Problem: Child labour:

In 2008, the BBC reported that the company Primark was using child labor in the manufacture of clothing. In particular, a £4 hand-embroidered shirt was the starting point of a documentary produced by BBC's Panorama programme. The programme asks consumers to ask themselves, "Why am I only paying £4 for a hand embroidered top? This item looks handmade. Who made it for such little cost?", in addition to exposing the violent side of the child labour industry in countries where child exploitation is prevalent.

Problem: Hunting:

A scientific study in the journal, Biological Conservation, states that trophy hunting is of "major importance to conservation in Africa by creating economic incentives for conservation over vast areas, including areas which may be unsuitable for alternative wildlife-based land uses such as photographic ecotourism." However, another study states that less than 3% of a trophy hunters' expenditures reach the local level, meaning that the economic incentive and benefit is "minimal, particularly when we consider the vast areas of land that hunting concessions occupy."

How much of trophy hunters expenditures actually reach the local level?

A: less than 3%


Problem: High-definition television:

The massive amount of data storage required to archive uncompressed streams meant that inexpensive uncompressed storage options were not available to the consumer. In 2008, the Hauppauge 1212 Personal Video Recorder was introduced. This device accepts HD content through component video inputs and stores the content in MPEG-2 format in a .ts file or in a Blu-ray compatible format .m2ts file on the hard drive or DVD burner of a computer connected to the PVR through a USB 2.0 interface. More recent systems are able to record a broadcast high definition program in its 'as broadcast' format or transcode to a format more compatible with Blu-ray.

 How doesn't the Personal Video Recorder store content?
