Plastic Found in Bottled Water

A new test, conducted by scientists from the State University of New York, shows that bottled water has microplastic particles in them.

250 bottles of water from nine different countries were examined. More than 90% contained tiny pieces of plastic. Sometimes concentrations were as high as thousands of plastic pieces per litre of water. Only 17  examined bottles were free of plastic.  On average, 10 plastic particles, about the width of a human hair, were found in each litre of water.

The companies, whose bottled water was examined, claim that their production met the highest quality standards. In most cases, the plastic gets into the water through the packaging process.

Although the results are not catastrophic scientists and doctors are concerned.  However, they state that there is no proof that the smallest particles of plastic can cause damage to your body. Most of it is turned into waste which leaves the body through faeces.

Apart from bottled water, plastic particles have also been found in beer, tap water, seafood and even in the air.

Bottled water is the fastest growing beverage in the world.  Currently, about 150 billion dollars worth of  water is sold worldwide. Packaged water is especially important for millions of people around the world who do not have access to safe drinking water.

Polar Bears Could Face Extinction Earlier Than Thought

Polar bears could become extinct faster than predicted. That is because there is a shortage of food in their habitat and scientists have now found out that polar bears need more energy than previously thought.

As a result of global warming, Arctic ice is melting quickly, so that polar bears have to travel further in search of food. In a study that has spanned the last three years, scientists found out that polar bears have to travel one and a half times more than in the past.  As a result, they lose weight.

Experiments conducted with modern technology show how polar bears move and behave. High-tech GPS collars were put on 9 female polar bears. Their movements and energy consumption have been tracked over a period of 12 days. Results show that a few of them lost up to 10%of their weight.

According to the World Wildlife Fund, polar bears spend half of their time hunting for something to eat. They rely mostly on young seals as the main source of food, but the seal population is getting scarce because of the melting ice.

A polar bear needs about 12000 kilocalories a day to stay healthy and even more to put on the body fat it needs to survive the winter months.

Over the past ten years, the number of polar bears has declined by 40%. Ice on their habitat, Arctic Sea ice is decreasing at a rate of 14% per decade.  It is currently at its lowest level in 40 years.

Coca-Cola Wants To Recycle All Packaging By 2030

Coca-Cola, the world’s largest soft drink corporation, is planning to recycle all of its bottles and cans by 2030. The company wants to take on more responsibility and make its contribution to saving our environment. The company sells over 500 types of fizzy drinks, juices and mineral water around the world.

Coca-Cola has announced a campaign called “World Without Waste“. It says that food and beverage companies are responsible for much of the litter that can be found on streets and beaches.

The company said it wants to increase the amount of material that can be recycled in its products. By 2030 Coca-Cola aims at making 50% of all the content in bottles and cans recyclable. It also intends to advise users on how to recycle products best. Coca-Cola plans to work together with local governments and environmental groups.

On the other side, Coca-Cola has also stated that that packaging is important because it can reduce the amount of spoilt food and can extend the shelf life of food products.

Greenpeace, one of the most important environmental organisations,  has welcomed the move but also said that the company should focus especially on reducing the amount of plastic that is produced. Plastic bottles are a major problem because plastic does not break down and degrade quickly. It is eaten by animals and fish and ends up in our food chain.

EU Plans To Recycle All Plastic Waste by 2030

The European Union has released plans to recycle all plastic by the year 2030. It wants to ban all types of plastic that can only be used once. The measure comes as a  consequence of China’s decision to ban imports of foreign plastic that is to be recycled in in the country. Currently, the EU exports half of its collected plastic,  most of which goes to China.

The European Commission also plans to reduce plastic waste that is washed up on North Sea, Atlantic and Mediterranean shores. According to the new proposal, it will be illegal to dump plastic waste in the open seas.

Although the EU does not want to introduce a tax on plastic yet, it does aim at the development and production of new kinds of plastic that can be recycled in Europe. EU countries produce 25  million tons of plastic every year but only a fourth is recycled. It takes plastic hundreds of years to degrade.

The EU wants to invest 300 million euros to develop better plastic materials. The new strategy aims at making plastic recycling more profitable

While the production of one-time-only usable plastic items, like drinking straws, coffee cups and takeaway packaging is to be reduced, families should also be persuaded to cut down on plastic usage altogether.

Non-EU countries are also considering cracking down on plastic. Some countries have already started to tax the use of plastic bags. Iceland has announced that it will ban all plastic packaging for domestic products.

Ozone Layer Over Antarctica Is Slowly Recovering

According to the American space agency  NASA, the world’s ozone layer is slowly recovering. A report states that, for the first time,  scientists have observed a decrease in the amount of chlorine in the ozone layer over Antarctica.

Ozone in the atmosphere is essential because it protects life on our planet by absorbing dangerous ultraviolet radiation, which causes skin cancer and damages plant life. Is the 1980s, scientists discovered a hole in the ozone layer, which has become larger ever since.  It is especially large over the Antarctic continent and Australia.

Shortly after the discovery, an international agreement, the Montreal Protocol, was signed, banning the use of substances that are responsible for the destruction of the ozone layer. It limits the use of CFCs, chemical compounds that rise into the upper layers of the atmosphere where they are broken down by the sun’s ultraviolet light. In the process, chlorine is released which destroys the ozone molecules.

Since the ban has taken effect major companies have started looking for alternatives to CFCs.

Changes in the ozone level are usually measured during the Antarctic winter, between July and September, when temperatures are lower and results are more accurate. Since 2005, there has been a 20% rise in the amount of ozone. Even though it is the first time that the hole in the ozone layer has become smaller it will take decades to recover completely.

