Insects On The Menu | Earth Wise

By Leave a Comment

According to the World Food Programme, a record 349 million people across 79 countries are facing acute food insecurity.  This constitutes a staggering rise of 200 million people compared to pre-pandemic levels.  Nearly one million people globally are fighting to survive in famine-like conditions, which is ten times more people than just five years ago.  

As a result, many experts contend that alternative or so-called novel food sources – such as lab-grown meats, seaweed aquaculture, and insects – will be necessary to help fight global hunger and global food insecurity. 

Insects already form a significant part of diets in many cultures around the world.  Insects are great sources of nutrients, including protein, vitamins, and minerals.  But insects have yet to be embraced in any substantial way in western cultures… but that may be changing. 

In fact, the European Union has now certified four types of bugs as food fit for human consumption.  The larvae of lesser mealworms and house crickets recently became the third and fourth insects approved for sale as food in the EU, joining yellow mealworms and grasshoppers. Eight more applications are awaiting approval.

Insects are already a delicacy in many high-end restaurants around the world, and a normal and healthy part of diets in countries like Mexico and Thailand.  Embracing insects as a food of the future will not only help in the fight against global hunger, but will also help to reduce greenhouse gas emissions and to slow species extinction. 

In Western food markets, the so-called “yuck factor” remains the biggest hurdle to cross.  But as the world population grows, the need for sustainable solutions in the food industry grows with it.

Coronavirus Shutdowns And The Environment | Earth Wise

By Leave a Comment

Our stories often discuss how human activities change the natural environment.  With most of us confined to our homes, the lack of human activities is having profound effects on the environment.  We are talking about some of these this week.

The COVID-19 pandemic is a global catastrophe, but it has ironically been a boon for the environment.  By taking billions of people off the streets around the globe and slashing all forms of travel, the global environment has seen dramatic changes.

Sea turtles in many countries are prospering by not having to compete with humans for precious beach space.  Animals everywhere have more freedom to roam and are taking advantage of the opportunity. The Himalayas are visible from parts of India for the first time in decades.

Satellite imagery has shown dramatic drops in nitrogen dioxide emissions in China, where pollution from vehicles is a serious public health problem.  Similar reductions in air pollution are evident in India, Italy and even in Los Angeles.  The city that is notorious for its smog suddenly has pristine air.

In Venice, water in the canals has become clear in the absence of heavy boat traffic stirring up sediments from the bottom.  Wildlife that normally is invisible such as jellyfish are being spotted.

Not all the changes to animal behavior are desirable.  Some wildlife that have become dependent on humans as a source of food are becoming aggressive and are taking to the streets of cities to look for food.  Monkeys in Thailand are mobbing towns and brawling, hunting for things to eat.  Rats in New York City are fighting over suddenly meager food supplies.

In many ways, the natural world is reacting to much of humanity sheltering in place.

Rising Seas Will Erase Cities

By Leave a Comment

According to new research, climate-driven sea level rise could affect three times more people by 2050 than previously thought.  This sobering assessment means some of the world’s great coastal cities, including Bangkok, Shanghai, Mumbai, Basra, Alexandria, and Ho Chi Minh City, could be in big trouble.   

Scientists have always relied on land elevation data to determine the effects of sea level rise over large areas.  But standard elevation measurements using satellites struggle to differentiate the true ground level from the tops of trees or buildings.  The authors of the paper developed a more accurate way to calculate land elevation by using artificial intelligence to determine the error rate and to correct for it.  The new findings revealed that 150 million people – three times more than previously thought – are now living on land that is projected to be below the high-tide line by the middle of this century. 

Eight Asian nations – China, Bangladesh, India, Vietnam, Indonesia, Thailand, the Philippines, and Japan – account for about 70% of the people living on at-risk land. 

More than 20 million people in Vietnam, including much of Ho Chi Minh City, live on land that will be inundated by 2050.  In Thailand, more than 10% of its citizens, including much of Bangkok, currently live on land imperiled by projected sea level rise. 

