The Rivers Remember What We Forgot

What's happening

A new United Nations assessment has found that migratory freshwater fish populations have declined by 81% over the past fifty years. The study assessed more than 15,000 species and identified 30 flagship species for urgent conservation.

The scale of the collapse is difficult to absorb. Freshwater migratory fish feed 200 million people worldwide. Some species exceed 650 pounds and travel more than 7,000 miles. The golden mahseer, called "the tiger of the river," is woven into the cultural and spiritual life of Himalayan communities. In Europe, fish encounter a physical barrier on average every kilometer.

The primary cause is habitat fragmentation. Dams, infrastructure, and river engineering have severed the routes these species have traveled for millennia. As Dr. Zeb Hogan put it, "Freshwater fish support hundreds of millions of people around the world." Michele Thieme of the World Wildlife Fund identified dams as a central driver: structures that fragment river systems and block the migrations these species depend on to reproduce and survive. One bright note exists: the saiga antelope, near extinction in 2015, has rebounded to over one million through coordinated international effort.

What the text says

The creation account in Genesis gives water a specific role. It is the first habitat God fills with life.

Genesis 1:20-2120God said, "Let the waters swarm with swarms of living creatures, and let birds fly above the earth in the open expanse of sky."21God created the large sea creatures, and every living creature that moves, with which the waters swarmed, after their kind, and every winged bird after its kind. God saw that it was good.

The Hebrew word translated "teeming" is sharats, which conveys explosive, swarming abundance. It describes life so thick it is difficult to count. God looks at this profusion and calls it good. The waters are not merely occupied. They are overflowing.

Psalm 104 expands the picture into a hymn of sustained creation.

Psalm 104:25-2625There is the sea, great and wide, in which are innumerable living things, both small and large animals.26There the ships go, and leviathan, whom you formed to play there.

The psalmist sees the ocean filled with creatures "beyond number," living things both small and great. Leviathan plays in the deep. The verb for "play" is sachaq, the same word used for laughter and delight. The text presents creation as a place where God's creatures move with freedom and joy through the habitats designed for them.

The prophet Habakkuk offers a darker angle.

Habakkuk 1:14and make men like the fish of the sea, like the creeping things, that have no ruler over them?

Habakkuk compares humanity to fish with no ruler, creatures subject to whoever can catch them. In context, this is a lament about injustice. But the image carries a secondary meaning: fish without protection, without anyone responsible for their survival, are consumed.

The migratory paths these species follow are older than any human civilization. They predate every dam, every border, every nation that now blocks their way. When Genesis describes God filling the waters, it describes something that existed before us and was given into our care.

The reflection

A barrier every kilometer. That is the average in European rivers. Not one obstacle to navigate. One per kilometer, for thousands of kilometers, on routes these species have traveled since before the first human city.

The creation texts do not describe a world where abundance is guaranteed regardless of what humans do. They describe a world where abundance is entrusted. The word in Genesis 2 is shamar: to keep, to guard, to watch over. The teeming waters were always someone's responsibility.

An 81% decline is not a trend. It is an emptying. The question the text raises is whether a species made in the image of the Creator will act like it before the rivers fall silent.
