Hunger for Concrete Destroys Mountains in Cyprus

From Cyprus to New Zealand, Lebanon and beyond, environmentalists worry about the proliferation of quarries in a world ever greedier for concrete. Concrete consumption has tripled over the past 20 year.

Over 40 billion tons a year of sand and gravel are extracted around the world from mountains, rivers, coastlines and marine environments, the majority for construction. With the global population expected to grow by two billion by 2050, demand can only go up, according to the UN environment agency. The extraction process often comes with deforestation, air pollution and disruption of traditional human activities.

This is the case in Cyprus, near the hut where Jamal makes traditional "hellim" cheese, trucks come to collect rock, kicking up clouds of dust and frightening the animals.

On the quarried area of the mountain slope, vegetation has disappeared. A policeman asks the goat herder to stay back as an explosion triggers a huge cloud of smoke and part of the rock face collapses. On another mountain, Jamal was injured and lost animals to quarrying work.

Rocks "rained down on us," he recalled.

While he understands the "need for rock to build", he hopes the company running the site will help him find quieter pastures in the Turkish Republic of Northern Cyprus established in 1974, and on which live 355,000 people. This region walks the line between development and conservation.

Cenk Sarper, head of the Stone Quarries Union, said: "Today, the island is fed by tourism so we need hotels, guest houses, roads and airports. We don't have any other choice than to exploit the quarries."

He said the quarries operate in areas far from residential zones and respect all the adopted environmental standards. More than 12,000 tons of rock is extracted every day, or around 33 kilograms per capita. The world average is 18 kilograms, according to the UN.

Asking to remain anonymous, a contractor said that key actors "did not do everything possible to limit visual pollution." Some accuse companies from Turkey of being less vigilant than Turkish Cypriot ones.

The secretary general of the biologists' association in northern Cyprus, Hasan Sarpten, regrets that a large quarry was authorized far from a reserved area, in the west.

"They are not applying the best methods" environmentally, he said, criticizing the lack of regulation by Turkish Cypriot authorities.

These authorities declined to comment when contacted by AFP.

Environmentalists are equally worried in the internationally recognized Republic of Cyprus.

Environment expert Klitos Papastylianou said: "The growing extraction of raw materials for the construction industry is one of the main threats for protected areas."

Green Party MP Charalampos Theopemptou noted that "marinas and coast protection works require huge amounts of rocks."

An audit recommended increasing fines to discourage illegal quarrying. Calls for stricter controls resound around the world. In Lebanon, where illegal quarries have cleared entire mountains and hundreds of thousands of trees, activists are pushing back, despite death threats.



Should You Stretch before Exercise? After? Never? Here’s What to Know

Should You Stretch before Exercise? After? Never? Here’s What to Know

For many people of a certain age, high school gym class began with reaching for their toes. Then, over the years, we were told it was better to stretch after exercise.

It turns out, both those things can be true, but the differing advice has created some confusion.

Stretching can help make you more flexible, improve range of motion in your joints — and feel good. David Behm, who researches human kinetics at Memorial University of Newfoundland in St. John’s, Canada, offers this advice on when to stretch and how to do it safely:

Warm up first

It’s almost always good to stretch, but it’s better if you warm up first, said Behm, author of "The Science and Physiology of Flexibility and Stretching." He recommends a light aerobic activity such as jogging, walking or cycling for five or 10 minutes.

Follow that with some static stretching, the traditional way of reaching and holding a position (think back to that gym class). You can then do activity-specific dynamic stretching, in which you warm up the muscles with repetitive movements like leg lifts.

Behm says one minute is "the magic number" for how long to do static stretching per muscle group without fatigue.

Expand your definition of 'stretching'

Should you always stretch before exercising? If it's traditional stretching, not necessarily.

The better question, Behm says, is, "Should people increase their range of motion? Should people have better flexibility? And that is yes, because it helps prevent injuries. It helps with health. But you don’t have to stretch to achieve that."

Resistance training, for instance, can be an effective form of stretching, he said. Doing a chest press increases range of motion in your deltoids and pecs, whether with barbells, dumbbells or machines, so there is no need to stretch beforehand. Just make sure to start with a small amount of weight to warm up and then add more to train.

"You probably don’t have to do extra stretching unless you’re a gymnast, a figure skater, or even a golfer who needs a great range of motion through that swing," Behm said.

Nor do you need to stretch first if you’re going for a leisurely run. Simply start with a slow jog to warm up and then increase the pace.

Don't do it if it hurts

After exercise, "light stretching is OK, as long as you don't reach a point where you're feeling pain," Behm said. Since your muscles will be warm by that point, overdoing it makes you more likely to injure yourself.

Foam rollers can help with muscle recovery and have been shown to increase range of motion as well as stretching.

Do some static stretching before sports

If you’re playing a sport, Behm said, static stretching beforehand helps reduce muscle and tendon injury.

"If you’re going to do an explosive movement, change of direction, agility, sprint, any of these explosive activities that involve your muscles and tendons," he said, "you’re going to be stronger if you do static stretching."

People can especially get in trouble when they go back to a sport they used to play, whether it's tennis, surfing or any sort of team activity.

Also, stretch both sides equally. Lacking flexibility on one side also can lead to injury.

Sounds simple. Why all the confusion? Different studies over the years have either encouraged or discouraged stretching before exercise. Behm says that partly because some studies didn't reflect real-life conditions, or were designed with elite athletes in mind, not regular people.

"If you’re Usain Bolt, it makes a difference," said Behm. Not so much for the rest of us.
