Animals were believed to be bound for China, to be sold in wild meat restaurants. Most are listed in CITES (the Convention on International Trade in Endangered Species of Wild Fauna and Flora) which prohibits or restricts such trade.Overkill happens whenever hunting occurs at rates greater than the reproductive capacity of the population is being exploited. The effects of this are often noticed much more dramatically in slow growing populations such as many larger species of fish. Initially when a portion of a wild population is hunted, an increased availability of resources (food, etc.) is experienced increasing growth and reproduction as density dependent inhibition is lowered. Hunting, fishing and so on, has lowered the competition between members of a population. However, if this hunting continues at rate greater than the rate at which new members of the population can reach breeding age and produce more young, the population will begin to decrease in numbers.The habitat of any given species is considered its preferred area or territory. Many processes associated human habitation of an area cause loss of this area and decrease the carrying capacity of the land for that species. In many cases these changes in land use cause a patchy break-up of the wild landscape. Agricultural land frequently displays this type of extremely fragmented, or relictual, habitat. Farms sprawl across the landscape with patches of uncleared woodland or forest dotted in-between occasional paddocks.Wildlife has long been a common subject for educational television shows. National Geographic specials appeared on CBS beginning in 1965, later moving to ABC and then PBS. In 1963, NBC debuted Wild Kingdom, a popular program featuring zoologist Marlin Perkins as host.[8] The BBC natural history unit in the UK was a similar pioneer, the first wildlife series LOOK presented by Sir Peter Scott, was a studio-based show, with filmed inserts. It was in this series that David Attenborough first made his appearance which led to the series Zoo Quest during which he and cameraman Charles Lagus went to many exotic places looking for and filming[9] elusive wildlife—notably the Komodo dragon in Indonesia and lemurs in Madagascar. Since 1984, the Discovery Channel and its spin off Animal Planet in the US have dominated the market for shows about wildlife on cable television, while on PBS the NATURE strand made by WNET-13 in New York and NOVA by WGBH in Boston are notable. See also Nature documentary. Wildlife television is now a multi-million dollar industry with specialist documentary film-makers in many countries including UK, US, New Zealand NHNZ, Australia, Austria, Germany, Japan, and Canada. There are many magazines which cover wildlife including National Wildlife Magazine, Birds & Blooms, Birding (magazine), and Ranger Rick (for children).Mice, cats, rabbits, dandelions and poison ivy are all examples of species that have become invasive threats to wild species in various parts of the world[citation needed]. Frequently species that are uncommon in their home range become out-of-control invasions in distant but similar climates. The reasons for this have not always been clear and Charles Darwin felt it was unlikely that exotic species would ever be able to grow abundantly in a place in which they had not evolved. The reality is that the vast majority of species exposed to a new habitat do not reproduce successfully. Occasionally, however, some populations do take hold and after a period of acclimation can increase in numbers significantly, having destructive effects on many elements of the native environment of which they have become part.This final group is one of secondary effects. All wild populations of living things have many complex intertwining links with other living things around them. Large herbivorous animals such as the hippopotamus have populations of insectivorous birds that feed off the many parasitic insects that grow on the hippo. Should the hippo die out, so too will these groups of birds, leading to further destruction as other species dependent on the birds are affected. Also referred to as a domino effect, this series of chain reactions is by far the most destructive process that can occur in any ecological community.Broadly speaking, there are two approaches to the issue. The animal welfare position holds that there is nothing inherently wrong with using animals for human purposes, such as food, clothing, entertainment, and research, but that it should be done in a humane way that minimizes unnecessary pain and suffering. Animal rights theorists criticize this position, arguing that the words "unnecessary" and "humane" are subject to widely differing interpretations, and that the only way to ensure protection for animals is to end their status as property, and to ensure that they are never used as commodities.The primary federal law relating to animal care and conditions in the US is the Animal Welfare Act of 1966, amended in 1970, 1976, 1985, 1990, 2002 and 2007. It is the only Federal law in the United States that regulates the treatment of animals in research, exhibition, transport, and by dealers. Other laws, policies, and guidelines may include additional species coverage or specifications for animal care and use, but all refer to the Animal Welfare Act as the minimum acceptable standard.

The AWA has been criticized by animal rights groups for excluding birds, rats and mice bred for research, and animals raised for food or fiber as well as all cold-blooded animals.

The Animal Legal Defense Fund releases an annual report ranking the animal protection laws of every state based on their relative strength and general comprehensiveness. In 2010's report, the top five states for their strong anti-cruelty laws were Illinois, Maine, Michigan, Oregon, and California. The five states with the weakest animal cruelty laws were Kentucky, North Dakota, Idaho, Mississippi, and Iowa.

In Massachusetts and New York, agents of humane societies and associations may be appointed as special officers to enforce statutes outlawing animal cruelty.

In 2004, a Florida legislator proposed a ban on "cruelty to bovines," stating: "A person who, for the purpose of practice, entertainment, or sport, intentionally fells, trips, or otherwise causes a cow to fall or lose its balance by means of roping, lassoing, dragging, or otherwise touching the tail of the cow commits a misdemeanor of the first degree." The proposal did not become law.
