Shifting Sands

Reading the landscape is a development skill taught in middle school Earth science. It is taught to preschoolers by parents. Young minds are open to learning.

The local news reported advancing sand dunes are burying homes. An Earth science lessen is easily forgotten without experiential learning. The dangers of building or buying a home too close to the big lake can be seen during family or school outings. It is a gamble to determine exactly which homes will get buried.

A trip to Lake Michigan’s shoreline dune complex for a swim will be a fun outing where one can see trees buried by moving sand at Hoffmaster State Park or in other parks. Some of the trees have adaptations allowing them to produce adventitious roots from tree trunks as their original roots get buried too deep to survive. The new roots give the tree continued life under tough circumstances.

At some future date, the sand dunes will shift and uncover tree trunks, exposing the roots developed from the growing trunk that was previously high in the air before being buried. If fortunate, the tree will have lived and died before sand is blown away to expose its skeleton.

One might refer to sand dunes as a living, moving, entity, but by reading the landscape, we discover they are not. Moving dunes bring life or death to species by the lake and will crush buildings. Contractors build and sell homes close to the shoreline. They arrive, construct and leave with a profit. The buyer that did not learn to read the landscape might lose their home to the crushing weight of sand depending on where the home was built.

The news showed a cottage that collapsed under the weight of moving sand. People were interviewed about nature’s destroying power. Owners are hiring bulldozer operators to move sand to save homes and resorts. The reporters hoped the home owners would win the fight against nature’s forces.

A fight is not necessary. If the people refused to buy homes close to shore or on shifting dunes, their homes would not be endangered. Many want the shoreline view and are willing to gamble their home’s future. The result is their home might be buried or washed into the lake. A Go-fund-me account has been established to help save homes because people cannot afford to hire contactors to keep moving sand.

Learning the school lessen might have resulted in choosing to live in a safer location. In the 1980’s I observed homes falling into Lake Michigan when high lake levels undercut foundations. I witnessed multi-million dollar homes fall into the Pacific Ocean as erosion undercut cliffs. The homes were too large to move and should not have been built close to the ocean.

Homes are built on barrier Islands along the Atlantic Ocean even though barrier islands are known to move and wash away. Classroom education is valuable but field trip experience is essential for learning to read the landscape. Book learning requires supplemental practical experiences to learn to read the landscape. That is the purpose of places like the Howard Christensen Nature Center and for parents to take families to natural areas.

I began as director at HCNC in 1986 when an Environmental Education Advocacy Council and School administrator agreement required some Kent ISD teachers to bring students to HCNC. I was told HCNC was securely funded by property taxes. As time passed, and shifting sands of education politics changed. I was told environmental education was no longer a priority in America after the early 2000’s presidential election. The Kent ISD stopped funding HCNC. An impact of that decision might result in students losing their homes to nature’s forces when they are grown. We are in a phase of political temperament again when many want to focus only on the present without considering the triple bottom line of economic, social, and environmental impacts for the future. Economic health cannot be sustained without social and environmental sustainability. Security in our personal nature niche depends on the shifting sands of politics and how well people learn to read the landscape to protect their wellbeing and investments.
