Read the text to answer the question from.

It happens that the publication of this edition of the Oxford Advanced Learner’s Dictionary comes 250 years after the appearance of the first comprehensive dictionary of the English language, compiled by Samuel Johnson. Much has changed since then. The English that Johnson described in 1755 was relatively well defined, still essentially the national property of the British. Since then, it has dispersed and diversified, has been adopted and adapted as an international means of communication by communities all over the globe. English is now the name given to an immensely diverse variety of different usages. This obviously poses a problem of selection for the dictionary maker: which words are to be included in a dictionary, and thus granted recognition as more centrally or essentially English than the words that are left out?

Johnson did not have to deal with such diversity, but he too was exercised with this question. In his Plan of an English Dictionary, published in 1747, he considers which words it is proper to include in his dictionary; whether ‘terms of particular professions’, for example, were eligible, particularly since many of them had been derived from other languages. ‘Of such words,’ he says, ‘all are not equally to be considered as parts of our language, for some of them are naturalized and incorporated, but others still continue aliens...’. Which words are deemed to be sufficiently naturalized or incorporated to count as ‘parts of our language’, ‘real’ or proper English, and thus worthy of inclusion in a dictionary of the language, remains, of course, a controversial matter. Interestingly enough, even for Johnson the status of a word in the language was not the only, nor indeed the most important consideration. For being alien did not itself disqualify words from inclusion; in a remark which has considerable current resonance he adds: ‘some seem necessary to be retained, because the purchaser of the dictionary will expect to find them’. And, crucially, the expectations that people have of a dictionary are based on what they want to use it for. What Johnson says of his own dictionary would apply very aptly to The Oxford Advanced Learner’s Dictionary (OALD): ‘The value of a work must be estimated by its use: It is not enough that a dictionary delights the critic, unless at the same time it instructs the learner...’.

Re-Planting a Forest, One Drone at a Time

That funny little buzz you hear in the forest may not just be the hum of summer insects. In the near future it could be a small fleet of drones, coming to replant and restore forests that have been stripped of trees by industrial-scale deforestation. It’s all part of an ambitious plan by BioCarbon Engineering, a U.K.-based startup on a global mission to battle widespread clear-cutting, which strips more than 26 billion trees off the planet each year. CEO Lauren Fletcher, who spent 20 years as an engineer with NASA, says the only way to fight industrial-scale deforestation is with industrial-scale reforestation. Their idea: plant 1 billion trees a year. The first targets are in South Africa and the Amazonian jungles, both of which have suffered from widespread forest eradication.

BioCarbon’s reforestation scheme is simple and efficient. Here’s a quick look at how it plans to deploy its drone fleet:

1 Do a 3-D aerial survey. First, drones are sent to fly over a potential planting zone, snapping photos that create 3-D maps of the area to be reforested. The number of drones will vary depending up on the size of the seeding.

2 Create a seeding plan. Once all that terrain data has been analyzed, it then generates a seeding pattern that best suits the terrain.

3 Load the seed pods. The drones, which are equipped with guidance and control software, carry pressurized canisters of seed pods with germinated seeds immersed in a nutrient-rich gel.

4 Hover and plant. Flying at a height of 1 or 2 meters, the drones follow the planting patterns, firing the biodegradable seed pods down to the ground. The pods break open upon impact, allowing the germinated seed a chance to take root.

5 Monitor growth. After planting, the drones do low-level flights to assess the health of the sprouts and saplings.

Such “precision forestry,” as BioCarbon calls it, is extremely efficient. A farmer might hand plant as many as 3,000 seeds a day; Fletcher says his drones can drop up to 36,000 seed pods daily, often in areas where a human can’t reach. Working with local ecologists, BioCarbon will use the drones to spread a variety of tree species, as well as microorganisms and fungi designed to improve the soil quality. “The central focus is ecosystem restoration,” Fletcher says.

On a planetary climatological scale, Morton notes that “tropical deforestation plays a big role in global climate cycles,” claiming the accelerated pace of cutting and burning of forests accounted for 20 percent of greenhouse gas emissions in the 1990s. Fletcher and his team want to help reverse that trend. “By planting at the scale we’re looking at,” he says, “we can make a real longterm impact. We hope to do a lot of good in the world.”
