Where did the stars go?

One day, you find time to get out of the clutches of your work life and you decide to gaze at the stars. 

Something which you used to do when you were a kid. 

But the city life with all its glory has diverted you to other ‘fun’ things.

But to your amazement you find that the density of stars has drastically decreased.

'That’s preposterous’- you say to yourself. That can’t be true.

You are positive that it has something to do with you aging.

You decide to go to your eye doctor and do a thorough check up. The doctor concludes that your eye sight is perfect.

You are delighted,  knowing that your eye sight is perfect and that you are going to see those stars again. You spend all day lamenting about it. 

You crave for the starry night sky. And you are sure it would look like so :

So, the following night you go to the terrace to rejoice at the sight. But yet see that the sky is not starry at all as you had marveled. 

In fact, there is a stark difference between what you had in mind and what you observe.

You get increasingly concerned about it. You ask a few people around and you find out that the answer to this mysterious phenomenon is Light Pollution..

And you start to explore this new bizarre form of pollution.

What is Light Pollution?

Alteration of natural light levels in the outdoor environment owing to artificial light sources.

What does it do?

The impact of light pollution is to reduce our eye’s limiting magnitude. That means that we can see fewer and fewer stars.

The differences in the number of stars that can be seen due to varying levels of background light pollution.

Light pollution competes with starlight in the night sky for urban residents, interferes with astronomical observatories, and, like any other form of pollution, disrupts ecosystems and has adverse health effects.

Light pollution is a side effect of industrial civilization. Its sources include building exterior and interior lighting, advertising, commercial properties, offices, factories, streetlights, and illuminated sporting venues. 

How can I prevent it?

(Light Pollution and How to Reduce It)

The solution does not involve curtailing nightlife, hampering the nighttime economy or compromising safety. It just requires directing lights where they’re needed and eliminating waste.

Here what you can do prevent light pollution.

1) Only turn on outdoor lights when needed—or install motion sensors.

2) Point the lights downward and outfit them with “shields” to prevent light from traveling sideways. The goal is to shine them only where illumination is wanted—not in people’s eyes or on other people’s property (a case of “light trespass”).

3) Lower the wattage of your bulbs and put them on dimmers. Bright lights and dark shadows don’t improve safety, but reduce it.

4) Close curtains at night to keep indoor light in. If you live in a multi-story building, use black-out curtains to prevent bird crashes.

And, of course, please use energy-efficient lights to cut global warming emissions even more than you’ll be doing already.

Here’s what the night sky looks now, with light pollution.

And here’s how it will look like without it.

This post is to educate all the followers of the blog about Light Pollution, and raise awareness about it.

“Stars can’t shine without Darkness”

and hence i urge you to do your part to curbing Light Pollution.

Have a good day :)

Microbeads banned! A victory against ocean plastic pollution

Good news, land and sea dwellers! Congress and the White House just cooperated—with remarkable bipartisan speed—to eliminate an insidious source of plastic pollution in the ocean. 

Microbeads are tiny plastic balls often used as exfoliants in everything from soap and facial scrub to toothpaste. When we rinse them off, they wash down the drain and flow into the ocean, lakes and rivers, where they can absorb other pollutants such as DDT and PCBs. Fish and other marine animals often mistake microbeads for food, concentrating these toxins up the food chain—potentially ending up in seafood on our plates.

The Monterey Bay Aquarium and other leading public aquariums nationwide supported the passage of statewide microbeads bans in California and in other states. At the federal level, we worked to strengthen the language of the Microbead-Free Waters Act, urged Congress to pass the bill and asked President Obama to sign it into law.

Chinese buy up bottles of fresh air from Canada
Canadian company which started out as a joke bottling Rocky Mountains air has seen its product fly off the shelves in pollution-hit China, with first shipment selling out in four days

A Canadian start-up company bottling fresh air from the Rocky Mountains has seen sales to China soar because of rising pollution levels.

Vitality Air was founded last year in the western Canadian city of Edmonton but began selling in China less than two months ago.

“Our first shipment of 500 bottles of fresh air were sold in four days,” co-founder Moses Lam says in a telephone interview with the Telegraph.

A crate containing 4,000 more bottles is making its way to China, but he says most of that shipment has been bought.

A 7.7 Litre can of crisp air taken from Banff National Park in the majestic Rocky Mountains range sells for roughly 100 yuan (£10), which is 50 times more expensive than a bottle of mineral water in China.

Pollution in China has gotten so bad, people are buying fresh air in a can

With air pollution in China reaching unprecedented levels, one company has found a novel solution: bottled air. The whole idea began when Moses Lam sold a Ziploc bag of Canadian mountain air on eBay for 99 cents. He tried it again and sold a second bag for $168. It was a success. But that was nothing compared to the business he’s been doing in China.

By 2050, there will be more plastic garbage in the ocean than fish.
A new study from the World Economic Forum and the Ellen MacArthur Foundation estimates that at some point within the next 34 years, the quantity of plastic waste floating in the world’s ocean will outweigh all the fish in the sea put together. It’s only going to get worse without serious efforts to change on our part.

Human impact has pushed Earth into the Anthropocene, scientists say
New study provides one of the strongest cases yet that the planet has entered a new geological epoch
By Adam Vaughan

Humans have had such an impact on natural processes that it has brought the globe into a new geologic era, according to a new assessment from a group of geoscientists. The Anthropocene, as they’re calling it, would end the Holocene period, which began almost 12,000 years ago. The impact that humans have had on the world’s atmosphere, oceans, and ecosystems are “as big as those that happened at the end of the last ice age,” according to one author of the study. The “new era” will be presented to the international commission that formally approves such time divisions later this year.
