The Captive Lion Problem | Earth Wise

September 25, 2023 By EarthWise Leave a Comment

In the 1990s, there was rapid growth in South Africa of the private wildlife industry. Large numbers of cattle, sheep, and goat ranchers replaced their domestic livestock with wild animals that wealthy hunters would pay lots of money to shoot. Lions were among the most prized targets for these people. Over time, hundreds of ranchers became involved in the business of breeding large numbers of the big cats in cages or small enclosures. Wealthy clients paid $25,000 to $40,000 to shoot a captive-bred lion – cheaper than the cost of a true wild lion hunt and much easier too. The animals were not afraid of humans and were easy to find.

By 2015, about 200 ranches held at least 8,000 captive-bred lions. Over 600 were trophy-hunted that year, generating about $16 million in trophy fees, mostly from Americans.

Journalists and conservationists exposed poor conditions on many lion farms and many other abuses. Over time, the South African government cracked down on the export of lion bones and other body parts for taxidermy, traditional Chinese medicine, and other uses. The days of captive lion breeding seemed numbered but shutting down the lucrative industry is not easy.

Wild lions in South Africa are not endangered. In fact, existing sanctuaries and preserves have as many lions as they can sustain. What to do with thousands of captive lions is a real problem. Some have suggested mass euthanasia, but that appalling idea has garnered very little support. The future of these animals still hangs in the balance and so far, there are really no truly desirable solutions in the offing.

Endangered Plants And The Changing Climate | Earth Wise

August 31, 2023 By EarthWise Leave a Comment

Plants are a critical resource because of the countless ways they support life on Earth. Plants release oxygen into the atmosphere, absorb carbon dioxide, and provide food and habitat for humans and wildlife. Plants are also used to produce fibers, building materials, and medicines.

Plants form the backbone of natural ecosystems, and absorb about 30% of all the carbon dioxide emitted by humans each year. But plants are struggling to adapt in a human-dominated world. Even though they are easier and cheaper to protect than animals, plants are often overlooked in conservation efforts.

Ironically, conservation efforts appear to be overlooking a key threat to endangered plants. According to a new study led by researchers from Penn State University, all plants and lichens listed as endangered under the Endangered Species Act are sensitive to climate change, but there are few plans in place to address that threat directly.

The threat that climate change poses to endangered plants and lichens had not been thoroughly evaluated in more than a decade. In the study, which was recently published in the journal PLOS Climate, the research team adapted existing assessment tools used to examine the threat of climate change for wild animals and applied them to 771 endangered plant species. The researchers found that all endangered plant and lichen species are at least slightly threatened by climate change, and little is being done to protect the listed species from that threat.

The researchers hope their findings will be used to aid future conservation planning. After all, plants can live without humans, but humans cannot live without plants.

Monitoring Wildlife For Warning Signs of the Next Pandemic | Earth Wise

July 29, 2020 By EarthWise Leave a Comment

According to the World Health Organization, the coronavirus that causes COVID-19 likely originated in wild bats near Wuhan, China, and may have been passed to a second animal species before infecting people. Since then, according to data from Johns Hopkins University, more than 13 million people around the world have been infected by COVID-19 and about 600,000 have died.

But despite the ever-present threat of a new virus sparking the next pandemic, there is currently no global system to screen for viruses in wild animals that could eventually spill over to humans.

In an article recently published in the journal Science, a group of scientists is calling for the creation of a decentralized global system of wildlife surveillance. The establishment of this global system could help identify viruses in wild animals that have the potential to infect and sicken people before another global disease outbreak begins.

According to the scientists, coronaviruses alone have caused outbreaks in humans three times in the last 20 years: SARS (or Severe Acute Respiratory Syndrome), MERS (or Middle East Respiratory Syndrome), and COVID-19.

While it’s impossible to know today how often viruses jump from animals to humans, human activity is making such spillover events more and more likely. For instance, many continue to develop wild animal habitat to build new homes or businesses. Some catch wild animals and re-sell them either for consumption or as exotic pets. Parts from these wild animals are often shipped around the world as trinkets or as ingredients for traditional medicines.

A global system that could identify potentially harmful viruses before they jump to humans is technologically feasible, affordable, and clearly necessary.

The Threat Of Bushmeat Hunting

A recent study has identified the steep decline of more than 300 species of mammals as a result of unregulated or illegal hunting. Humans are consuming many of the world’s wild mammals to the point of extinction.
