thumb|upright=1.35|Household items made of various types of plastics Plastics are a wide range of synthetic or semisynthetic materials composed primarily of polymers. Their defining characteristic, plasticity, allows them to be molded, extruded, or pressed into a diverse range of solid forms. This adaptability, combined with a wide range of other properties such as low weight, durability, flexibility, chemical resistance, low toxicity, and low-cost production, has led to their widespread use around the world. While most plastics are produced from natural gas and petroleum, a growing minority a

Fishing is the activity of trying to catch fish. Fish are often caught as wildlife from the natural environment (freshwater or marine), but may also be caught from stocked bodies of water such as ponds, canals, park wetlands and reservoirs.
