Pesquisadora sobre fogo na Amazônia explica real situação da floresta.


A pesquisadora sênior da Universidade de Oxford, Dra. Erika Berenguer, é uma das maiores referências sobre fogo em florestas tropicais do mundo. Ela relata que um “aspecto importante a ser considerado é que incêndios na floresta amazônica não ocorrem de maneira natural – eles precisam de uma fonte de ignição antrópica. Ao contrário de outros ecossistemas, como o Cerrado, a Amazônia não evoluiu com o fogo e esse não faz parte de sua dinâmica. Isso significa que quando a Amazônia pega fogo, uma parte imensa de suas árvores morrem, porque elas não têm nenhum tipo de proteção ao fogo. Ao morrerem, essas árvores então se decompõem liberando para a atmosfera todo o carbono que elas armazenavam, contribuindo assim para as mudanças climáticas. O problema nisso é que a Amazônia armazena muito carbono nas suas árvores - a floresta inteira estoca o equivalente a 100 anos de emissões de CO2dos EUA. Então queimar a floresta significa colocar muito CO2de volta na atmosfera.”

Is it really possible that plant-based foods such as the Impossible Whopper are healthful?


ByCara Rosenbloom September9, 2019


With many American consumers interested in reducing their consumption of animal products without becoming vegetarian or vegan, the food industry has come up with a new craze: plant-based. Look around your grocery store, and you’ll see a growing number of dairy, egg and meat substitutes bearing this label.

But the industry has taken liberties with the definition of “plant-based.” Rather than focusing on whole foods such as vegetables, fruits, legumes and nuts, which is what health professionals mean when they recommend “plant-based eating,” food manufacturers are developing ultra-processed burgers out of pea or soy protein, methylcellulose and maltodextrin, and liquid “eggs” out of mung bean protein isolate and gellan gum. Then they crown this ultra-processed food with an undeserved health halo.

(…)

Plant-based ultra-processed products such as these are formulated to taste like the real deal. Thus, consumers can feel virtuous or principled for choosing plants over meat without sacrificing too much flavor. But is there any value to plant-based products that have been crushed, extruded and shaped into facsimiles of the foods they are replacing? Let’s look at that question through several lenses — considering nutrients, how processed the food is and how producing the food affects the planet.

When I was in nutrition school, the health value of food was mostly calculated based on the presence of desirable nutrients, such as fiber and vitamins, and on the absence of negative nutrients, such as sodium or trans fat. If you compare ultra-processed plant-based foods and similar animal-based foods solely on their nutrients, you’ll find they are roughly the same.

Plant-based foods are purposely formulated to mimic animal-based foods, so plant-based milk is enriched with calcium and vitamin D to mimic cow’s milk, while veggie burgers are rich in protein and made with iron and zinc to imitate beef. But they aren’t always made to reduce the presence of less-healthy nutrients. Sometimes, the processed plant-based food will have more sodium than the processed animal-based food, and sometimes the animal food will be higher in calories or saturated fat.

(…)

Using the term “plant-based” on fast food labels is just another attempt by marketers to re-brand junk food. True plant-based eating doesn’t mean opting for an Impossible Whopper in the drive-through or scrambling up some 15-ingredient “egg alternative.” It means a diet that includes nourishing options such as black beans, broccoli and brown rice. We’re always looking for some magical way to eat junky food and achieve health. Don’t be fooled by this plant-based pretense.

Leia o fragmento de reportagem.


O presidente dos Estados Unidos, Donald Trump, designou oficialmente o Brasil como aliado militar preferencial do país fora da Organização do Tratado do Atlântico Norte (OTAN).

[...] O status dá ao Brasil o direito de tornar-se comprador preferencial de equipamentos e tecnologias militares dos Estados Unidos, além de participar de leilões organizados pelo Pentágono. A medida também abre caminho para a colaboração no desenvolvimento de soluções de defesa e o aumento dos intercâmbios militares e a realização de manobras conjuntas entre as Forças Armadas dos dois países.

How to Make Friends While Traveling Solo

Even in the best cases, traveling alone can get lonely. Here’s how to connect safely with the people you meet along the way.

