Forest crimes

November 20, 2024 By EarthWise Leave a Comment

Wildlife trafficking is the world’s fourth largest form of organized crime, behind only drug trafficking, counterfeiting, and human trafficking. When we hear about wildlife trafficking, we think of elephant ivory, rhino horns, tiger parts, and the like. But so-called forest crimes, which includes poaching protected trees and illegal logging added up to somewhere between $30 billion and $100 billion during the period 2014-2018. A 2020 report by the United Nations estimated that illegal trade just in rosewoods comprised more than 40% of the value of all trafficked species – animal and plant – during that time.

Even though rosewood comprises multiple tree species, world stocks of nearly all of them have been depleted through overexploitation. Rosewood is now protected worldwide, and some 300 species are under trade restrictions.

With a value of as much as $1.5 million per cubic meter, rosewood is at the center of a great deal of illegal activity, government corruption, and controversy. A shipment of 30,000 illegally felled rosewood logs from Madagascar was seized at a port in Singapore in 2014. Those rosewood logs, worth at least $50 million, have been hung up in multiple legal proceedings and disputes ever since and remain in Singapore.

With huge financial stakes, it is perhaps not surprising that the U.N. estimates that as much as a third of the supposedly legal global timber trade involves illegally harvested wood.

Enforcing the Green Amendment

August 13, 2024 By EarthWise Leave a Comment

In November 2021, 70% of New Yorkers voted to include environmental rights in the Bill of Rights of the New York State Constitution. The amendment recognizes and protects the rights of all New Yorkers to clean water and air and a healthful environment. It places these rights on the same constitutional level as other enshrined freedoms, such as the right to freely speak and the right to be free from unreasonable searches and seizures.

Since its passage, the Green Amendment has been at the center of controversy over how or even whether it is enforced. The state has taken the position that the amendment does not empower citizens to dictate the actions of agencies like the state Department of Environmental Conservation.

A lawsuit filed in 2022 by residents who live near the High Acres Landfill in Monroe County demanding environmental cleanup resulted in a ruling that complying with the Constitution is not optional for a state agency. That ruling was appealed, and the case is currently before an appeals court.

A similar lawsuit is now going on against the state’s largest landfill in Seneca Falls. Once again, the position taken by the state Attorney General is that the Green Amendment does not alter the DEC’s enforcement discretion as to whether to force the landfill operators to take action.

Environmental activists have been staging protests at the state Capital, urging the governor, the state attorney general, and the DEC to shift their approach to applying the Green Amendment. Until this issue is resolved in the courts, it is unclear whether this amendment, put in place by 70% of voters, will actually protect the citizens of New York and its environment.

Chasing The Ivory-Billed Woodpecker | Earth Wise

June 13, 2023 By EarthWise Leave a Comment

The ivory-billed woodpecker is or was the largest woodpecker in the United States. The last unassailable sighting of the bird was in 1944. Since then, there have various reports of glimpses of the bird or of hearing its distinctive sounds. But there has not been anything resembling proof that the bird still exists.

Despite this, the ivory-billed woodpecker has been legally protected under the Endangered Species Act. There has been a proposal to end that protection and formally declare the species extinct. Because of the controversy surrounding the bird, a final ruling on its status has been repeatedly delayed by the US Fish and Wildlife Service.

Very recently, a peer-reviewed study in the journal Ecology and Evolution makes the case that the ivory-billed woodpecker still exists and that it is premature to declare it extinct. The study cites visual encounters by expert observers, audio recordings, tree-damage, and rather grainy video evidence. The authors claim that there is intermittent but repeated presence of birds that at least look and behave like ivory-billed woodpeckers.

One might ask: why does it matter whether this bird is declared extinct or not? The answer is that there are limited federal funds for conservation efforts, and they should be spent on saving genuinely endangered species and habitats. The authors of the new study say that removing federal protection would be bad for any remaining ivory bills, which may be living in some swampy old-growth forests in Louisiana. Other scientists consider conservation resources expended on the ivory-billed woodpecker to be chasing a ghost.

As is the case for several other notorious objects, one really clear photograph of an ivory-billed woodpecker could solve a long-standing mystery.

Plants Make Sounds | Earth Wise

May 9, 2023 By EarthWise Leave a Comment

Some people talk to their plants. It is highly unlikely that the plants are listening, but recent research has found that plants are doing quite a bit of talking of their own.

It turns out that plant emit a variety of click-like sounds, especially when they are stressed in some way, such as being dehydrated or injured. The sounds are actually fairly loud – comparable to the volume of human speech – but occur at frequencies well above the range of human hearing.

The study at Tel Aviv University in Israel monitored plants in a greenhouse that were subjected to various stresses over time. Unstressed plants emitted less than one sound per hour, on average, while stressed plants emitted dozens of sounds every hour.

Recordings of the plant sounds were analyzed by specially developed artificial intelligence algorithms. The algorithms learned how to distinguish between different plants and different types of sounds. Eventually, they could identify the plant and determine the type and level of stress from the recordings. They could even do this in a greenhouse with a great deal of background noise.

The study resolved a very old scientific controversy about whether plants emit sounds. Not only do they, but the sounds contain useful information. We don’t yet know what the mechanism is for plant sounds. It is likely that in nature, the sounds are detected by various animals and perhaps even plants that can detect the high frequencies. And perhaps they react to them as part of seeking food, shelter, or other services that plants provide. Given the right tools, we humans may also be able to make use of the sounds being made by plants.

Life In The Great Pacific Garbage Patch | Earth Wise

June 14, 2022 By EarthWise Leave a Comment

The world’s oceans contain five gyres, which are large systems of circular currents created by global wind patterns and the Earth’s rotation. Gyres act like gigantic whirlpools. Anything that floats into one of them eventually ends up in the center. Ever since floating plastic waste started entering the ocean, it has poured into these gyres and created so-called garbage patches. The largest of these is the Great Pacific Garbage Patch, located halfway between Hawaii and California. According to the Ocean Cleanup Foundation, the Great Pacific Patch contains at least 79,000 tons of plastic.

A recent study has shown that the garbage patch is not just a place where drifting plastics aggregate; it is also a place where drifting animals aggregate.

It turns out that the Great Pacific Garbage Patch is absolutely teeming with life, primarily small surface-dwelling animals that are collectively known as neuston. A ship surveying the garbage patch found that in some places, there were nearly as many neuston as there are pieces of plastic.

Typical creatures in the patch are blue dragon nudibranchs, Portuguese man-o-wars, anemones, sea snails, blue buttons (which are related to jellyfish) and hydrozoans. It appears that these creatures are reproducing within the garbage patch. Little is actually known about the life history and ecology of these creatures, so that studying the garbage patch is offering valuable insights to scientists.

Two nonprofit organizations are working to remove floating plastic from the Great Pacific Garbage Patch. Evidently, removing this existing pollution from the ocean is likely to have unexpected effects on the local ecosystem and is a source of at least some controversy. One thing that isn’t controversial, however, is that we need to stop the flow of plastic into the ocean.