Environmentalists around the world have welcomed the announcement, stating that we can actually save the environment by acting decisively.

Bleaching Endangers World’s Coral Reefs

A recent study shows that the world’s coral reefs have been showing signs of strong bleaching due to global warmingIn the 1980s bleaching was rare, occurring about once every 25 years. Now the rate has risen to about once every five years. Environmentalists predict that by 2050 bleaching will happen every year or two.

Bleaching is caused when warm water breaks down the algae inside the reefs. They provide food for the corals and keep them healthy. When algae fall off, corals lose their colour and can die within a short period of time. Even if the water surrounding the reefs gets colder again it may take years for the damaged reefs to recover completely.

While bleaching is especially a problem in the waters of the Carribean Sea and Western Atlantic, reefs around Australia and South Africa have hardly been hit. In addition to the warming temperatures of the oceans, coral reefs are also endangered by pollution and overfishing.

Coral reefs are an important ecosystem. They are home to 25% of all marine species and provide a  habitat for countless types of fish. Reefs protect coastal regions from flooding and tidal waves. In addition, coral reefs are tourist attractions that lure millions of people every year.  The tourist industry around the Great Barrier Reef in Australia, for example, is worth about 5 billion dollars a year.

Chocolate in Danger of Becoming Extinct

Chocolate may be in danger of becoming extinct by the middle of this centuryPests and fungal diseases have been found in cacao trees that may endanger the crop’s survival.

In addition, cacao is also under attack by global warming. Trees grow in a very small area about 20° north and south of the equator, where humidity and temperatures are the same all year round. By 2050 rising temperatures and drier weather will push cacao production up into mountainous areas, many of which are home to wild animals.

Scientists from the University of California are trying to save the plant. Together with researchers from the American food company Mars, they are trying to grow cacao seeds that are more resistant and can grow at higher altitudes.

Most of the world’s cacao production comes from two countries in western Africa, Cote d’Ivoire and Ghana. These areas may not be suitable for cacao production in the decades to come. Millions of farmers depend on cacao for a living.

Artificial Light Makes Our World Brighter

A new study of satellite images has revealed that our planet is getting brighter and brighter during the night. More and more artificial lighting may cause harm not only to humans and animals but whole ecosystems.

The study has found out that the quantity of light has increased by 2.2 % per year over the last decade. Much of that increase comes from the Middle East and Asia, while in Europe and the USA brightness has stayed about the same.  Only a few countries have actually seen a decrease in the amount of light. Among those are Syria and Yemen.

Artificial light on earth is growing because more and more towns and other settlements are being created in places that were once farmland, forests or wilderness. In addition, China and other booming economies are building whole cities in sparsely populated areas.

Even though large areas of land surface remain dark, there are places on earth where lights never go out, for example, shopping malls, dining districts or international airports.

The technology of artificial lighting is also changing. More and more LED lights are replacing older light bulbs. They are more energy-efficient and emit a brighter bluish-white light. As they are becoming cheaper people tend to buy more.

Doctors warn that too much artificial light can bear health risks. It can lead to shorter periods of sleep, insomnia and changes in a person’s biorhythm.

Scientists have claimed that increased light have an effect on animal habitats. More light near beaches may affect the turtle population that comes there to lay their eggs. Migrating birds that rely on stars to navigate can be influenced by light and travel off course.

NASA Software Shows How Sea Level Rises Affect Cities

NASA scientists have created a new software program that can show how cities in coastal regions are endangered by flooding and sea level rise caused by global warming. The simulation shows how 300 coastal cities will be affected in the next century.

The software was developed by  NASA’s Jet Propulsion Laboratory. It calculates which ice sheets and glaciers are melting and how the additional water influences coastal regions. It takes into consideration the rotation of the Earth as well as the influence of gravity. The results are surprising. Sea levels will actually decrease around cities closer to ice masses, while the biggest rises will occur through ice caps that are farther away.

New York, for example,  will be most affected by melting ice caps in northeastern  Greenland. Sydney, on the other hand,  will actually be influenced by parts of Antarctica that are far away from Australia’s city.

The software aims at helping city planners prepare for sea level changes within the next few decades and how to keep ocean water out.

A climate report published this week shows that, since 1900, global sea levels have risen by about 20 cm, with half of the rise occurring in the last 25 years. Projections show that by 2100 ocean levels will rise by an average of 1 metre, however, the rise will not affect all coastal areas in the same way.

Smog Returns to Delhi

Deadly smog has returned to Delhi. Air pollution reached several times the level suggested by the World Health Organisation. People were told to stay indoors and not walk on the streets of the world’s most polluted city. Doctors declared a state of emergency and some schools in the city stayed closed.

Smog in northern India is a big problem, especially during the winter months. From November to March cold temperatures force pollutants and dirt particles closer to the ground, mixing with the foggy air. Low wind speeds and dust from construction sites have also contributed to high pollution levels in the area.

Environmentalists say that factories and traffic are the biggest causes of smog. In addition, farmers in northern India burn the leftovers of crops after harvest and therefore produce more smoke.

Critics say that Indian government is not doing enough to protect India’s second-largest city. New measures took effect last October. Traffic became more regulated and several power plants were shut down. Authorities also want to restrict the personal use of cars to every second day, a measure that already worked in the past.

Last November Delhi was hit by the highest air pollution levels in 20 years, forcing over a million children to stay at home. Researchers claim that 2.5 million Indians die of pollution every year.
