Final answer:
Life on a space station carries risks such as a hostile environment and weakened human immunity, alongside challenges in obtaining food and managing bacteria growth.
Step-by-step explanation:
The negative aspects of life on a space station include exposure to a hostile environment and the effect on the human immune system, making astronauts more susceptible to illness. Additionally, it is challenging to find food in space, and some bacteria may grow faster in microgravity, posing further health risks. Conversely, there are positive developments, such as increased microbial antibiotic production and the growth of high-quality inorganic and protein crystals that aid scientific research.
