The livestock enterprise has numerous and diverse impacts on the environment. In a cross-sectional have a look at the usage of an online questionnaire, 361 college students were asked approximately their know-how, attitudes, and conduct related to the environmental impact due to cattle enterprise. The statistics were analyzed using correlations, t-tests for impartial samples, and linear regression fashions. We located that scholars have nearly no know-how approximately the environmental impact of the meals they eat, their attitudes are fairly pro-environmental, yet they may be not strict about pro-environmental conduct. Students with better levels of environmental expertise validated extra pro-environmental attitudes and behavior; attitudes mediate the connection between degree of know-how and behavior with admire to environmental pollutants due to the livestock enterprise. In addition, members that rear/reared animals proven extra understanding and pro-environmental attitudes and conduct, and ladies validated more seasoned-environmental attitudes and conduct than men. There is a want to raise attention of the environmental and health influences caused by cattle industry. An introductory direction on environmental science should be integrated into special academic have a look at programs. Further studies should be performed amongst additional population sectors.

1.1. Literature Review
Production of food from animals has expanded during the last one hundred years, in reaction to growing demand . Throughout the world about 70 billion animals are reared as domestic animals yearly, with more than 6 million animals killed for food each year , and about 56 billion mammals and birds slaughtered every yr . According to a file by means of the Food and Agriculture Organization (FAO) of the United Nations, titled, “The Long Shadow of the Animal Industry” , international meat intake doubled in the course of the duration 1980–2002. According to future predictions, worldwide meat manufacturing is anticipated to double from 229 million tons in 1999 to 465 million lots by using 2050. Milk manufacturing is expected to boom from 580 to 1043 million lots . Besides the humane factors related to the rearing and slaughtering situations of animals within the food enterprise, the terrific increase within the consumption of animal products has a most excessive impact on the environment. The FAO record states that “The meat industry has a marked impact on a standard international scale on water, soils, extinction of plant life and animals, and intake of herbal sources, and it has a sturdy impact on global warming” .
1.2. The Impact of Animal Product Consumption on the Environment
The livestock enterprise is the source of a large spectrum of environmental affects . The first and most essential is weather change . In the 1/3 chapter of the FAO record  it’s miles anticipated that 18% of global greenhouse gasoline emissions are as a result of the farm animals enterprise. The quantity of carbon dioxide (CO2) launched to the surroundings is estimated at approximately 7516 million tons in keeping with year [1,3]. According to Goodland and Anhang  this estimate is too low. According to their calculations the worldwide farm animals enterprise is answerable for at least fifty one% of the greenhouse gases emitted to the ecosystem and the quantity of carbon dioxide is estimated at 32,564 million heaps. This massive distinction stems partly from the FAO using previous resources from the years 1964–2001. Nevertheless, although greenhouse gasoline emissions are expected at handiest 18%, the cattle enterprise is still the second-largest polluter after the strength industry, and more polluting than the transportation industry, which contributes about 13% .
