In the past, people readily used materials with unknown properties. Sure, they used some durability tests for different materials, but these usually ended with approximate results. Unfortunately, a lot of times this ended in disaster. Furthermore, some materials, although durable and easy to mold, tend to become toxic over the course of the years. In the past, however, this was something that science had no way of determining due to a lack of adequate tools for the job. Finally, there are also hidden properties of materials, such as different behavior under certain climate conditions or external pressure.
According to World Health Organisation statistics, there are around 1 billion active tobacco smokers globally, with high demand earning the world’s 6 largest tobacco firms a staggering $35 billion each year, equating to more than $1000 every second. Even with powerful public health messages about the effects of smoking, both in the developed world and in poorer regions, demand for smoking remains incredibly strong. The health arguments against smoking are well-known and much repeated, but smoking also has some major environmental implications, which are often overlooked. In this article, we examine some of those implications, including land use, paper production, rubbish problems and air pollution.
Despite the controversial debate and various disputes among climate and atmospheric scientists against certain government officials, politicians, or members of the ‘elite’ – global warming is a very real, and quickly rising, global threat.
As the population on the planet rises, resources are being consumed at an astonishing rate. As resources (such as coal-mining, oil-digging, deforestation, industry, among others) increase in demand, our energy output as a whole skyrockets. As global Co2 (carbon dioxide) emissions rise, they get trapped in the upper atmosphere, also known as the greenhouse effect.(1) These gases eventually build up and warm the entire planet, causing permanent and perhaps irreparable damage.
