Are There Ethical Concerns to Mining the Moon?

Moon Express’ ultimate goal is to start mining the moon for precious metals that could be used in everything from electric car batteries to missiles. Moon Express is not the only company considering mining the moon. In fact, NASA is opening up non-financial support to help private companies develop robotic lunar landing capabilities which could ultimately be used for commercial activities as well as scientific and academic research. What do you think is the most important scientific or ethical concern to consider about mining the moon?

Will Crushing Ivory Reduce Elephant Poaching?

Each year, tens of thousands of elephants are being slaughtered due to illegal poaching. Poachers kill elephants for their precious ivory tusks, which are now valued even higher than gold. This past March, over 60 scientists from around the world published a paper titled Devastating Decline of Forest Elephants in Central Africa, which portrays a bleak future for African elephants as a result of this poaching. According to the study, in just nine years the African elephant population has decreased by 62 percent, and African elephants have lost 30 percent of their geographical range. If the current rate of poaching continues, elephants could face extinction in as early as 10 years.

Should We Bring Species Back to Life?

In recent years, scientists have discovered carcasses of frozen woolly mammoths with intact tissues and preserved DNA. With this DNA, and that from other extinct animals, researchers are trying to actually clone the extinct animals and bring them back to life. Current technologies are on the verge of making this possible. So far, the closest we’ve come is to de-extincting the passenger pigeon, thanks to frozen DNA samples and the DNA of its closest relative, the band tailed pigeon.

How Should We Manage Forest Fires?

Wildfires play an important role in a healthy ecosystem. They maintain the ecological integrity by replenishing and rejuvenating the landscape while helping to return nutrients to the soil. At the same time, wildfires can become unwieldy and pose a severe threat to the stability of our communities. After the nation faced massive devastations from unwieldy fires such as the Peshtigo Fire and the Great Fire of 1910, the forest service began implementing strict policies stating that all wildfires were to be quickly suppressed.

Do Now #79: Saving the Honey Bees

Since 2006, honey bees have been dying at an alarming rate. The event, called Colony Collapse Disorder (CCD) has killed about one third of all honey bees within the US. We depend on honey bees to pollinate crops that we eat every day—apples, cucumbers, blueberries, broccoli, onions, pumpkins, carrots, avocados, almonds, strawberries, soybeans, watermelon, and more. The bees’ services are estimated to be worth $20-30 billion in agricultural production annually in the US alone.
