I hadnt heard this point of view yet. I never saw a desert as something worth preserving, quite the contrary actually. Afforestation projects to green deserts seem absolutely wonderful. Why do you think its a biome worth preserving? Its places hostile to life. Are there negative effects caused by a lack of deserts?

edit: In case anyone else wonders, there would be a negative effect, as deserts are net carbon sinks.

Deserts are often teeming with life. The term refers to rainfall, not population. There are plants and animals equally deserving of protection, and it is worth protecting for the same reason any other biome is. If you look for beauty and balance there you might find it.

Covering them with solar panels disrupts the environment and displaces it’s inhabitants.

> and it is worth protecting for the same reason any other biome is.

Other biomes are worth preserving as they keep this planet habitable. I thought deserts do quite the opposite.

> Even though the plant and animal species that exist in hot deserts are well-adapted to those environments, we know from studies that such organisms are treading a fine line over environmental tolerance; some are even at their limits, according to the IPCC (25).

>Both The Sahara and The Namib are extremely hot deserts and in recent years have experienced some of the hottest temperatures to date. Pakistan and Iran have also experienced record dry spells and high temperatures in the last decade. Even semi-arid desert climates are experiencing an increase in hot and dry spells, becoming more parched and experiencing wildfires in areas where scrub, brush and tree cover is more abundant.

>Evidence demonstrates that the deserts of the Arabian Peninsula alone show increased water vapor feedback, much higher sensitivity, and increased sensitivity in deserts to greenhouse gas emissions. Simply, deserts become hotter and drier during a warming climate with wider implications for the warming climate.

However I was not aware of this

>Many are not aware that deserts are a net carbon sink, providing some relief from the increase in greenhouse gases. This will be problematic while carbon emissions continue to increase, and world governments will need to do something about it in the future. The discovery was made when researching bacteria in the desert. Research suggests that bacteria located in massive aquifers beneath the sand and in the sands itself, are capturing carbon from the air. In theory, the aquifers could hold more than the entire global population of plant material at present at 20 billion metric tons (or 22 billion imperial/US tons) (33).

San Bernardino County is very different from the Sahara and Namib. Take a quick look at aerial images and this is clear.

Sure, the article I linked goes into detail with different desert biomes. Found the cold desert example in Iran especially interesting.

But my question was about deserts in general. The answer I was looking for was deserts being carbon sinks.

Deserts hve unique fauna and vegetation. That alone is a good reason. Also deserts regulate the climate of adjacent and far away regions. For example the Amazon jungle is feed by the Sahara desert [1]

There are a wide range of things that are considered deserts and organisms that live within them. They aren't just empty acres of sand. I'd recommend the Planet Earth episode about deserts to help gain a little appreciation without having to visit one.

They occur naturally and life has adapted to them. From a conservation standpoint that's enough reason for me to keep them around.

When I was a kid, my family moved to Phoenix. On the drive there, I thought the desert was an awful, brown, blasted wasteland. Later on, I went hiking and camping in the desert, and learned a lot about the desert flora and fauna. Gradually my viewpoint changed and I thought the desert was most beautiful.

I’m no wildlife expert, but aren’t there organisms that have evolved to thrive in deserts?
