This research aimed to identify rural knowledge of harms of the unsafe use of plastics as a dependent variable and its correlation relationship with some rural women respondents distinguished characteristics as independent variables, also to identify their information sources about unsafe use of plastics . - Data were collected through personal interview questionnaire from a simple random sample amounted to 130 rural housewives in Merza village in In AL Mamora area, Alexandria Governorate - Frequencies, percentages, person and simple correlation coefficients and Chi square were used to analyse data and show the results. The results revealed that: - 6.2% of respondents were found in the low level category of knowledge of harms of the unsafe use of plastics. - 36.2% of respondents were found in the moderate (middle) level category of knowledge of harms of the unsafe use of plastics,while 57.6% of the respondents were found in the high level category. - There was a positive significant relationship between the respondent's knowledge of harms of the unsafe use of plastics as a dependent variable and both of respondent's job, respondent's educational status, family type, plastic purchase source, knowledge of illustrated guide and doing handcrafts as independent variables at level of significance 0.01%. - There was a positive significant relationship between the respondent's knowledge of harms of the unsafe use of plastics as a dependent variable and the respondent's age as an independent variable at level of significance 0.05. - There was a negative significant relationship between the respondent's knowledge of harms of the unsafe use of plastics as a dependent variable and both of monthly family income and participation in environmental activities as independent variables at level of significance 0.01%. - According to the respondent's information sources about the results revealed that : Television was come in the first rank (57.4 % ), then the internet come in the second rank ( 60 %), relatives come in the third rank ( 52.3 % ), then radio in the fourth rank ( 33.1 %) then health visitor, rural development an engineer, extention posts and papers and magazines with ratios ( 18.5%), ( 10%), (9.2%) (7.7 %) and ( 6.9%) respectively.

This paper employs Almost Ideal Demand System (AIDS) approach to investigate demand for the most important sources of animal protein in Egypt throughout the period (1997-2019) considering individual incomes and their associated expenditure level. However, animal protein in this study is composed of red meat (Candoz), poultry meat (farm chicken), fish meat (tilapia), eggs and buffalo milk. In addition, it aims to explore their price seasonality. The results suggest that demand price elasticity for red meat, poultry, fish, eggs and milk is inelastic, whereas for income elasticity, it shows that the above mentioned protein sources are necessary goods. Meanwhile, complementary and supplementary relationships haven been revealed among the five sources for cross elasticity. [ABSTRACT FROM AUTHOR]
