With Australia’s population at approximately 21 million and counting‚ it is an important challenge for the future of the nation. Over the years‚ there have been many factors that have affected the Australian population and in the future there will be plenty more. During the post-WWII period‚ a catchphrase used by politicians and industrialists was ‘populate or perish’‚ used along with the claim that Australia would not be able to defend itself if under attack. A larger population was argued to help

nutrient concentration on duckweed growth Gina Neonakis Biology 203L:11 Biology 203:10 November 14‚ 2011 Abstract Lemna minor‚ or duckweed‚ is a small plant that floats on the surface of stagnant water that is usually rich in nutrients. Phosphorus is an important macronutrient in the growth of aquatic plants. We tested the effect of phosphorus on duckweed population growth using a control medium rich in nutrients and compared it to the population growth in a medium that lacked phosphorus

Why is population an important topic? The human race has an enormous impact on this planet! We control and modify the Earth more than any other species. How do we meet the needs of human beings and also preserve Earth’s finite resources‚ biodiversity‚ and natural beauty? This is the fundamental question of our time‚ and the challenge is becoming more problematic as we add more people. Meanwhile‚ in every locality‚ it’s important to know how fast population is growing‚ so that we can build sufficient

Ehrlich and Ehrlich‚ in the abstract from “The Population Bomb Revisited”‚ believe that overpopulation is a problem that needs to be constantly addressed for humanity to survive in the long run. On the other hand‚ Furedi shares his views‚ in the article “Really Bad Ideas: Population Control”‚ about how he thinks the people that perceive overpopulation as a hindrance are the real problem here rather than overpopulation itself. Baird‚ from “Population Panic”‚ takes a neutral stand

Introduction The population of human beings on this planet has been gaining exponentially‚ since the dawn of Man. A basic feature of an exponential increase is that the numbers increase faster and faster as the population doubles and redoubles‚ with each doubling occurring in the same amount of time (Wright‚ 2008)‚ As the population continues to multiply‚ so do the impacts upon our environment and surrounding ecosystems. As human populations increase‚ the demands for food‚ supplies‚ and housing

Population and Family Planning Policy in India Population growth has long been a concern of the government‚ and India has a lengthy history of explicit population policy. In the 1950s‚ the government began‚ in a modest way‚ one of the earliest national‚ government-sponsored family planning efforts in the developing world. The annual population growth rate in the previous decade (1941 to 1951) had been below 1.3 percent‚ and government planners optimistically believed that the population would continue

Modelling Koala Populations and Management Strategies In Australia we have many species that we consider pests. Most people don’t consider the koala (Phascolarctus cinereus) to be one of them. Unfortunately in the late 1800’s and the early 1900’s millions of koalas were killed for their thick reddish brown to grey fur making them extinct in the state of South Australia and endangered across the rest of the country. In a bid to reverse this disturbing trend and conserve this clearly vulnerable

Introduction What is population explosion? It is a rapid increase in size of the population caused by such factors as a sudden decline in infant mortality or an increase in life expectancy. One factor to consider is the death rate and birth rate is not in balance. This means that rapidly growth increase was mainly caused by decreased death rate and an increase in birth rate. To the extent the number of birth rate exceeds the number of deaths. Population explosion is one of the serious

India ’s population is in peril. Without the implementation of stringent‚ effective population management policies‚ the country ’s population will rise above 2 billion within the next 20 years (www.fpaindia.com). In the absence of control programs‚ India ’s ever growing population will lead to increased incidents of famine‚ disease‚ environmental stress and result in a severe shortage of housing facilities. However‚ if the Indian government quickly administers population regulations so that couples
