Unnatural Kingdom

cientists are getting very creative with how they can save endangered species now thanks to advances in technology. Like with the Sierra Bighorns. The Sierra Bighorns were prayed on by Lions and at one point their population decreased to around just 100. Started in the early 2000s, people would fire net guns from helicopters to capture Bighorns fitted with collars with GPS and VHF radio transmitters. And then professional hunters tracked and darted every lion in the area to outfit them with collars that carried VHF radio transmitters. After that, Biologists at computer monitors to watch the Bighorn’s movements. So every time a lion kills multiple bighorns in a short period of time, the hunters use VHF radio waves and specially bred Lion hounds to find and kill it. Or you can do something like the Italian farmers who had bears eating their chickens and tearing up their commercial beehives. They put collars on the bears and when they came close to a sensor, hidden guns sprayed them and bright lights and loud sirens blared and scared them away.

    It’s great that they’re trying to bring back the Sierra Bighorns but it’s going to be a while before they’re totally back to normal. Every species should have some differences between them and the Sierra Bighorns aren’t going to be very diverse. It’s going to be growing from such a small population so the gene pool will also be small. But as the population grows so will the gene pool.

Topic 1: Public Health and Topic 2: Energy, Water Stress and Animal Waste Management

Topic 1: Public Health
IFAP facilities can be very harmful to workers, neighbors and even those living far away from the facilities through air and water pollution. The workers and neighbors of the IFAP facilities experience higher levels of respiratory problems. Workers can serve as a bridging population by transmitting animal-borne diseases to a wider population. The meat also has antibiotics in them to stimulate growth which can lead to a resistance in the body. So when you're prescribed antibiotics for something like strep throat, the antibiotics may not work because your body has developed a resistance to it. And a lack of appropriate treatment of enormous amounts of waste may result in contamination in nearby waters with very harmful levels of nutrients and toxins like bacteria, fungi and viruses.

Topic 2: Energy, Water Stress, Animal Waste Management in North Carolina
When large numbers of animals are raised together they're usually in confinement buildings which could increase the likelihood for health issues with the potential to affect humans which could result from disease carried by the animals or their waste. Animal waste could harbor a number of pathogens and chemical contaminants, but it's usually left untreated. Most of the time it's sprayed on the fields as fertilizer but that raises the potential for contamination with the air, water and soil. The water is a big concern. Groundwater contamination can affect drinking water supplies at a huge distance from the source. But there's a use for all that waste. North Carolina has begun using biomass as an energy resource and you can get that from agricultural resources like crops and animal waste.

EROI

1.)  We should use the Tar Sands before the Oil Shale due to the fact that the Tar Sands have a higher EROI.
2.) Both processes use heat. To get oil from oil shale you have to drill a hole 1,000 to 2,000 feet into the ground and then the shale goes to 700 degrees. But when you get oil from the Tar Sands, they’re being heated with steam to get the bitumen out
3. 3) The biggest difference between the two is you get way more oil from the Tar Sands.


44.) If we're thinking long term, offshore drilling is the smartest choice. It's the smartest choice because there's a higher EROI which means we can produce more oil without extra energy.
55.) When I workout I do the easiest workouts first because I'm lazy. But then I'm forced to do the hard ones but it doesn't matter because I'm huge.
