1 . Warm-blooded species are evolving (进化) to have larger beaks, legs and ears to regulate body temperature as the planet warms up, new study suggests. The scientists behind the study warn the physiological changes do not mean animals are coping with climate change. If animals fail to control their body temperature, they can overheat and die.

Some animals in warmer climates have historically evolved to have larger beaks or ears to get rid of heat more easily. A larger wing, ear or beak relative to body size gives smaller animals a greater surface area to lose excess heat. Several species of Australian parrot have shown a 4-10% increase in size since 1871, which correlates with the rising summer temperatures over the years, the study says.

The scientists do say it’s hard to put the climate as the only cause of shapeshifting, but that other examples of species changing show the effect of heat. Wood mice are evolving to have longer nails, masked shrews are getting longer tails and legs, and bats in warm climates have bigger wings. The study suggests that shapeshiting is likely to continue as the climate becomes warmer because higher temperatures will influence the demand on animals to regulate their body temperature.

“Shapeshifting does not mean that animals are coping with climate change and that all is fine,” Sara says. “It just means they are evolving to survive it, but we re not sure what the other ecological consequences of these changes are, or that all species are capable of changing and surviving. The climate change that we have created is heaping a whole lot of pressure on them, and while some species will adapt, others will not.”

2 . It’s no surprise that wasting things is a nightmare for the environment — everything that we eat, wear, and consume takes up natural resources.When it comes to food waste, the environment has a double whammy — water, packaging,transportation,and agricultural resources get used up, and leftover sandwich or expired (过期的) broccoli you bought in hopes of healthy eating releases greenhouse gases as it decomposes in a landfill.

A new study from the UN Environment Program has found that a fair amount of food may never reach our mouth. Some get lost in production process, but it is mostly households that are to blame: the major waste results from our kitchen. 11 percent of the food in our fridges ends up in the trash, compared to a mere 2 and 5 percent respectively, from grocery stores and fast-food restaurants. These data madden almost half of the world’s population who are still struggling for healthy food. But surprisingly, the new study found that even less-developed countries are guilty of astonishing food waste, which is previously being thought of only as a rich-nation issue.

So what can we do? Something crucial is being more considered and prepared when going to the grocery store. Make a list of meals you want to cook, and then only buy fresh produce that you will 100 percent be eating in the next few days.

Societally, enhancing education on food preservation, food recycling and composting (堆肥), and pushing companies to sell smaller quantities food for one or two persons could all play a helpful role in bringing down the massive pile of food waste, says Edward Jaenicke, a professor of agricultural economics.

While some climate change related issues seem above our individual choices to solve, like the sea level rise,food waste is something we can actually make an impact on, by shopping smart, learning how to compost, and even getting creative with ingredients in the kitchen.We can actually make a difference by making some efforts or good choices or even changes in life.
