Plastic bottles are a good place to start – Why do these need to be removed from the environment?
Plastic bottles and bags are one of the scourges of our planet causing huge problems in ecosystems. The physical unsightly nature of plastic bottles and bags washing up on beaches is just the start. There are many areas of the oceans where wind and currents cause greater concentrations to build up for example the Great Pacific Garbage Patch. The effects of plastic and microplastics are still being documented, but there are no positives. The findings so far are worrying. Many studies suggest suggest hormone disruptive chemicals such as PCBs are absorbed by microplastics increasing their concentration. These contaminated microplastics are then eaten by zooplankton and enter the food chain.
There are some initiatives that students may wish to get involved with
Adventure Science is Mapping data of microplastic concentrations in different parts of the world
Their Gallatin River project is here
OceanCleanup is actively removing plastics from the sea using some very innovative ideas. Could this be done on a small scale using recyclable materials?
Plasticbank – Aims to remove plastics and enable people to make money doing so in an innovative way poverty and plastics
