Forests in countries like Brazil and the Congo get a lot of attention from environmentalists, and it is easy to see why. South America and sub-Saharan Africa are experiencing deforestation on an enormous scale: every year almost 5 million hectares are lost. But forests are also changing in rich Western countries. They are growing larger, both in the sense that they occupy more and that the trees in them and bigger. What is going on?
Forests are spreading in almost all Western countries, with fastest growth in places that historically had rather few trees. In 1990 28% of Spain was forests; now the proportion is 37%. In both Greece and Italy, the growth was from 26% to 32% over the same period. Forests are gradually taking more and in America and Australia. Perhaps most astonishing is the trend in Ireland. Roughly 1% of that country was forested when it became independent in 1922. Forests cover 11% of the land, and the government wants to push the proportion to 18% by the 2040s.
Two things are fertilizing this growth. The first is the abandonment of farmland, especially in high, dry places where nothing grows terribly well. When farmers give up trying to earn a living from farming or herding trees simply move in. The second is government policy and subsidy. Throughout history, governments have protected and promoted forests for diverse reasons, ranging from the need for wooden warships to a desire to promote suburban house-building. Nowadays forests are increasingly welcome because they suck in carbon pollution from the air. The justification change; desire for more trees remains constant.
The greening of the West does not delight everyone. Farmers complain that land is being taken out of use by generously subsidized tree plantations. Parts of Spain and Portugal suffer from terrible forest fires. Others simply dislike the appearance of forests planted in neat rows. They will have to get used to the trees, however. The growth of Western forests seems almost as unstoppable as deforestation elsewhere.

The fifth largest city in US passed a significant soda tax proposal that will levy (征税)1.5 cents per liquid ounce on distributors.
Philadelphil's new measure was approved by a 13 to 4 city council vote. It sets a new bar for similar initiatives across the country. It is proof that taxes on sugary drinks can win substantial support outside super-liberal areas. Until now, the only city to successfully pass and implement a soda tax was Berkeley, California, in 2014.
The tax will apply to regular and diet sodas, as well as other drinks with adder sugar, such as Gatorade and iced teas. It's expected to raise $410 million over the next five years, most of which will go toward funding a universal pre-kindergarten program for the city.
While the city council vote was met with applause inside the council room, opponents to the measure, including soda lobbyists, made sharp criticisms and a promise to challenge the tax in court.
"The tax passed today unfairly singles out beverages — including low —and no-calorie choices," said Lauren Kane, spokeswoman for the American Beverage Association. "But most importantly, it is against the law. So we will side with the majority of the people of Philadelphia who oppose this tax and take legal action to stop it."
An industry-backed anti-tax campaign has spent at least $4 million on advertisements. The ads criticized the measure, characterizing it as a "grocery tax".
Public health groups applauded the approved tax as step toward fixing certain lasting health issues that plague Americans. "The move to recapture a small part of the profits from an industry that pushed a product that contributes to diabetes, obesity and heart disease in poorer communities in order to reinvest in those communities will sure be inspirational to many other places," said Jim Krieger, executive director of Healthy Food America. "indeed, we are already hearing from some of them. It's not 'just Berkeley' anymore."
Similar measures in California's Albany, Oakland, San Francisco and Colorado's Boulder are becoming hot-button issues. Health advocacy groups have hinted that even more might be coming.
