Part One素材段落
In 1973, the Indian government initiated a tiger protection campaign called ‘Project Tiger’ which was designed to help protect the diminishing tiger population. The tiger population was declining due to habitat loss, poaching and other human-related factors. During the campaign, twenty-five tiger reserves were established where human development and inhabitation was forbidden. On these reserves, the breeding of tigers has been facilitated, and mature tigers have been transported to other regions with the goal of increasing their worldwide population. At the same time, the campaign has organized the Tiger Protection Force to catch poachers and relocate villagers in the rural areas so that they are no longer living within natural habitats. As a result of these efforts, the population of Bengal tigers in India has increased from about 1,200 in 1973 to an impressive 3500 in 2007. Due to this fact, they are no longer on the brink of extinction.

Part Two素材段落
Conventional agricultural practices contribute to water pollution affecting both our health and the environment. Only 1% of the pesticides applied to crops actually reach the pests they target, while the remaining 99% of these chemicals enter the environment. The contamination of soil and groundwater changes our terrestrial and aquatic environment and poses a threat to native wildlife. Many species are dependent on clean water and are now endangered because of contaminants in the water. For example, synthetic fertilizers have resulted in an 8,000-square-mile ‘dead zone’ in the Gulf of Mexico where thousands of fish have perished due to oxygen deprivation. Contradictorily, organic agriculture usually uses animal manures as fertilizers which tend to enhance the soil structure as well as reduce the risk of groundwater pollution.
