Comments Off on Scientists find air pollution leads to a significant decline in cognition

It turns out pollution affects more than just the environment. New research shows there might be a correlation between significant air pollution and cognitive decline in humans. Scientists hope their research will lead to changes in how countries deal with excessive air pollution, especially in heavily populated urban areas. Over the course of several years, more than 25,000 people hailing from 162 different counties in China were studied. The researchers published their findings in the Proceedings of the National Academy of Sciences and are calling for China to reform its pollution policies. The researchers believe China can significantly increase the population’s education level by adhering to the U.S. EPA guidelines. So, how did researchers link pollution with cognitive decline? The scientists performed verbal and math exams on all of the subjects in 2010 and again in 2014. The data from the exams were then compared between the years, and the team linked these changes to  air pollution . The researchers found that the older subjects performed worse on the tests, which led the team to believe that pollution has a bigger effect on brains as people age. The study also showed that individuals with little education were more affected by pollution, possibly because they typically work outdoors. Although the researchers were confident in linking pollution and cognitive decline, they are not sure why it is happening. Xi Chen, study co-author and professor of health policy at Yale, believes that pollution could be harming white matter in the brain , a region that controls communication within this important organ. James Hendrix, the head of the Alzheimer’s Association’s Global Science Initiative, disagrees. Hendrix does not believe the researchers have any evidence to suggest that pollution is damaging white matter. He also argues that associating air pollution with cognitive deterioration is difficult, because there are too many other factors at play. Either way, it’s clear that air pollution is negatively impacting our health and our planet. + Proceedings of the National Academy of Sciences Via NPR Images via Fredrik Rubensson and  Nicolò Lazzati

The Philippines envisions a green smart city to combat pollution in Manila

Comments Off on The Philippines envisions a green smart city to combat pollution in Manila

Traffic is an unpleasant facet of life in cities , but in Manila, the most densely populated city in the world , it’s a severe drain on the economy and the quality of life of residents. This metropolis in the Philippines is infamous for traffic congestion, which contributes to its substantial smog problem. With it also comes many other forms of pollution and environmental hazards. The country has an ambitious plan to combat these issues — build a new smart city that is green and resilient. The Plan The new city, dubbed New Clark City , is considered Manila’s twin city. It’s located in Central Luzon, about  75 miles from Manila at a former U.S. military base. It’s expected to be larger than the size of Manhattan and home to up to two million people . The Bases Conversion and Development Authority ( BCDA ), a government entity vested with corporate powers that converts former military properties, is the leading developer of the project. Both government and private investments will fund the new city. The government plans to move many of its offices and thousands of its workers to the smart city .  By the end of 2023, the government aims to have eight mid-rise government buildings and 8,000 housing units in New Clark City. The Department of Transportation has already moved to Clark , and BCDA will do so this year. One of the most notable parts of the project is the expansion of Clark Airport, which would double the volume of flights the facility can handle. This development is scheduled for completion in 2020. Related: Panasonic is building an incredible smart city outside of Denver Smart, Green and Resilient New Clark City aims to avoid many of the problems that plague Manila by emphasizing green design and smart technologies.  Two-thirds of the city’s land will be used for green space and agriculture . Developers plan to use green building techniques — such an energy monitoring systems and renewable energy — to increase energy efficiency and cut greenhouse gas emissions. The project is slated to include a  rail system connecting the new city to Manila . The inclusion of reliable public transport should alleviate some of the hassle for commuters, visitors and in-city residents alike. The Philippines anticipates autonomous cars will further reduce current and future congestion. While reducing traffic, these technologies are also expected to help keep air quality at the World Health Organization’s recommended safe levels — air pollution levels in Manila are currently  70 percent higher than WHO’s endorsed rates. New Clark City is designed with resilience to disasters in mind. The city’s elevation at its lowest point is 184 feet above sea level  to minimize the risk of flooding, and green space along rivers will also allow room for water to rise without damaging nearby property. In case of power disruption or an emergency, the city will also host backup government offices, so agencies can continue operations. The government said it is working to develop the city quickly while still keeping the design green. Challenges Against New Clark City The New Clark City project has received praise for its vision, and the plans suggest it could have substantial environmental and economic benefits for Manila and the Philippines. But such an ambitious project isn’t without its challenges. One of the primary roadblocks is getting residents to actually move to the city. To address this challenge, the Philippines is prioritizing connecting New Clark City to Manila via train to make the smart city easily accessible. The BCDA also hopes to attract people by building a sports facility that will host the 2019 Southeast Asian Games. Another critical strategy for jump-starting the economy and moving people to the urban center is to gradually relocate government agencies to New Clark City. Sustainable design is another critical challenge to this project. Because of the tight time frame, project managers had to carefully weigh the long-term needs of the natural world with the short-term profitability of the developers. To that end, they have spent time making sure the space, when finished, will prioritize natural landscapes and farmland. The Philippines expects to complete the full development plan within 30 years . In total, New Clark City is an approximately $14 billion project — a high price to pay, especially  if the city fails . A City for the Future The government hopes the benefits of New Clark City will outweigh the costs. As evidenced by the state of Manila’s traffic congestion and environmental problems, there is a demand for change. If New Clark City succeeds, its victory may enable Manila to revitalize and integrate more smart, green features, which could reduce the country’s environmental impact substantially. Building a new city from scratch — and keeping it green — is, of course, no small feat, but this modern city could mean a new, brighter future for the Philippines . + New Clark City Via  World Population Review ,  Rent PMI ,  Business Insider ,  Bloomberg ,  Reuters  and  CNN Images via New Clark City  and BCDA

