In this topic we are going to address some human- caused factors about wildlife extinction. To be more focus, we will go into detail one topic by one post only. In this post, we are going to examine on population. Human population growth has negative influences on biodiversity in several ways. With huge human population in this earth, our consumption on earth resources will increase rapidly. This phenomenon will directly increase our demand on earth resources for instance; we will need to harvest more timber, catch more fish, plow more land for agriculture, dig up more fossil fuels and minerals, build more houses, and use more water. All of these consumptions impact wild species. According to UN Population Division, there will be seven billion of human in the earth by late 2011. National Geographic Society, 7 billion population, 2011. So how are we going to influence the system of the earth such as ecosystem by the end of 2011?

Again, I would like to stress this issue by giving you an example more specifically on deforestation. The increasing of human population has caused the demand on wood source and land for agriculture such as Southeast Asia (Cambodia, Indonesia, Laos, Malaysia, Myanmar, Thailand, and Vietnam) lost nearly as much forest per year from the mid- 1970s to the mid-1980s, with 4800 square miles per year (1.4 x 106 ha/yr) converted for agricultural use or cut for timber. Rain Forest Report Card, 1998. On the other hand, in Brazil, the Brazilian government reported that the official rainforest deforestation for 2003 was 2,375,000 hectares. That is 5,868,753 acres. A major reason for this has been the increase in a worldwide demand for Brazilian beef. According to the U.S. Department of Agriculture, exports of Brazilian beef increased from 232,000 metric tons in 1997 to 1.2 million metric tons in 2003. In 2001, the percentage of Europe’s processed meat from Brazil was at 74 per cent. Sam Montana. 2009. http://factoidz.com/cutting-down-the-rainforest-have-we- This mean that the huge consumption of food by the population of human had coast the tree cut down for land to feed cow as a protein source for food. So what is the relationship between forest and wildlife? The matter of fact, tree in the forest act an important role as a producer in food chain, it is because photosynthesis is the base of all ecosystems, organisms that photosynthesize are mainly plant and algae known as producer, primary consumer such as deer consume plant and algae as a source of energy and finally secondary consumer such as tiger consume deer to get the energy. It creates a unique way of food web. When the forest is destroyed, the tree have loosen its role as producer and this will give a negative impact on food web as the primary consumer die out because of hunger and the secondary consumer will also die out as a result their insufficient food supply which is primary consumer.
So, the question that I wish you to think about it deeply is the ways of population contribute to this wildlife. Take time to think about it but not to start to save the wildlife until the eleven hour
