If our bodies actually suffer from eating too much sugar, then why do we like it? And why don 't we have such a strong eager for food like, say, broccoli (西兰花)，which is a great source of Vitamin C,Vitamin K iron, all things our body actually needs? If it's so bad for us, then why does sugar taste so good? There are hundreds of journal articles trying to answer that very question. Let' s take a look at what they' ve come up with.
Studies have shown that the love children have for sugar may be born with. In other words, kids may have a built-in love of all things sweet. The preference for sweet foods is found to be already evident in newborns, who prefer sweeter formulas (配方). It also seems to be shared by children globally across cultures and climates. There’s further evidence that kids’ taste buds (味蕾) are more sensitive to bitter-tasting foods, further pushing them to reach for the sweets. One study showed that adults tend to maximize their sugar preference at about the level of sugar in a can of soda, but older children still liked drinks that were twice as sweet. The scientists couldn't find a limit to the concentration of sugar younger children preferred. It turms out that the kids still liked the sugary drink even past the point where there was too much sugar to be dissolved (溶解) in water anymore.
Sugar gets a bad fame, but it isn't all bad. Sugar provides our bodies with calories, which we can then change into energy. Children, in particular, need this energy to fuel their rapid growth. Sugar also helps us store fat, which can be drawn on later if needed. Our body knows to pursue the things it needs as two way of signaling our brain to start eating what we’re missing.
As a vegetarian (素食主义者)，I know that when I start thinking about stealing the peanut butter sandwich that's been floating around in my kid' s backpack, it' s probably not because the sandwich is so delicious. It' s more likely that I haven't gotten enough protein for the day.

One of the most critical roles forests play is relieving climate change. Trees suck enormous amounts of carbon dioxide out of the air and fix the carbon in their wood and the soil. A recent study found that planting new trees over an area the size of the US could suck away two thirds of all the carbon dioxide discharge that humans have pumped into the atmosphere.
“Without animals, it is harder for forests to absorb carbon, as tree species (种类) important for protecting the climate could be lost without animals", Susanne Winter, a program director said at the WWF.
In Africa, many of the tree species that absorb the most carbon rely on large birds and primates (灵长类动物) to eat their fruits and spread their large seeds, according to the report. Without them, those trees would have difficulty reproducing and forests would lose their best carbon-storing trees.
“Forests are our greatest natural ally in the fight against global warming, ”Winter said.“If we want to hold back the worldwide decline in biodiversity and prevent the climate crisis,s we need to protect the forests and the species living there.
Forests also filter (过滤) water-- as water makes its way to lakes or groundwater reserves, the roots and soil separate it from deposits and pollution that it collects along the way. What' s more, forests regulate the global water cycle, since trees' leaves, branches, and roots store or send out water vapor.
Climate models show that forest-cutting down in Central Africa could lead to a 15% drop in rainfall in the US Midwest, and Amazon deforestation (森林滥伐) could cut Texas rainfall by 25%.
Humans also get food, wood, and medicine from the abundance of plants and animals in forests. Worldwide, 1.6 billion people rely on forests for their livings, according to the United Nations. About 300 million people live in forests, according to WWF.

In a world facing increasing conflict and instability, a Chinese Canadian is sending messages of love and peace through his artwork.
William Ho, 60, who arrived in Canada from Hong Kong 42 years ago, teaches Chinese brush-painting near Toronto. The United Nations invited Ho to exhibit his art and his masterpiece at its headquarters in New York in 2006, and he then became a UN global partner. Ho has been doing Chinese art and Chinese brush-painting for more than 50 years and teaching for over 30. He has more than 3, 000 students from around the world.
“I actually started in Western art when I was younger, working in pencil drawing, oil painting, water color, etc. However, after I met Chinese brush-painting a couple of years later, my eyes and mind were enlightened,”Ho recalled.

The people of the world and Mother Nature are saying no to the greedy. In fact, the whole world cannot afford these types of demands. We as a global family wouldn' t allow this to happen."Ho said. Contrary to greed, Chinese culture believes that“less is more'”.
“Chinese culture has been enlightening the world through our art, literature, philosophy, medicine, technologies in astronomy, navigation and four great inventions,”Ho said.
