Environmental science question - Essay ExampleAdditionally, the judicature must consider that very many people or farmers are debate to the idea of incentives thus, it would be proper if for the organisation to abolish the idea completely. Notably, if the government introduces the incentive plan to farmer, it is lively to fail since many farmers will not join such schemes. 2. Why are people willing to accept the hazards of original activities (such as smoking) but not of opposite activities (such as radiation from nuclear testing)? Certain hazards are bearable while others are not. The hazards can be hold backled by human being and targeted only to the personals initiating them are considered bearable hence, for instance, smoking is a single person driven and it cannot affect a vast are or many people at once. On the other hand, hazards related to nuclear testing may be unbearable since the radiation emitted from the same are seeming to affect a vast area and may last for quit e some period (Chiras, 2013). Therefore, nature oriented hazards may be out of control of human control thus, it is always advisable that the same must be avoided at all costs. Moreover, such nature related hazards may affect other thing or natural resources, environment, and human nature as it could have been the original intension. 8.1. Discuss the negative effects of pollutants on crops, forests, and other materials. The effects of taint vary enormously depending on the source of such population and the area it pollutes. However, typesets and crops are affected majorly from air pollution. Dust pollution is unremarkably generated from bear grounds, quarries, and cement works among other industrial activities usually affects crops and other materials from the surface. Other than blocking sun rays, the dust usually blocks stomata thereby hindering their carbon dioxide conductance hence, interfering with plant or crops photosystem II. Pollutant gases like sulphur dioxide and oxid es of nitrogen usually interfere with the growth and development of plants and crops in different ways. For instance, the oxides of both metals usually enter the plants leaves through the stomata from which they go on the same diffusion pathway as carbon dioxide (Chiras, 2013). The oxides of nitrogen then dissolves in the cells giving rise to nitrite ions and nitrate ions that interferes with nitrogen metabolism as opposed to if they could have been absorbed through the plants roots. Additionally, sulphur di-oxide usually causes stomata closure leading to withering of the plants especially crops. 2. Discuss the attributes of successful recycling programmes. Many recycling programs usually fail because of poor recycling or recycling container design. Therefore, effective recycling programs can only be achieved by first specifying the intended material or materials to be recycled before purchasing such materials or containers. Moreover, such containers must be designed properly and must be ergonomically correct. Nonetheless, the recycling containers must as well be designed with several but relevant considerations in mind. Other than the recycling container, recycling program will only be successful if the program first consider and understand the type of the material they intend to recycle (Chiras, 2013).
