4 . On numerous drives with my mom through my childhood, she would suddenly pull over the car to examine a flower by the side of the road or rescue a beetle from danger while I, in my late teens and early twenties, sat impatiently in the car.
Though Mother's Day follows Earth Day, for me, they have always been related to each other. My mom has been ''green'' since she became concerned about the environment. Part of this habit was born of thrift(节俭). Like her mother and her grandmother before her, mom saves glass jars, empty cheese containers and reuses her plastic bags.
Mom creates a kind of harmonious relationship with wildlife in her yard. She knows to pick the apples on her trees a little early to avoid the bears and that if she leaves the bird feeders out at night, it is likely that they will be knocked down by a family of raccoons(浣熊). Spiders that make their way into the house and are caught in juice glasses will be set loose in the garden.
I try to teach my children that looking out for the environment starts with being aware of the environment. On busy streets, we look for dandelions(蒲公英)to fly in the wind; we say hello to neighborhood cats and pick up plastic cups and paper bags. This teaching comes easily, I realize, because I was taught so well by example. Mom didn’t need to lecture; she didn't need to beat a drum to change the world. She simply slowed down enough to enjoy living in it and with that joy came mercy and an instinct(直觉)for protection.
I am slowing down and it isn't because of the weight of my nearly forty years on the planet, it is just out of my concern for the planet itself. I've begun to save glass jars and reuse packing envelopes. I pause in my daily tasks to watch the squirrels race each other in the trees above my house.
Last summer, I planted tomatoes in my yard. With the heat of August around me, I enjoyed my tomatoes while sitting on my low wall. I immediately wanted to share with my mom.

5 . There has, in recent years, been an outpouring of information about the impact of buildings on the natural environment. Information which explains and promotes green and sustainable construction design, strives to convince others of its efficacy (功效) and warns of the dangers of ignoring the issue. Seldom do these documents offer any advice to practitioners, such as those designing mechanical and electrical systems for a building, on how to use this knowledge on a practical level.
Although there are a good many advocates of “green” construction in the architectural industry, able to list enough reasons why buildings should be designed in a sustainable way, not to mention plenty of architectural firms with experience in green design, this is not enough to make green construction come into being. The driving force behind whether a building is constructed with minimal environmental impact lies with the owner of the building; that is, the person financing the project. If the owner considers green design unimportant, or of secondary importance, then more than likely, it will not be factored into the design.
The commissioning (委任) process plays a key role in ensuring the owner gets the building he wants, in terms of design, costs and risk. At the predesign stage, the owner’s objectives and expectations are discussed and documented. This gives a design team a solid foundation on which they can build their ideas. Owners who skip the commissioning process, or fail to take “green” issues into account when doing so, often come a cropper once their building is up and running. Materials and equipment are installed as planned, and, at first glance, appear to fulfil their purpose adequately. However, in time, the owner realizes that operational and maintenance costs are higher than necessary, and that the occupants are dissatisfied with the results. These factors in turn lead to higher ownership costs as well as increased environmental impact.
In some cases, an owner may be aware of the latest trends in sustainable building design. However, firms should not take it as read that the client already has an idea of how green he intends the structure to be. Indeed, this initial interaction between owner and firm is the ideal time for a designer to outline and promote the ways that green design can meet the client’s objectives, thus turning a project originally not destined for green design into a potential candidate.
Typically, when considering whether or not to adopt a green approach, an owner will ask about additional costs or return for investment. In a typical project, landscape architects, mechanical and electrical engineers do not become involved until a much later stage. However, in green design, they must be involved from the outset, since green design demands interaction between these disciplines. This increased cooperation clearly requires additional cost. However, there may be financial advantage for the client in choosing a greener design. There are examples of green designs which have demonstrated lower costs for long-term operation, ownership and even construction.

