The second reason is that state regulations protect wildlife, so it often illegal for people to possess wild animals, that are, especially, Texas-native wild animals. You cannot possess wild animals native to Texas without some sort of a permit. You also do not need a permit for them.
I think small pets like that can be good first pets for a lot of kids to learn about the care of animals. However, pocket pets are appropriate exotic and wild animals and can be beneficial to teach young people how to care for animals.
Stories can be viewed on the Web at vetmed. For instance, crazy ants have already devastated rainforests on Christmas Island and two outbreaks have occurred around Cairns in recent years. A number of methods and techniques are currently available for the control of feral animals, including fencing, trapping, shooting and poisoning.
The type of control method chosen depends on the target species and the environmental surrounds. The effect of control techniques on non-target native species is an important consideration.

Kudzu is a plant from Japan. It was brought to the Unted States to help stop soil erosion. Kudzu is now a huge problem in some southern states. The plant grows very fast and can completely take over an area and out-compete native plants for space and sunlight.
Beauty Turns to Beast Purple loosestrife was planted in gardens in the U. The plants adapted to their new home and began growing in the wild and crowding out native wetland plants and wildflowers.
One plant the loosestrife drives out is the cattail. Cattails are one of the favorite foods of muskrats. Flooding allowed them to escape and establish reproducing populations in the wild by the early s. Invasive carp are swiftly spreading northward up the Illinois River, and are now on the verge of invading the Great Lakes.
Once established in an ecosystem they are virtually impossible to eradicate. Adult invasive carp have no natural predators in North America and females lay approximately half a million eggs each time they spawn.
Parts of the Great Lakes, including nutrient-rich bays, tributaries, and other near-shore areas, would offer invasive carp an abundant supply of their preferred food, plankton.
Plankton is also favored by most young and many adult native fishes and the voracious carp would likely strip the food web of this fundamental resource. The U. Geological Survey has identified 22 rivers in the U. The brown marmorated stink bug, Halyomorpha halys, is native to China, Japan, and surrounding countries. They were first discovered in the United States in Pennsylvania during the late s, but no one knows for certain how they were introduced to North America. Brown marmorated stink bug BMSB populations are exploding in the absence of their natural predators, and they are quickly becoming a nuisance to people in their homes and to the agriculture industry.
The bugs begin to come indoors, searching for warm, protected areas when outside temperatures turn cooler in the fall. BMSBs feed on host plants by piercing the skin and consuming the juices within; the signs of stink bug feeding appear as "necrotic" or dead spots on the surface. A wide variety of plants are known food sources for BMSBs, including ornamental trees and shrubs; fruit crops like peaches, apples, grapes, and pears; vegetable crops like green beans and asparagus; and soybeans and corn.
Zebra mussels and quagga mussels are virtually identical, both physically and behaviorally. Originally from Eastern Europe, these tiny trespassers were picked up in the ballast water of ocean-going ships and brought to the Great Lakes in the s.
They spread dramatically, outcompeting native species for food and habitat, and by , zebra mussels and quagga mussels had infested all of the Great Lakes.
Now both quagga mussels and zebra mussels have spread to 29 states by hitching rides on boats moving between the Great Lakes and Mississippi River Basins. Artificial channels like the Chicago Area Waterways System facilitate their spread.
These man-made channels act like super-highways and are also a pathway for invasive carp, which are currently spreading towards the Great Lakes.
The quagga and zebra mussels blanketing the bottom of the Great Lakes filter water as they eat plankton and have succeeded in doubling water clarity during the past decade. Clear water may look nice to us, but the lack of plankton floating in the water means less food for native fish. Clearer water also allows sunlight to penetrate to the lake bottom, creating ideal conditions for algae to grow. In this way, zebra and quagga mussels have promoted the growth and spread of deadly algae blooms.
Zebra and quagga mussels harm native fish populations, ruin beaches and attach to boats, water intake pipes, and other structures, causing the Great Lakes economy billions of dollars a year in damage.
