What is the first thing that comes to a person’s mind when they think of a panda? ‘Adorable!’ ‘Fluffy!’ ‘Cute!’ Unfortunately‚ these lovable creatures are endangered. Threats from China’s human population‚ left over 1‚800 pandas in the world. Development and the increasing human population in China threatens the lives of pandas and leads to their numbers dropping. To help them‚ we should donate money so that we could further their research‚ and the making of panda reserves and bamboo corridors. Developments

processor transistor growth predicted by Moore does not always translate into exponentially greater practical CPU performance. Let us consider the case of a single-threaded system. According to Moore’s law‚ transistor dimensions are scaled by 30% (0.7x) every technology generation‚ thus reducing their area by 50%. This reduces the delay (0.7x) and therefore increases operating frequency by about 40% (1.4x). Finally‚ to keep electric field constant‚ voltage is reduced by 30%‚ reducing energy by 65% and power

How Global Population Growth is Creating Serious Environmental Problems According to Population Connection‚ population growth since the 1950’s is behind the diminishing of 80 percent of rainforests. It also accounts for the loss of thousands of plant and wildlife species‚ and an increase in in green house gas emissions. It also widely believed that population will account for water scaring as well. . IN less developed countries the lack of birth control‚ as well as cultural traditions that

Since 1800‚ the human population has multiplied more than six times. To keep up with the increase in food demands‚ the output of farms and the productivity of farm lands have also increased. The Green Revolution‚ The Industrial Revolution‚ and massive population growth all caused agriculture to change the ways that food was produced. Food production went from a very labor intensive profession to a mostly mechanised industry. Horses were replaced by tractors and farmers planted huge monoculture fields

Title: The effect on the human population of a global infection AIDS stands for Acquired immune deficiency syndrome. AIDS is caused by a virus known as HIV‚ the human immunodeficiency virus. If HIV is contracted the body will begin to make anti-bodies in order to fight the infection‚ if these antibodies are found in the blood the person is known as HIV-positive. HIV causes the immune system to weaken which leads to opportunistic infections that can make the compromised host sick due to the weak

Wildlife includes wild animals and plants collectively. As a human being‚ we need to live in amity with other living things on the Earth. It is glorious that Malaysia is a habitat of much wildlife such as tigers‚ elephants‚ lions‚ leopards and many more. We have to appreciate that our country has such balance ecosystem. It is reported that some wild animals encounter extinction. Those animals mentioned are white tigers. Humans should be blamed causing this problem occurs. Cutting down the
