Groundwater is, as famously quoted by the Texas Supreme Court in 1904, “secret, occult, and concealed.” Sometimes referred to as “hidden water,” it is out of sight and, therefore, unfortunately, out of mind. However, groundwater comprises 98.7 percent of all the fresh, unfrozen water on Earth. About 40 percent of all surface-water flows in the United States are sourced from innumerable seeps and springs that discharge groundwater into streams and rivers. Groundwater supports 26 percent of the human use of water with 70 percent of it watering crops. As drier areas become drier and droughts increase everywhere, groundwater is expected to make up the difference. Unfortunately, much of the groundwater used across the planet is produced unsustainably. This unsustainable use affects flows to springs, streams, rivers, wetlands, and estuaries that support ecologies as well as human needs. In some cases, such as in the Houston area, groundwater production has caused the land to sink, increasing flooding. In this presentation, Professor Mace will present what he has learned about groundwater sustainability through a report he published late last year title “Five Gallons in a Ten-Gallon Hat: Groundwater Sustainability in Texas” and in a forthcoming book titled “Groundwater Sustainability: Its Birth, Development, and Application.” Listeners will have a better understanding of what groundwater sustainability is, how Texas and the greater Houston area is doing with sustainable groundwater management, and what people can do to achieve groundwater sustainability.

The air quality in Harris County is influenced by multiple sources of pollution, including extensive road traffic, concrete batch plants, proximity to the largest petrochemical industrial complex in the United States, and port activities in the Houston Ship Channel. It is also important to note that environmental risks are not always uniformly distributed in urban areas like Houston, Harris County, and individuals classified with low socioeconomic status (SES) can become overburdened by environmental exposures. One pollutant of interest is particulate matter, specifically particulate matter of size 2.5 micrometers in diameter (PM2.5). PM2.5 is of particular interest because these fine particles pose the greatest risk to human health due to their small size and ability to reach multiple organs. There are long-term and short-term impacts of PM2.5 pollution on the human respiratory and cardiovascular organ systems. These short and long-term impacts may have contributed to poor outcomes following SARS-CoV-2 infection (COVID-19). The COVID-19 Pandemic has impacted us all. An important public health objective is to identify key modifiable environmental factors that may contribute to the severity of the health outcomes related to this disease. Join Rachel White, MPH, PhD (c), University of Texas Health Science Center at Houston, as she takes a deep dive into this topic and discusses how pollution may impact our understanding of respiratory illnesses such as COVID-19.  Time for interactive discussion with the speaker will be provided.  Please register for this talk on www.eventbrite.com at https://www.eventbrite.com/e/is-there-an-association-between-air-pollution-and-covid-19-mortality-tickets-330848455637.

“Green Jobs” are all over the internet. What is the true intention of the term? Clearly, installing solar panels is a green job, but are green jobs limited to renewable energy positions?  Join Steve Stelzer, Program Director of Houston’s Green Building Resource Center, who has researched this subject, for a multi-faceted presentation to help people understand the various green and not-so-green interpretations out there in the job market.  In addition, he has some suggestions for “greening up” one’s conventional job.

Join Professor Robert Mace of Texas State University for a discussion on freshwater scarcity. Growing populations, the ever-present threat of drought, aquifer over-pumping, reservoir sedimentation, and climate change are creating a perfect storm to challenge the resiliency of our water supplies. Since water is needed for human health, agriculture, industry, energy, recreation, and the environment and it takes decades to develop new water supplies, it’s critical for societies to carefully plan for today’s and tomorrow’s water. We all play a role here, whether through giving decisionmakers courage to plan for the future, supporting the development of new water supplies, and using water as efficiently as possible in our daily lives.

Join Professor Hyun-Min Hwang of Texas Southern University as he examines the issue of plastic pollution.    Plastic is a polymeric material, not biodegradable, and may last hundreds of years in the environment. Substantial fractions of plastic waste are disposed of improperly, and are found everywhere, even in the middle of the ocean and deep-sea floor.  Small plastics, known as microplastics, accumulate inside of animal bodies and pass through food chains. Some plastics contain harmful chemicals added intentionally during manufacturing processes. These chemicals leached from plastics can cause toxic impacts on humans and wildlife. Plastic production is fast-increasing, so the amount of plastic waste in the environment will also continuously increase unless we change the way we live with plastics. There are easy-to-follow practices we can apply to everyday life to help protect, preserve, and sustain natural resources. The future is up to us. Join Professor Hwang to consider how we can make the earth a better place to live for ourselves, future generations, and wildlife as well.

