Ecotourism can put wild animals at risk

and has no comments yet.
Ecotourism, in which travelers visit natural environments with an eye toward funding conservation efforts or boosting local economies, has become increasingly popular in recent years. In many cases it involves close observation of or interaction with wildlife, such as when tourists swim with marine animals. Now, life scientists have analyzed more than 100 research studies on how ecotourism affects wild animals and concluded that such trips can be harmful to the animals, whose behaviors may be altered in ways that put them at risk.

World's largest herbivores in danger of extinction due to hunting and habitat loss

and has no comments yet.
Many of the world’s largest herbivores — including several species of elephants, rhinoceroses, hippopotamuses and gorillas — are in danger of becoming extinct. And if current trends continue, the loss of these animals would have drastic implications not only for the species themselves, but also for other animals and the environments and ecosystems in which they live, according to a new report by an international team of scientists.The study, which was co-authored by Blaire Van Valkenburgh, a UCLA professor of ecology and evolutionary biology, was recently published in the open-access online journal Science Advances.

Filtration Systems on School Buses Are Needed to Protect Children from Pollutants

and has no comments yet.
An on-board air filtration system developed specifically for school buses reduces exposure to vehicular pollutants by up to 88 percent, according to a study by researchers at the UCLA Fielding School of Public Health. The high-efficiency cabin air, or HECA, system could help protect the 25 million American children who commute on school buses nearly every day. Children are more susceptible to air pollution than adults because they breathe more quickly and their immune and cardiovascular systems are still developing, said Yifang Zhu, the study’s senior author and an associate professor in the department of environmental health sciences.
