The production of coffee beans is huge, profitable business, but unfortunately, full-sun production is taking over the industry and bringing about a lot of damage. The change in how coffee is grown from shade-grown production to full-sun production endangers the very existence of certain animals, and even disturbs the world’s ecological balance.
On a local level, the damage to the forests required by full-sun fields affects the area’s animals. The shade of the forest tree provides a home for birds and other species that depend on the trees’ flowers and fruits. Full-sun coffee growers destroy this forest home. As a result, many species are quickly dying out.
On a more global level, the destruction of the rainforest for full-sun coffee fields also threatens human life. Medical research often makes use of the forests’ plants and animal life, and the destruction of such species could prevent researchers from finding cures for certain diseases. In addition, new coffee-growing techniques are poisoning the water locally, and eventually the world’s groundwater.
Both locally and globally, the continued spread of full-sun coffee plantations could mean the destruction of the rainforest ecology. The loss of shade trees is already causing a slight change in the world’s climate, and studies show that the loss of oxygen-giving trees also leads to air pollution and global warming.
It is obvious that the way much coffee is grown affects many aspects of life, from the local environment to the global ecology. But consumers do have a choice. They can purchase shade-grown coffee whenever possible, although at a higher cost.

4 . They, stretching along the shore, swim quite lovely, looking for underwater greens to feed on. However, in these days, something is mixing with the sea grass that manatees(海牛)like to eat along Florida’s western coast. And it’s making them sick-even killing them.
It’s a poisonous form of algae, which is usually called “red tide” because of its color. Algae are plant-like organisms that live mainly in water. Most are harmless, but red tide is an exception. When it gets mixed in with the grass and the manatees eat it, they get so sick that they can’t even swim.
“They’re basically paralyzed(瘫痪的), and they become unconscious,” said Virginia Emonds, an animal care manager. Manatees are mammals and they need to surface often to breathe in air. If a manatee is paralyzed, it can’t swim and will drown.
As of Monday, the current red tide outbreak has killed at least 184 manatees since the beginning of this year. That has already beaten Florida’s record-high number for manatee deaths in a single year-and we still have nearly nine months to go!
The experts aren’t sure when the red tide outbreak will end. So many more manatees are in danger. The situation has gotten so desperate that Florida zoos have rescued at least a dozen manatees. You can find manatees anywhere from Brazil up to Florida-and throughout much of the Caribbean Sea.
In fact, the manatee is officially considered an endangered species. Thanks to the US government’s protection, Florida’s manatee population has grown to approximately 5,000 in recent years. But the red tide is threatening their survival. Some experts suspect that pollution from farms even might be fueling the red tide outbreak, because fertilizer that’s used on farms often winds up in water. And when that fertilized water runs off into the Gulf of Mexico, it makes things grow faster-just like on land.

Nuclear and renewables are seen as two key ways for governments to decarbonize(去碳), but the question of whether one is more effective for dealing with climate change
To find out, Benjamin Sovacool at the University of Sussex and his colleagues looked at carbon dioxide (CO2) emissions and GDP over 25 years. They found that in 117 countries that had been using renewables, CO2 emissions per capita(人均地)dropped from 0.69 tonnes(公吨)on average between 1990 and 2004 to 0.61 tonnes between 2000 and 2014 and
During the same periods, however, the 30 countries that had been using nuclear power largely stayed flat, shifting from an average 0.52 tonnes of Co2 emissions per capita to 0.51. The two groups of countries overlap because some fall into both. Renewables included wind, solar, hydroelectric, and biomass energy. “If you’re focusing on

Food delivery apps are changing the way we eat
It’s raining, it’s dinnertime, and the fridge is nearly empty. Years ago, we made do; today, we order food through our phones. Within twenty minutes, we get whatever it was we were craving, we’re warm and dry, and there’s not a single dish to wash afterward.

9 . Ranchers(农场主) and environmental advocates haven’t always seen eye to eye, but the differences between the two aren’t as extreme any more, as more and more ranchers have come around to the understanding that taking good care of the land supports both economic stability and environmental health.
“For some, ranching was pursued in the past with an emphasis on raising beef at the expense of everything else,” says Bill Bryan of the Montana—based Rural Landscape Institute in a recent Christian Science Monitor. “As a matter of necessity, the old way of ranching is giving way to a new pattern. Raising animals for the dinner table isn’t an activity that has to be at odds with the environment.”
According to the nonprofit World Wildlife Fund (WWF), grazing (放牧)—when done right—is key to maintaining biological diversity and ecosystem health across the Northern Great Plains, across 183-million-acre expanse of rangelands spanning five US states and two Canadian provinces.
This vast landscape evolved in harmony with large herbivores (食草动物), such as bison and elk, and must be grazed in order to remain healthy, reports WWF, which works with hundreds of ranchers across the region as part of its Sustainable Ranching Initiative. “Without grazing, woody vegetation, such as juniper and cedar creeps in and kills plants that threatened species, such as grassland birds, need to survive.”
Not surprisingly, many of the ranchers that are following in the forebears’ footsteps have been using what we now call “sustainable ranching practices” for decades already. One example is rotational (轮流的) grazing, that is moving cattle herds more frequently to different pastures(牧场), so they don’t overgraze any one particular patch of land.
A newer “best practice” involves depositing a quarter to half inch of cattle wastes on grazed land to kick-start the soil chemistry below while also absorbing significant amounts of methane (沼气)—the most potent greenhouse gas—before it can head for the atmosphere. This technique is now becoming more commonplace as today’s ranchers care about reducing their carbon footprints like no generation before them.

The problem of electronic waste
We have gradually come to realise that in two ways in particular, modern hi-tech can be bad for the planet. The first is its energy use; the worldwide scale of information technology is so enormous that electronics now produce fully two percent of global carbon emissions, which is about the same as the highly controversial emissions of aeroplanes. The other is the hardware, when it comes to the end of its natural life. This, increasingly, is pretty short. We have hardly noticed this important stream of waste, so much so that a Greenpeace report on the untraced and unreported e-waste two years ago referred to it as “the hidden flow”. We need to be aware of it.
The latest United Nations Environment Programme (UNEP) report estimates that worldwide, electronic waste is mounting by about 40 million tons a year. So what can we do about it?
The European Union has recognised the problem by adopting a key principle: producer responsibility. In other words, making it the duty of manufacturers of electronic goods to ensure their safe disposal at the end of their lives. In practice, an EU regulation now means that electronics dealers must either take back the equipment they sold you, or help to finance a network of drop-off points, such as public recycling sites. Its main feature is quite ambitious: it aims to deal with “everything with a plug”.
The new UN report suggests that all countries could do something about the problem with a change in design. Groups such as Greenpeace have led the way in putting pressure on major manufacturing companies to find substitutes for the toxic chemicals inside their products. Encouragingly, they have had some success in forcing them to develop non-poisonous alternatives to these. This may be the real way forward.