By Aric Jenkins April 16, 2019

Experiencing another culture on your own terms, at your own pace, with a budget of your own choosing can be an incredibly rewarding and insightful adventure. But while some may find such a journey liberating, others might worry about safety or a period of solitude in a strange, unfamiliar place. Humans, after all, are social animals.
Prospective solo travelers should know that, despite its label, solo travel does not have to mean you’re alone all the time. There are local communities to safely interact with as well as fellow globe-trotters in a similar position.
A 2016 report from travel research company Phocuswright found that a whopping 72 percent of hostel guests in the United States were traveling alone. Airbnb saw similar a trend in its data, with cities like Ho Chi Minh City, Cologne, and Johannesburg experiencing more than a 130 percent increase in individual bookings in 2016.
With solo traveling growing in popularity, it’s clear there are options to socialize with other travelers — it’s just a matter of putting yourself in the right position to do so. Here are some tactics you can use to meet and befriend people abroad, from tried-and-true methods to innovative new apps and technology.
Go on ‘free’ walking tours
The word free is in quotations because, assuming your tour guide is at least half-decent, you should tip them at the end (many earn the majorityof their income on commission). But these walking tours can be worth every penny. Not only will the guide give you an informed and hopefully entertaining view of the locale, but you’ll have a chance to interact with other tourists and possibly come away with a new friend.
(…)
Use Airbnb to go on unique experiences hosted by locals
Airbnb may be known more for its lodging arrangements, but it also wants to give you something to do at your destination. Airbnb Experiences connects travelers with local guides who lead guests on paid activities ranging from city tours to bar crawls and hobby and skill classes. Launched in late 2016, Experiences quickly became a popularfeature.
Connect with like-minded explorers on social travel apps
Prefer to cut out the middleman and connect directly with other travelers? Try your hand at the crop of social networking apps specifically designed for travel. Travello, free on iOS and Android, allows you to discover other travelersnearby, match itineraries for planned trips and join groups based on similar interests. You can also create a feed by posting photos and updates.
(…)
Stay in hostels
In a world of hospitable hotels and authentic Airbnbs, why do travelers elect to stay in hostels? Two reasons, really: Hostels are cheap and sociable. You’ll find college-esque dormitories with common lounge rooms and kitchens, and sometimes a bar or cafe.
It’s an idealenvironmentto meet other travelers, and hostel staffs are well aware of this — some will lead city tours or pub crawls designed to foster interaction between hostel mates. Others might host game nights in the common room or arrange family dinners.

They rose up like men. We saw them. Like men they stood.

We shouldn’t have been anywhere near that place. Like most farmland outside Lotus, Georgia, this here one had plenty scary warning signs. The threats hung from wire mesh fences with wooden stakes every fifty or so feet. But when we saw a crawl space that some animal had dug—a coyote maybe, or a coon dog—we couldn’t resist. Just kids we were.The grass was shoulder high for her and waist high for me so, looking out for snakes, we crawled through it on our bellies.The reward was worth the harm grass juice and clouds of gnats did to our eyes, because there right in front of us, about fifty yards off, they stood like men. Their raised hooves crashing and striking, their manes tossing back from wild white eyes. They bit each other like dogs but when they stood, reared up on their hind legs, their forelegs around the withers of the other, we held our breath in wonder. One was rust-colored, the other deep black, both sunny with sweat. The neighs were not as frightening as the silence following a kick of hind legs into the lifted lips of the opponent. Nearby, colts and mares, indifferent, nibbled grass or looked away. Then it stopped. The rust-colored one dropped his head and pawed the ground while the winner loped off in an arc, nudging the mares before him.

As we elbowed back through the grass looking for the dug-out place, avoiding the line of parked trucks beyond, we lost our way. Although it took forever to re-sight the fence, neither of us panicked until we heard voices, urgent but low. Igrabbedher arm and put a finger to my lips. Never lifting our heads, just peeping through the grass, we saw them pull a body from a wheelbarrow and throw it into a hole already waiting. One foot stuck up over the edge andquivered, as though it could get out, as though with a little effort it could break through the dirt being shoveled in. We could not see the faces of the men doing the burying, only their trousers; but we saw the edge of a spade drive the jerking foot down to join the rest of itself. When she saw that black foot with its creamy pink and mud-streaked sole beingwhackedinto the grave, her whole body began to shake. I hugged her shoulders tight and tried to pull her trembling into my own bones because, as a brother four years older, I thought I could handle it. The men were long gone and the moon was a cantaloupe by the time we felt safe enough to disturb even one blade of grass and move on our stomachs, searching for the scooped-out part under the fence. When we got home we expected to be whipped or at leastscoldedfor stayingout so late, but the grown-ups did not notice us. Some disturbance had their attention.

Since you’re set on telling my story, whatever you think and whatever you write down, know this: I really forgot about the burial. I only remembered the horses. They were so beautiful. So brutal. And they stood like men.
