WATCH: Enduring the “endless” expansion of the nation’s petrochemical corridor

As mounds of dredged material from the Houston Ship Channel dot their neighborhoods, residents are left without answers as to what dangers could be lurking.

In the course of a century, Houston, once known for its magnolia flowers, turned into the “energy capital of the world.” To many, at 52 miles long and deepening under its 11th expansion, the Houston Ship Channel represents its epicenter.

The channel hosts hundreds of chemical facilities, some of which have years of documented Clean Air Act violations. Amnesty International called the channel a “sacrifice zone” where fenceline communities, made up predominantly with people of color, are disproportionately exposed to pollution. This is seen as the “cost of doing business,” according to the report.

But to people like Juan Flores and his family, the area is also home.

Flores, who you’ll meet in the video report above, has lived in Galena Park his entire life, and has been surrounded by the Houston Ship Channel’s dredge material deposit sites for as long as he can remember. He even recalls playing in them as a child.

The current 11th expansion of the port will create new dredge deposit sites and will stack new dredge material on old sites. In response to communities’ concerns of potential risks, Port Houston, the local entity that manages the public ports of the channel and is in charge of the expansion alongside the U.S. Army Corps of Engineers, has said there is no cause for concern. According to the Corps, the material is tested before being placed on the mounds — yet the Corps has stated in the past that they do not test the deposit sites.

Editor’s note: This story is part of a two- part series that will highlight the expansion of industry along the Houston Ship Channel – and the channel itself – amidst the landscape of an ever growing industrial footprint and the pollution that comes with it.

Toxic chemicals and climate change work together to harm fertility across species

In a recent review published in NPJ Emerging Contaminants, researchers examine how toxic chemicals can reduce fertility in both humans and wildlife, and how these effects are worsened by climate change.


In short:

  • Animals - including insects, fish, reptiles, birds, humans, and other mammals - are constantly simultaneously exposed to synthetic chemicals and the impacts of climate change, including rising temperatures.
  • Both of these stressors can harm fertility, and many of the impacts found are similar across species, such as effects on sperm and eggs.
  • The stress caused by these exposures also impacts overall health, harming animals’ ability to adapt to a changing environment and worsening global biodiversity loss.


Key quote:

“To build a sustainable future, we must recognize that chemicals, once released, don’t simply disappear. Instead, they contribute to the larger issue of driving humanity towards the exceedance of planetary boundaries when considered in combination with climate change and other planetary-level impacts.”


Why this matters:

While climate change and toxic endocrine disrupting chemicals (EDCs) are both individually well-established as health threats, few studies have examined the implications of the widespread simultaneous exposure experienced by humans and wildlife. Many EDCs can also impact health across multiple generations, meaning their harm continues long after the original exposure. To better tackle the issue of EDCs, the authors of this study emphasize the need for strong regulations that address chemicals by class, rather than individually.
