some even produce more cacao.

Weather stations will also help. Groups are building them in Africa. Around 70% of cacao is grown there. Information from the stations will help farmers know when to plant trees."Years back, farmers would follow farming rules that go with the seasons," Bunn said. "Those rules don't always apply anymore."

These fixes could help farmers grow more cacao on less land. That could help end the push to clear rainforest. That's good for chocolate, and a sweet deal for the planet."Everything has a side effect," Bunn said."We have to be smarter about our food."

Every New Year, many people make promises to themselves, only to see them fall by the wayside within a few months, weeks, or even days .However, 26— year old Luke Cameron is not among those people. After losing a close friend known for her generosity (慷慨) and died of cancer in 2013, the young man decided to do at least one good deed (好事) every day for 365 days and be has not missed one yet.

Cameron performed his first good deed on January 1st, 2014, with the simple act of greeting a waitress at a safe he visited. The next day he bought food and drinks for some homeless people. Cameron's good small deeds have been recorded in an online diary, like taking out the garbage for an elderly neighbor or spending a few hours helping a disabled lady pick out a dress tor a party. What's more, the young man has also spent close to £4,000 of his own money, buying gfts for children in need.

Cameron has created a series of some cards, which he has called"Cards for Kindness". Each card suggests a simple act of kindness — things like giving a stranger a hug or making peace with an enemy, which is to encourage others to perform good deeds.

Cameron's generosity has not gone unnoticed. To reward the young man as he nears the end of his journey，pizza chain Domino's recently awarded him a year's supply of free pizza. Not surprisingly, the big —hearted young man has decided to use the gift to hold special pizza days for charity. His kind deeds have also won him a competition for the job of"National Philanthropy (慈善事业) Manager".

Tyler was only in my senior class for a semester. He had been suspended (停学) many times in previous years because of his anger issues. When he entered my class, I thought the worst.

Tyler sat in the back row. Every time I talked to the class, I would ask students questions, calling them by name. Unfortunately, every time I called on Tyler, he would respond with a joke. If he got an answer wrong, he would become angry.

About a month into the year, I was still trying to connect with Tyler. I can usually get students involved in class discussions or at least have them sit quietly and attentively. However, Tyler was often loud and sometimes rude.

He had been in so much trouble over the years. He expected his teachers to know about his pasts: about how many times he had been sent to the office or suspended from school. I had found that these solutions were not very effective and that students would return from the office behaving worse than before.

One day, Tyler was talking over me while I was teaching. I stopped my lesson and said, "Tyler, why don't you join in our discussion instead of having one of your own?" With that, he got up from his chair, pushed it over and yelled something. I can't remember what he said other than that he included some impolite words. I sent Tyler straight to the office, and he received a week's suspension.

To this point, this was one of my worst teaching experiences. Tyler's anger was almost too much for me. The week Tyler was suspended from school was a wonderful time, and we got a lot accomplished as a class. However, the suspension week would soon come to an end, and I was fearful of his return.

On the day of Tyler's return, I stood at the door awaiting him.

A spark of surprise flashed across his face.
