Disappearing wetlands

August 21, 2025 By EarthWise Leave a Comment

More than 170 countries gathered recently to discuss how to save wetlands, which are critical ecosystems.  However, the U.S. was a no-show for most of the summit and Russia said it will withdraw from the wetlands treaty.

Wetlands are a crucial element of all life on Earth, supplying fresh water, oxygen, habitat, and food.  The Ramsar Convention, an international treaty focused on the conservation and wise use of wetlands, is the oldest modern global environmental agreement, adopted in 1971. 

Despite this agreement, since 1970 more than 35% of wetlands have been lost or degraded.  A recent report compiled by more than 60 experts from around the world issued a dire warning that the decline of wetlands spells trouble for global food security, climate stability, and even the capacity for life on Earth to persist.

Sadly, geopolitics have overtaken even the instinct for survival.  Because of a prior resolution to monitor Ukranian wetlands harmed during Russia’s ongoing war there, Russia now intends to withdraw from the treaty.  Meanwhile, the U.S. delegate to the wetlands summit only showed up near the end of the meeting to demand that conference documents make no mention of climate change, diversity equity and inclusion, gender, UN sustainable development goals, or zero growth.

Disengagement by the United States from the world’s increasing and shared environmental problems is a global crisis that only worsens existing global crises.

Carbon Capture In Wyoming | Earth Wise

January 25, 2023 By EarthWise Leave a Comment

Wyoming produces about 40% of our country’s coal and many towns in the state were built because of and make their living from it.  With coal’s plummeting share in the nation’s electricity, there is a great deal of anxiety among residents of those towns.

As carbon dioxide levels in the atmosphere continue to climb, there is a growing sense that cutting emissions will not happen quickly enough and it will be necessary to pull the greenhouse gas out of the atmosphere.  The current long-term government climate strategy assumes that carbon removal will account for 6 to 8 percent of the nation’s greenhouse gas reductions by 2050.

The Inflation Reduction Act passed in August provides $3.5 billion to help build “direct air capture hubs” around the country, with an emphasis on fossil fuel-dependent communities such as many in Wyoming. 

The town of Rock Springs, Wyoming is home to the Jim Bridger Coal Plant. A company called CarbonCapture, Inc., is launching Project Bison, which will build a direct air capture facility outside of town that is set to begin operations next year.  It will initially capture 10,000 metric tons of CO2 per year but plans to expand that to 5 million tons a year by 2030. 

That would be far more than any current carbon capture plant can do. The largest plant in the world, located in Iceland, pulls in only about 4,000 metric tons a year.

There are many problems associated with carbon capture.  It uses up very large amounts of energy, possibly presents environmental problems, and is very expensive.  In short, the technology has a long way to go before becoming viable.  However, this may ultimately be another example where necessity is the mother of invention.

Pesticides And Food Insecurity

A newly released report by the United Nations takes a strong stance against the use of industrial agrochemicals, saying that they are not necessary for feeding the world.  The continued use of pesticides at the rate the world currently does in fact can have very detrimental consequences.
