Animal Protection, Welfare and Behaviour

Animals are multicellular eukaryotic organisms that form the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, reproduce sexually, and grow from a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from 8.5 millionths of a metre to 33.6 metres (110 ft) and have complex interactions with each other and their environments, forming intricate food webs. The study of animals is called zoology.

Welfare is the provision of a minimal level of well-being and social support for citizens and other eligible residents without sufficient current means to support basic needs. In most developed countries, welfare is mainly provided by the government from tax revenue, and to a lesser extent by NGOs, charities, informal social groups, religious groups, and inter-governmental organizations.
