Verrelli spent nine years in Arizona, an arid environment where many organisms struggle to survive, but that has now been altered and made more hospitable by human habitation.

But, experts have also found that many of these cooler, higher-elevation areas — that are more hospitable for Joshua trees — are also susceptible to wildfires because they tend to have denser vegetation.

Unfortunately, as CO2 emissions increase, it acidifies the ocean, which can make it less hospitable for life.

On a deeper level, Frable is concerned about how factors like pollution and climate change are making the ocean less hospitable to aquatic life.

In more hospitable weather, a rat can become pregnant when she’s just two months old, and that pregnancy will last only three to five weeks.
