Almost 20,000 pieces of space debris are currently orbiting the Earth. This visualisation, created by Dr Stuart Grey, lecturer at University College London and part of the Space Geodesy and Navigation Laboratory, shows how the amount of space debris increased from 1957 to 2015, using data on the precise location of each piece of junk.
Celebrants ringing in the new year left behind tons of confetti and garbage. Last year, crews with the city's Department of Sanitation collected more than 48 tons of debris in wake of the iconic party.
Amounts of waste are largely determined by two factors: first, the population in any given area, and second, its consumption patterns – which are controlled by the evolution of Gross Domestic Product per Capita (GDP/c).
According to the UN, between now and 2025, the world population will increase by 20% to reach 8 billion inhabitants (from 6.5 today). Moreover, by 2050, the total population will be around 9.5 billion, unless specific control measures are broadly adopted. If this becomes a reality then a population of 8-8.5 billion in 2050 may be considered a successful stabilization of numbers.
It is important to note that 97% of this growth will happen in Asia and Africa, which includes some of the poorest countries that have the least capability to absorb it. After 2025 it is expected that Asia will hold more than two thirds of the world’s population. This growth also will boost urbanization of the population (urban population is expected to be around 65% of the total one after 2040), and the creation of extended zones of poverty around and inside megacities. The number of inhabitants of slums will be double around 2025 and will reach 1.5 billion.
Besides overpopulation, a remarkable increase in GDP/c especially in developing countries is on its way. In 2025, world production will have doubled in relation to 2005. By 2050 the world production may again have doubled compared to 2025. The global average GDP/c around 2025 will be more or less one and a half times the current one, and in a business-as-usual scenario it may be fourfold around 2050. Jeffrey Sachs has estimated that in developing countries the GDP/c will be around $40,000 in 2050, which is the same as the USA GDP/c in 2005! It also seems that we are living in a richer world where we will have higher actual numbers of poor people, but less in terms of percentages.
As GDP/c goes up, it is expected that by 2050 the demand for agricultural goods will rise by 70% and the demand for meat will double.
It has been estimated that urban food waste is going to increase by 44% globally between 2005 and 2025. During the same period, and because of its expected economic development, Asia is predicted to experience the largest increase in food waste production, from 278 million to 416 million tons.
If present waste management trends are maintained, landfilled food waste is predicted to increase world CH4 emissions from 34 million to 48 million tons (31 million to 43 million tonnes) and the landfill share of global anthropogenic emissions from 8% to 10%.
From 2000 to 2008, the European exports of plastic waste rose by 250%, reaching 2.27 million tones – approximately 5 million tones are annually recycled in Europe. Around 87% of these exports are going to China, including Hong Kong. The global financial crisis seems to have worsened the situation, as the first quarter of 2009 saw a 33% increase in exports compared to the previous year.
Between 1995 and 2007, the amount of non-hazardous waste exported to Asia increased tenfold for waste paper, elevenfold for plastics and fivefold for metals. At the same time, just for a comparison, the amount of paper and cardboard packaging waste recycled has increased from about 24 to 30 million tons and the amount of plastic packaging recycled has increased from about 10 to 14 million tons.
...more than 20 million containers of waste are now shipped each year, either legally or illegally, from the EU to non-EU countries.
Millions of tonnes of plastic waste are floating around Pacific Ocean. It is estimated that more than 80% of this waste is coming from land-based resources and the rest from marine-based resources.
Our world will be overpopulated and more and more interconnected. The defining challenge of the 21st Century will be that humanity shares a common fate. That fate is already demanding new forms of global cooperation. The paradox of a unified global economy and divided national societies poses the single greatest threat for our planet. And although there are appropriate waste management solutions, the main problem is the global framework that should put them in place where they are most needed. Let’s try to create it.
We are messing up, banning chemicals that we prove bad but not looking at the overall picture. The tipping point is coming soon on this, the climate change is already past the tipping point. So now we need to go way overboard to reverse climate change. The same will happen when our Ecosystem starts to collapse.

The irony of everything wrapped in plastic was that it was the enviro lobby who wanted us all to switch to plastic because it was to save the trees!
Somehow, I wonder if we're all going to feel the same way about CFL lightbulbs in a few years when the mercury poisoning starts to really be an issue.

The environmentalist movement is a front for an exclusive club of shady, wealthy billionaires who get funding from foreign entities, Senate Republicans charged Wednesday in a 92-page report.
The report details the activities of the “Billionaire’s Club,” which it said meets regularly to coordinate donations and control of far-left environmental groups that want to restrict the use of fossil fuels. The donors use “legally suspect” means of controlling the groups that is unique to the left, the report said.
Furthermore, the Obama administration has enabled these groups by hiring former employees and funnelling government money to the organizations.

I think that we are going to be killed off using chemistry added to our diets. All they will need is one added chemistry and most of us will die. or if they remove one food chemistry we will be their servants. Look at this article, it is about ants but wonder how they can retrofit this new knowledge.

It's only a matter of time now.
Almost half of tested samples of commercial high-fructose corn syrup (HFCS) contained mercury, which was also found in nearly a third of 55 popular brand-name food and beverage products where HFCS is the first- or second-highest labeled ingredient, according to two new U.S. studies.
HFCS has replaced sugar as the sweetener in many beverages and foods such as breads, cereals, breakfast bars, lunch meats, yogurts, soups and condiments. On average, Americans consume about 12 teaspoons per day of HFCS, but teens and other high consumers can take in 80 percent more HFCS than average.
"This study appears to be based on outdated information of dubious significance," said Audrae Erickson, president of the Corn Refiners Association, in a statement. "Our industry has used mercury-free versions of the two re-agents mentioned in the study, hydrochloric acid and caustic soda, for several years.
"Our studies indicate that switching the sign of a synapse not only provides a novel synthetic mechanism to flip behavioral output but could even be an evolutionary mechanism to change behavior," said Alkema. "As we start to unravel the complexity and design of the neural network, it holds great promise as a novel mechanism to test circuit function or even design new neural circuits in vivo."
