In Kenya, the Sheldrick Elephant orphanage takes care of elephants that have lost their herd as a result of poaching. In 2012, the orphanage had a population size of 387 elephants. Over the next two years, they had 18 pregnant cows birth successfully. Three cows were lost due to complications with their pregancies. They lost 14 more from sickness. They found 57 elephants that required care and were able to release 12 into the wild. All of the elephants are kept in a 225 m 175 m rectangular park. Calculate the population growth, growth rate, per capita growth rate and population density at beginning of the year and end of the year.

Environmental health and hazards

An organism's environment is the environment in which it lives and has an impact on its well-being. The World Health Organization (WHO) defines environmental health as "those aspects of public health, such as quality of life, that are influenced by physical, chemical, biological, social, and psychosocial components in the environment." Environmental health is concerned with both natural and man-made settings in order to enhance public health. Environmental science, occupational medicine, toxicology, and epidemiology are the key subdisciplines of environmental health.