6 . Scientist， conservation organizations and government trying to stop the trend of extinction （灭绝） often focus on protected areas such as national parks and wildlife preserves. But with as many as million species（物种） at risk， this plan of action may not be enough to conserve wildlife.
Slowing the mass extinction that now appears to be underway will require more creative means of coexisting alongside wild plants and animals. A new study indicates the effectiveness of some such approaches by examining some lands managed by indigenous groups.
“ We show really strongly that， from a biodiversity standpoint in terms of species richness，indigenous － managed lands are at least comparable to protected areas， ” says biologist Richard Schuster of Carleton University. And in some places， they are better than parks and preserves －even though indigenous communities may use their lands’ resources by hunting or searching for food.
Schuster and his team analyzed more than 15，000 areas in Australia， Brazil and Canada. They found that the total diversity of wildlife was highest on lands either managed or co － managed by indigenous groups， while randomly selected areas with no formal protection were the least bio－diverse. For threatened species in particular， indigenous lands scored slightly higher than protected lands on overall species richness in Brazil and Canada， as well as higher for threatened animals in Australia.
Each country has a different geography， climate and history. Yet remarkably， Schuster says， the best indicator for species diversity is whether a given area was managed by an indigenous community. He pointed out that practices such as sustainable（可持续的） hunting， fishing and searching， as well as burning， are more likely to occur in such areas. Don Hankins， an ecologist at California State University，agrees. “ there’ s probably going to be more of a connection to the land， ” he says， “ and a use of the land for the things that are there， compared to a national park. ”
“ It’ s really important to listen to the people who live on the land and have them drive the stewardship efforts going forward， ” Schuster says， adding that partnering with indigenous communities may enable the world’ s countries to better meet a wide range of conservation goals： “ We really need all the help we can get as a global community to prevent species extinction that we’ re facing right now. ”

9 . Is Your Diet Destroying the Environment?
A vegetarian diet is often praised for its health benefits. Studies have shown that vegetarians usually have lower levels of heart disease and a lower risk of diabetes than people who eat meat. What most people are less aware of, however, are the effects that a vegetarian diet can have on the environment.
Researchers from the Union of Concerned Scientists in the US recently studied how consumer behavior affects the environment. The study showed that meat consumption is one of the main ways that humans can damage the environment, second only to the use of motor vehicle.
Then, how can eating meat have a negative effect on the environment? For a start, all farm animals such as cows, pigs, and sheep give off methane (沼气) gas by expelling (排出) wind from their bodies. One cow can produce up to 60 liters of methane each day. Methane gas is the second most common greenhouse gas after carbon dioxide. Many environmental experts now believe that it is more responsible for global warming than carbon dioxide. It is estimated that 25% of all methane released into the atmosphere comes from farm animals.
Another way that meat production affects the environment is through the use of water and land. 2,500 gallons of water are needed to produce one pound of beef, whereas 20 gallons of water are needed to produce one pound of wheat. One acre of farmland used for crop production can produce 40,000 pounds of potatoes, 30,000 pounds of carrots, or 50,000 pounds of tomatoes.
Many people now see the benefits of switching to a vegetarian diet, not just for health reasons, but also because it plays a vital role in protecting the environment. However, some nutritionists advise against switching to a totally strict vegetarian, or vegan diet. They believe a vegan diet, which excludes all products from animal sources, such as cheese, eggs, and milk, can be short of many necessary vitamins and minerals our bodies need.
Today, many people know it’s important to take better care of their bodies and to use the earth’s resources more efficiently. As this understanding spreads, more people may realize that to help the environment and for the human race to survive, more of us will need to become vegetarians.

10 . A 2018 report found that food waste would increase by a third to 2. 1billion tons by 2030. Beyond the cost of the waste itself，thrown-away food generates a gas that contributes to climate change.
Home delivery meal kits(盒)can reduce food waste by more than two-thirds，but suppliers need to switch to reusable packaging to make them environmentally friendly.
Tailor-made meal kits cut waste by providing people with precise amounts of fresh ingredients(烹饪原料)for chosen recipes，meaning leftovers are minimized. But while the delivery services score well on reducing food waste，buying the same food ingredients from the supermarket almost always saves energy overall simply because meal kits use so much single-use packaging. The good news is that if people have meals that are tailored for consumption，they won’t overbuy and have less food waste. They fine-tune the amount of food to what they will actually eat.
Meal kits can reduce transport emissions(排放)if people go to the supermarket less frequently. If people only go and buy such goods as soap and toilet paper，they may only have to visit once every couple of months. A delivery truck can carry meals for a lot of people in the neighborhood. So dozens of car trips might be replaced with one truck trip.
However，study found that even if delivery meal kits reduced food waste to zero，they would still use up more energy overall than buying the same food from the supermarket unless the energy used for the meal kit packaging was cut by a fifth. The packaging is a killer if it’s single-use and thrown away，which can make all the environmental benefits lost. But if the packaging can be reused，if it’s glass bottles，like in the old days，we can get some benefits.
