Concrete trees

Uttar Pradesh has a program to plant trees along the borders of highways and cities. As with most schemes in India, it should raise an eyebrow or two. Each tree planted is surrounded by brick and concrete rings just over a meter high. I'm not sure how much the bricks and concrete weigh, or how much carbon was released, but the construction seems an unspeakable waste. Mile after mile of these cylinders, marking the trees planted in the 'green highways' or whatever scheme. Of course in India grazing by road-roaming goats, cows and other animals is a big problem for new trees, but there are other dangers for plants. Sun, drought, disease, sometimes the brick rings are empty for these reason. Standing empty, I've decided to name these cylinders the concrete trees of UP.
