A pesticide is a substance used to kill a pest, and in a farming context a pest is anything that attacks or competes with crops. Hence, there are many different types of pesticides: for example, insecticides kill insects, and herbicides kill weeds. The chemicals used in pesticides can sometimes be toxic to humans, however, so organic farming endeavours to use natural rather than synthetic substances as pesticides.

Photovoltaics are materials that produce electricity from sunlight. A single photovoltaic cell can be used to power small devices such as calculators; combined in solar panels they can be used to power solar water heating. Most cells are manufactured from silicon.
Industry:Natural environment
Microscopic particles suspended in the lower atmosphere that reflect sunlight back to space. These generally have a cooling affect on the planet and can mask global warming. They play a key role in the formation of clouds, fog, precipitation and ozone depletion in the atmosphere.
