Frustrated by an increase in wild boar(野猪) attacks, officials in Hong Kong used bread to attract and trap some of the animals in a district close to the city Press reported. Wild boars can be seen frequently along Hong Kong fuse to obey orders from authorities to stop feeding them because they can gather in large groups and pass along diseases. Attacks by wild boars have also become an increasingly common issue. In an attack last week, a wild boar knocked down a police officer and bit his leg last week before the animal fell from a residential car park and died.

Government data indicates that there are roughly 3,000 wild boars in Hong Kong. They are not a protected species. Though Hong Kong authorities have attempted to naturally cut down the boar population, the Agriculture, Fisheries and Conservation Department said it " could not effectively control the wild pig disturbance." "A large group of wild pigs continued to wander and gather at the site, posing threats to members of the public and road users," a statement from the department read.

Since the attack on the police officer, Hong Kong Chief Executive Carrie Lam has cautioned that the city could impose more severe punishment against people who continue to feed the boars. "I understand that a lot of Hong Kong people love the wetlands and nature. However, we also need to protect public safety.We can't simply sit on our hands while things worsen," she added.

Philanthropic group ADM Capital Foundation, the Hong Kong Veterinary Association and other animal rights organizations have since sent an open letter to the government criticizing its shift in policy to kill the boars. A request by groups including Hong Kong Animal Post and Hong Kong Wild Boar Concern Group said that the measures announced by the agriculture department to regularly capture and put down wild boars "ignore their right to live. This approach is extremely unreasonable and contradicts previous animal management policy principles."

Hong Kong needs legislative reform to deal with the current gaps in existing laws, so that wildlife feeding is an illegal activity, punishment is severe and can be enforced effectively.

Scientists at the University of Washington (UW) have come up with an unusual way to help farmers get information about the plants in their fields. 

Farmers already use drones (无人机) to collect information about their crops. But they can only fly for 10 to 20 minutes, and can only travel for a few miles. Last year, the team at UW showed off "RoboFly", a tiny robot that weighed as much as a toothpick and could fly. But it can't fly far at all and it needs a laser (激光) for power. So the scientists began to think about things that already knew how to fly, which led them to the bumblebees (大黄蜂) that fly all day. Compared to many flying insects, bumblebees are so large and strong as to fly carrying almost as much as their own weight.

The UW scientists created a special device with sensors, a small battery, and a way of storing tiny amounts of information. This "backpack" weighs about as much as seven grains of dry rice.

To track the bee, the scientists send radio signals from several spots along the edges of the field where the bee is. The tiny computer on the bee's back uses the strength of the signals to figure out where it is. The backpack records information about the temperature and light. When the bee return s home at the end of the day, a device can wirelessly download the information the bee has collected. Another device can wirelessly recharge the backpack's battery.

In the UW experiment, the scientists cooled the bumblebees down so that they stopped moving, and then glued the backpacks onto the bees. But it would be difficult for farmers to do the same thing for hundreds of bumblebees. Besides, bumblebees don't live long — about a month. Farmers would need to be careful as the bees got older, otherwise the trackers could die while they are out in the field, leaving the electronic litter behind.

Dallas Zoo

With over 2,000 animals and more than 400 species, the whole family will learn so much about animals and conservation here.

Legoland Discovery Center

When the summer gets hot, it's nice to have some indoor fun with kids. Check out the Legoland Discovery Center, where the whole family can play with LEGO Bricks or take photos with their favorite characters from LEGO films. Relax in the 4D cinema and watch some stellar short, action-packed films. Grab a quick snack at the cafe before letting the kids run wild on the playground.

Dallas World Aquarium

Dallas may not be anywhere near an ocean, but that doesn^'t mean the family can't learn about the fish and mammals that call it home. At the Dallas World Aquarium, which is housed in a couple of old storehouses in Downtown Dallas' West End Historic District, the family can admire colorful fish, sharks and sea animals while walking through the aquarium.

Dallas Arboretum and Botanical Garden

Walk through 66 acres of beautiful parkland, creative nature displays, and an ever-changing selection of art. Children will love exploring the Rory Meyer's Children's Adventure Garden. In addition to an adventure bridge, the garden has various interactive exhibits that teach kids about the science of nature and space. Families with older children might enjoy cooking classes or Thursday night concerts in the arboretum.