This new research was produced by Climate Central, a New Jersey-based science organization, and was recently published in the journal Nature Communications. 

Sea level rise is clearly not just an environmental problem.  It’s a humanitarian crisis.

Lots Of Renewable Energy Jobs

By Leave a Comment

According to the International Renewable Energy Agency, there were 11 million people employed in renewable energy worldwide in 2018.  This compares with 10.3 million in 2017.  So roughly three-quarters of a million new jobs were added last year.   As more and more countries manufacture, trade and install renewable energy technologies, renewables jobs continue to reach new high levels.

The geographic footprint of renewable energy jobs is changing.  Until now, renewable energy industries have remained relatively concentrated in a handful of major markets such as China, the US, and the European Union.  But more recently, East and Southeast Asian countries have emerged alongside China as key exporters of solar technology.  Malaysia, Thailand, and Vietnam were responsible for a greater share of growth in renewables last year.  Overall, Asia has a 60% share of renewable energy jobs worldwide.

Beyond climate goals, low-carbon economic growth has become a driver for renewables technology.  Renewables deliver on all the major elements of sustainable development:  environmental, economic and social.

The solar photovoltaic industry continues to be the most dynamic renewable enterprise.  It accounts for a third of the renewable energy workforce with more than three million jobs.  

Biofuel jobs were up by 6% to over 2 million.  Wind power supports 1.2 million jobs, with onshore projects predominant.  But the offshore wind segment is gaining traction.  Hydropower is still the largest installed capacity of all renewables but is now only expanding slowly.  The hydropower sector employs 2.1 million people directly, three-quarters in operations and maintenance.

Packing With Banana Leaves

By Leave a Comment

More and more places are instituting bans on single-use plastic bags.  Places like California and Hawaii already have bans in place and New Jersey is considering such a ban.  New York’s law will go into effect next March.  Supermarkets will no longer provide plastic bags at the checkout line.  But the laws have some exceptions, including the plastic bags used to hold produce and to pack up meats.

Banning or reducing single-use plastic bags is a growing trend in Asia as well including places like South Korea, Vietnam and Thailand.

One supermarket in Thailand came up with a novel approach to eco-friendly packaging:  wrapping produce in banana leaves.  The idea quickly became a viral hit on social media and drew the attention of supermarkets in Vietnam.  Several big supermarket chains in that country also began experimenting with banana leaves as a packaging alternative.

Representatives of Vietnam’s Lotte Mart chain said that the banana leaf packaging was still in the testing phase, but they plan to replace plastic with leaves nationwide very soon.  Aside from wrapping vegetables and fruits, the grocery chain intends to also use the leaves for fresh meat products.

Customers seem to be quite positive about the new packaging noting that it is actually quite attractive visually.  The banana leaf packaging also makes people more aware of the need for protecting the environment.

While Vietnam is a relatively small country, it turns out that it ranks number four in the world for the largest amount of plastic waste dumped into the ocean.  The country disposes of about 2,500 tons of plastic waste per day. So, efforts like the banana leaf packaging are not just symbolically important, they are genuinely a major environmental imperative.

Reducing Slavery In Seafood

By Leave a Comment

The seafood industry is one of the largest employers in the world.  But according to a 2016 report, the seafood industry also contains widespread forced labor.   Forty seven seafood-producing countries were reported to utilize forced labor.  The seafood hub countries of Indonesia, Thailand, Vietnam, Peru, and the Philippines were also reported to use a significant percentage of child labor.

A Plastics Promise

By

It’s estimated that five to thirteen million tons of plastic enters our oceans annually, where much of it can linger for hundreds of years.  According to a report by the World Economic Forum and the Ellen MacArthur Foundation, scientists estimate that there is 165 million tons of plastic swirling about in the oceans right now.   And we are on pace to have more plastic than fish (by weight) in the world’s oceans by 2050. That’s some scary stuff.
