California voters reject food labeling requirement

The dispute over GMOs has divided organic farmers and food markets. Farms and food producers must earn the right to claim their food is organic or free of chemicals. The largest organic food businesses object to labeling GMOs. They say a food can be natural and organic even if it has been genetically engineered.

Activists say testing is necessary because a food cannot be considered safe until all the risks are understood. Manufacturers base their safety claims on a ninety-day testing period. Activists say the tests are not long enough to show all the possible effects.

For years, wildlife experts have said that tigers avoid living close to people. But a new study disputes the belief that these animals need lots of people-free space.

The study appeared in the Proceedings of the National Academy of Sciences. The findings are considered important because there are only about three thousand two hundred wild tigers in the world. That is a ninety-seven percent decrease since the start of the twentieth century. The drop has been blamed on the ever-rising human population, agriculture and the development of areas where the big cats live.

The study took place in and around the Chitwan National Park in Nepal. The park lies near the Himalayan Mountains. The area is home to about one hundred twenty tigers.

Neil Carter is a graduate student at Michigan State University. His goal was to study how the tigers reacted to people who visited the Chitwan National Park and local villagers. He placed camera traps in eighty different places. He says the images they captured showed intense activity inside and outside the park.
