How tech is tackling wildlife trafficking

In the past, Los Angeles was a dangerous city fraught with gang wars. Lately, though, LA has become a safer city due to six changes enforced by the police cracking down on public violence and gangs.

Chicago is curbing homicides through an anti-violence initiative that uses social networks to rank people’s likelihood of killing and being killed. Police then do home visits and have personal conversations with people of high risk to inform them of consequences of future crimes.

There are only five northern white rhinos left in existence - all in captivity and unable to breed. Researchers work to identify the most valuable solution to rhino poaching in order to prevent the animal from going extinct.

A robust population of grizzly bears can be an indicator of healthy land; however, the bears also can destroy grain bins, consume vegetation, and kill livestock. Ranchers work with the Canadian government and local conservation groups to protect their resources with bear-proof grain bins and electric fences.

The El Paso Times reports from the heart of the Rio Grande Basin - where drought has led to dramatic decreases in water supply, and serious changes in management of river resources are called for - on how the region plans to tackle the effects of climate change. Citizens work to increase water regulations and frugality in order to find a solution to the dwindling water problem.

Population growth, historical dryness and predictions of a warming climate all mean a future of scarce water in the Rio Grande's Upper Basin. Farmers and the irrigation districts are left to try and find ways to conserve what river water they have - and there's a lot to be saved. To minimize such losses, both irrigation districts have taken a number of steps.

In a country of limited resources — and perhaps for that very reason — preparing for natural disasters is top of the agenda in Bangladesh.

Palm Beach County, Florida has many of the same social problems that Philadelphia has, including “gangs, drugs, and poverty.” However, their school system has managed to keep students safe by employing “safe-school case managers” who build relationships with students, and they offer a youth court that is a system run by students who peer-review cases of unrest.

Crushing poverty and extreme violence - fueled by drug trafficking and police corruption - are behind a mass migration of Central American children to the United States in recent months that has overwhelmed U.S. border resources and driven illegal immigration to the fore in U.S. congressional elections. But the United Nations has praised Nicaragua's security model, which includes social services to help youths in gangs find jobs as well as sport programs like little-league baseball teams.

Warming water has led to the collapse of coral reef systems in the western Indian Ocean, essential to fisheries, protecting shorelines, and reducing beach erosion and sea-level rise. Marine scientists from Nature Seychelles, as part of an international project to protect and restore the reefs, are promoting varieties of coral that they have found to be resistant to the rise in temperature.