Join Professor Gunnar Schade of Texas A&M University to learn about the issue of air pollution. Air pollution is a major factor for public health throughout the world. An increasing human population, increasingly clustered in urban areas, is exposed to a variety of air pollutants. Among the common pollutants, fine particulate matter and ozone exposure dominate health effects, which have become much better understood in the last two decades. While air quality has improved in much of the western world, population growth and the continued usage of fossil fuels to power economic growth has worsened air quality almost everywhere else. As the overwhelming amount of air pollution is caused by fossil fuels, namely their mining, combustion and widespread consumer use, a rapid transition to renewable energy use alongside the “electrification of everything” is expected to near eliminate air pollution as an environmental problem in the 21st century. Whether this can be achieved is therefore closely linked to climate change mitigation via phasing out fossil fuel use in energy production and agriculture.

Join Professor Sylvia Dee of Rice University to consider climate change, its causes, impacts, and solutions.  There is now a long-established global scientific consensus that climate change will damage human and natural systems at high expense. Climate change-induced disruptions to human-environment interactions occur via impacts such as sea level rise, storm surge, tropical cyclones, and degradation of ecosystems and resources.  Earth is already responding more quickly than predicted to rapidly shifting, pervasive radiative forcing. Our species’ future will depend on our ability to adapt to and mitigate this response.  Houston provides a geopolitically relevant model city for the impacts of climate change in low-lying coastal zones in the subtropics, where, globally, the highest development rates are occurring. The increasing frequency of flooding due to tropical storms and extreme rainfall have already cost hundreds of billions of dollars, and pose an existential threat to the nation’s energy security.  Houston is ground zero for the study of the impacts of climate change on coastal cities and energy infrastructure. In cities housing critical hubs for the petrochemical industry, the economic effects of climate change will resonate widely.  In this talk, Dr. Dee will summarize the science of climate change and the social challenges that accompany it, as well as the urgent need for solutions that can be adopted now to mitigate the social and economic consequences of environmental degradation.

Join Professor Kerri Crawford of the University of Houston for a talk on the issue of biodiversity loss.  Our planet is home to millions of species that rely on each other and provide important ecosystem services. Humans, too, rely on nature — but we take a disproportionate amount of the resources and modify the environment in ways that negatively affect other species. Our effects on the environment are directly causing what many have termed “the 6th mass extinction.” In this presentation, Dr. Crawford will provide information on what biodiversity is, how quickly we are losing biodiversity, why biodiversity is important for us, and what is being done to protect biodiversity.  Time for interactive discussion will be provided after her talk.  Register for this talk on www.eventbrite.com. All registrants will receive a recording of the talk afterward.  Contact Lisa Brenskelle at gcs.lrc@gmail.com for more information.

Heat is the greatest weather-related disaster in the U.S., killing more people than any other kind of natural disaster.  And, Texas is one of three states with the highest heat-related deaths. A study found that the Houston area averaged 18 dangerously hot summer days per year from 1975 to 2010. Without any action to combat urban heat, Houston’s annual number of days hit by dangerous summer heat could rise to 80 by 2046. So, Houston’s urban heat issues are already serious and are forecasted to get much worse with the Climate Crisis. Urban heat negatively affects human and biodiversity health throughout the region, exacts a financial toll, leads to higher ozone levels, and reduces quality of life.  Heat mapping in Houston has shown that high heat is more concentrated in underinvested communities and/or Communities of Color, thereby widening historic inequalities. Fortunately, there are solutions that can be brought to bear to reduce urban heat.  Join Jaime Gonzalez of The Nature Conservancy, who led heat mapping efforts in Houston, for a discussion on the findings, their justice implications, solutions, and how houses of worship/people of faith can engage.  Learn more/register on www.eventbrite.com.