Earth’s population just hit 7.5 billion people

Comments Off on Earth’s population just hit 7.5 billion people

Over 7.5 billion people now reside on planet Earth , according to the World Population Clock . But with more people could comes less access to resources like food and energy . A global population of 7.5 billion people has far-reaching repercussions – including increased greenhouse gas emissions , strained food supplies, and increased total consumption, according to Charity organization Population Matters . Population Matters says that population growth could keep some countries in poverty , and it intrudes on land needed by wildlife . Head of Campaigns Alistair Currie told edie.net , “We will see cutthroat competition for shrinking resources which will include not just fossil fuels but productive land and water, pushing prices up not just for consumers but for the businesses and industries which need them too. Huge potential markets like much of sub-Saharan Africa will be stuck in poverty and we’ll see political instability arising from population and migration pressures, including conflict over resources.” China has the most people in one country; 1.38 billion people live there. India is next with 1.34 billion, followed by the United States with 326 million. The United Nations thinks our global population will hit 10 billion people by the year 2056. Related: Scientists say the world is “one crop breeding cycle away from starvation” Currie warned that while businesses may see increased global population as the opportunity to gain more customers, too much growth won’t be good for our planet – or business. He said, “Growth cannot continue indefinitely on a finite planet and fewer consumers is ultimately better for all of us. Business must start recognizing and adapting to that reality. With action now, we can limit population growth and eventually reach sustainable levels.” We’re currently using up the resources of 1.6 Earths , and we’ll need 3 Earths by 2050 unless we can alter our consumption patterns. + Population Matters Via edie Images via Stròlic Furlàn – Davide Gabino on Flickr and McKay Savage on Flickr

Have we reached peak food? Authors of a new study in Ecology and Society say “yes,” claiming our ability to grow more food has reached its limit, despite advances in growing technology, even as the population increases. But others say that if we simply stop wasting food , we won’t have a problem.

Should Human Remains be Composted as a Soil-Building Project?

Comments Off on Should Human Remains be Composted as a Soil-Building Project?

Everything that lives will eventually die: it’s the one absolute that can be counted on. One question that comes to everyone’s mind eventually is what to do with their body after they’ve passed away; some choose cremation while others choose standard burial , but as the population grows and urban areas sprawl, will there be enough space to inter everybody once the time comes? Or should we be looking at a more eco-friendly, forward-thinking solution? Enter The Urban Death Project : a system designed by Katrina Spade for the disposal of our dead in cities. The project utilizes the science of composting to safely and sustainably turn bodies into soil-building material, which is then used by nearby farms and community gardens. Envisioned as a place to honor the dead at a neighborhood scale, the project supports sustainable cities by engaging inhabitants in issues of soil heath, resource depletion, and climate change. Our bodies, once no longer needed , can gracefully and respectfully be broken down back into the basic materials they’re made from, and then used as mineral-rich compost to nourish soil and nurture plant life.
