Another ban on neonics

By Leave a Comment

There have been ominous declines in many insect populations.  Chief among them have been declines in pollinators, which have severe consequences for our food supply.  There are multiple possible causes of these declines and undoubtedly several have been involved simultaneously.

A new study on butterfly populations in the Midwest indicates that agricultural insecticides exerted the biggest impact on the diversity of butterfly populations in the Midwest during the period 1998 to 2014.  The biggest culprits were the widely used insecticides called neonicotinoids that are absorbed into the tissues of plants.

Neonics are meant for targeted pesticide use but are often used more broadly, including for corn crops.

Neonics are already well-known to be especially harmful to bees and are gradually being restricted in various places.  Quebec province passed restrictions on neonic-treated seeds in 2019.  Last December, New York signed into law a phase-out of neonic-treated seeds and a ban on non-agricultural uses of them.

Vermont has now become the second state to ban the use of neonicotinoids by virtue of its state legislature overriding a veto from Governor Phil Scott.  The law minimizes the use of neonics by requiring potential users to obtain written exemptions. 

Opponents to neonic restrictions claim that slashing their use will greatly reduce crop yields.  The experience in Quebec over the past five years is that the Canadian neonic restrictions have reduced corn and soybean crop yields by about 0.5%.  As a result of this tiny reduction, there has been a strong reduction in the amount of neonics contaminating waterways.

Balloon release laws

By Leave a Comment

The Florida state legislature has recently passed a law that bans the intentional release of helium balloons outdoors.  It is a rare example of a bipartisan piece of legislation.  Florida is joining six other states that have already enacted balloon restricting laws.

Balloons released into the sky don’t just disappear into the ether.  They often end up in oceans and waterways and the thin material that remains is 32 times more likely to kill seabirds than other types of plastic debris.  Aquatic animals often mistake balloons for jellyfish and fill up on them.   Balloons tied up with ribbons entangle turtles and manatees.  Even grazing cows have died from ingesting balloons.  Balloons contribute to microplastic pollution, which is a growing problem for all living things, including humans.

Other states with balloon release laws are Connecticut, Tennessee, New York, Texas, California, and Virginia.  Details of the laws vary.  They carve out exceptions for specific applications.  They exempt small children.  Some limit the quantity of balloon release.  Others require balloons to be weighted down to prevent them from rising too high.  California’s legislation is aimed at the metallized mylar balloons that have shorted out high-tension electrical wires and triggered wildfires.

The Florida law equates intentionally releasing a lighter-than-air balloon with littering.  It’s a non-criminal offense that carries a fine of $150.

People enjoy releasing helium balloons, particularly en masse.  The spectacle has become part of weddings, gender reveal parties, and even funerals.  But the practice has serious environmental repercussions, and its restriction is being pursued by more and more states and municipalities.

Banning Neonicotinoid Pesticides | Earth Wise

By Leave a Comment

New York’s Birds and Bees Protection Act contains a targeted restriction on neonicotinoid pesticides. These widely-used insecticides are absorbed by plants and can be present in pollen and nectar, making them toxic to bees and other pollinators.

Among the largest applications of neonics (as they are called) has been in the form of coatings on crop seeds, such as corn and soybeans.  In 2019, Canada’s Quebec province strongly limited neonic use to protect pollinators and the environment.  The chemical industry vigorously protested the regulations and claimed that the restrictions would cause the collapse of the grain sector in Quebec.

Seed suppliers began supplying uncoated seeds in 2019 and now there is scarcely any use of coated seeds in the province.  Monitoring of over 1,000 agricultural sites has shown that there have been no crop failures related to the pesticide restrictions.  In fact, use of the neonics had no economic benefits. 

Naysayers warned that even more harmful pesticides or other farming practices would be used instead.  But that hasn’t happened either. Some farmers switched to much safer insecticides and others abandoned insecticide treatments altogether.

New York has faced similar opposition by farmers and chemical manufacturers to the Birds and Bees Protection Act and all of the same arguments that have been proven to be invalid in Quebec are being made in New York.  Most major environmental advocates in the state support the measures embodied in the legislation.  As usual, it boils down to a battle between economic interests and the health of the environment.

California: Drought Or No Drought? | Earth Wise

By Leave a Comment

Just a few months ago, millions of people in California were living under challenging water conservation rules.  The past three years were the driest on record and reservoirs were depleted, landscapes dried up, and the snowpack in the Sierras at very low levels.

But in recent months, a dozen atmospheric river storms have brought huge amounts of rain and snow to the state.  Twelve out of 17 major reservoirs in the state have been replenished, the snowpack is over 240% of normal, and brown hills are blooming once again.

So, is the California drought over?  According to the experts, the answer is:  sort of.

The record snowpack and heavy rains have erased the most severe aspects of the drought in many parts of the state.  Only 9% of the state is now experiencing “severe” or “exceptional” drought, down from 55% last fall.

But the changes are basically all at the surface.  Groundwater in the state is still extremely low and the state’s cities and farms are still using more of it than is appropriate.  The state has been unwisely overusing its groundwater aquifers because of the drought and this one year of heavy rains cannot replenish levels that have been dropping for years.

California has been rolling back many of the most severe drought restrictions that had been imposed but has not entirely lifted the drought emergency status.  Meanwhile, the massive snowpack in the mountains will begin to melt as the weather warms and, in many areas, Californians will face flooding.  Water is a complicated business in California.

Who Can Solve The Plastic Waste Problem? | Earth Wise

By Leave a Comment

Plastic packaging waste is a global problem.  It collects in the oceans, breaks down into microplastics, which are consumed by fish and in turn by people who eat the fish.  Only 14.5% of U.S. plastic waste is recycled.  Most of it ends up in landfills, where is remains undegraded for hundreds of years. 

A new international study explored the global patterns of plastic packaging waste.  The study found that three countries – the U.S., Brazil, and China – are the top suppliers of waste.  In terms of supply, the Americas generate 41% of the world’s production of plastic waste, Europe 24%, and Asia 21%.

That’s the plastics supply.  As far as the consumers actually creating waste are concerned, the Americas represent 36% of the world’s packaging consumption, Asia 26%, and Europe 23%.

Packaging high-protein food such as meat, fish, and dairy is a major contributor to the waste problem.  Plastic for this purpose is hard to replace and international exports exacerbate the problem, accounting for about 25% of plastic packaging waste.

International agreements typically focus on restrictions and fees on production.  But that mostly creates strong incentives to simply relocate polluting activities to developing countries, which is a zero-sum game.  There need to be incentives for consumers to reduce plastic use such as taxes on waste management, refunds on returning bottles, single-use plastic bans, and so on.

Who can solve the plastic waste problem?  Everyone along the supply chain as well as the final consumers have to be part of the solution for reducing plastic waste.

Global Emissions And The Coronavirus Shutdown | Earth Wise

By Leave a Comment

With so much of industry and personal activity curtailed by coronavirus shutdowns across the globe, it is no surprise that greenhouse gas emissions have declined.  According to new research published in the journal Nature Climate Change, average daily global greenhouse gas emissions declined 17% by early April compared to 2019 levels.

If the reopenings around the world continue and the world actually reaches pre-crisis levels by the middle of June, total CO2 emissions for the year would likely end up lower by about 4%.   If various restrictions continue until the end of the year, total global emissions could decline by 7%.

The study analyzed emissions estimates for three levels of coronavirus shutdowns and across six sectors of the economy.  It looked at trends in 69 countries, all 50 U.S. states, and 30 Chinese provinces, representing in total 86% of the world’s population and 97% of global CO2 emissions.

For the first 4 months of the year, emissions from industry declined 19%, the power sector 7%, and public buildings and commerce 21%, compared to last year.  Unsurprisingly, home energy use actually went up by about 3%.

The findings of this study only represent the effects of a short-lived decline in emissions.  As economies open back up, there is no doubt that greenhouse gas emissions will rise back to pre-Covid-19 levels.

The study also reveals that making real changes in emissions will require more than just behavior changes.  Despite billions of people staying home, companies shut down, planes grounded, and cars off the road, we still managed to pump more than 80% of the usual amount of greenhouse gases into the air for the first quarter of the year.

Getting Rid Of Plastic Here And Abroad

By Leave a Comment

Efforts in the fight against plastic pollution are really stepping up these days. 

New York State lawmakers have agreed to impose a statewide ban on most types of single-use plastic bags from retail sales.  The ban would be the second statewide ban after California, which banned the bags in 2016.  Hawaii effectively also has such a ban since all of the state’s counties have their own bans.

The New York ban would begin next March and would forbid stores from providing customers with single-use plastic bags.  There are a number of exceptions, including food takeout bags in restaurants, bags used to wrap deli or meat counter products, and newspaper bags.  New York counties could opt into a plan to charge a 5-cent fee on paper bags, with proceeds going to the state’s Environmental Protection Fund.  Some environmentalists point out, however, that paper bags have their own issues.  While they do decompose in landfills, they have a substantial carbon footprint since they are made from wood and being heavier, they are more costly to ship.  Business groups are concerned about the forthcoming ban based on increased costs.

Meanwhile, European Union member states have reached a provisional agreement to introduce restrictions on single-use plastic products.  In 2021. European citizens will say goodbye to plastic cutlery, plastic plates and plastic straws among other products.

According to the European Commission, plastics make up 85% of beach litter in the Mediterranean.  Large plastic pieces injure, suffocate, and often kill marine animals but microplastics have reached record levels of concentration – over a million fragments per square kilometer – in the Mediterranean.

Both here and abroad, the war on plastics is heating up.

China And Plastic Waste

By Leave a Comment

In January 2018, China enacted its “National Sword” policy which banned the import of most plastics and other materials headed for that country’s recycling processors.  Those processors had handled nearly half of the world’s recyclable waste for the past quarter century.  China took this step because the deluge of soiled and contaminated materials was overwhelming its processing facilities and creating yet another environmental problem for the country, this time not even of its own making.

Prior to China’s ban, 95% of the plastics collected for recycling in the European Union and 70% in the U.S. were sold and shipped to Chinese processors.  A combination of favorable rates for shipping in cargo vessels that carried Chinese goods abroad and low Chinese labor rates made it a very profitable enterprise.

Before China’s ban, only 9% of globally discarded plastics were being recycled and 12% were burned.  The rest ended up in landfills or simply dumped into the environment.  Over the coming decade, as many as 11 million tons of plastic will have to find a new place to be processed or otherwise disposed of.  There is already evidence that plastic waste is accumulating in countries that are dependent on exporting.  In many places, including a number of American cities, there are curtailed collections and new restrictions on what kinds of plastics are accepted.

Some experts are hopeful that China’s ban might actually have an upside if it leads to better solutions for managing the world’s waste.  North America and Europe need to expand processing capabilities and manufacturers need to make their products more easily recyclable.  Mostly, the Chinese ban should be a wake-up call to the world on the need to greatly reduce single-use plastics.

A Big Problem For The Giant Panda

By Leave a Comment

The giant panda, a national icon of China, has been the focus of an intensive, high-profile conservation campaign since the 1970s.  In an update to the IUCN’s Red List of Threatened Species last year, the giant panda had its designation changed from “endangered” to “vulnerable” following a nationwide census that revealed its population was improving.  But it appears as though this conservation success may be short-lived.
