Cyanobacteria (blue-green algae) bloom on Lake Erie (United States) in 2009. These kinds of algae can cause harmful algal bloom. A harmful algal bloom (HAB), or excessive algae growth, is an algal bloom that causes negative impacts to other organisms by production of natural algae-produced toxins, water deoxygenation, mechanical damage to other organisms, or by other means.
When water containing phosphates are washed into water areas, they carry with them fertilizers, nutrients, and wastes. Phytoplankton and algae flourish at the surface due to increased phosphates. Dead phytoplankton and other organisms sink to the bottom giving rise to large numbers of decomposers due to increased food supply (dead organisms ...

Globe at Night is an international scientific research program that crowdsources measurements of light pollution in the night sky. At set time periods within each year, the project asks people to count the number of stars that they can see from their location and report it to the project's website.
Light pollution dramatically reduces the visibility of stars. The visibility of astronomical objects is strongly affected by light pollution . Even a few hundred kilometers away from a metropolitan area where the sky can appear to be very dark, it is still the residual light pollution that sets the limit on the visibility of faint objects.
Visual pollution is the degradation of the visual environment due to unattractive or disruptive elements that negatively impact the aesthetic quality of an area. It can affect urban, suburban, and natural landscapes. [1]
Plastic pollution in the ocean is a type of marine pollution by plastics, ranging in size from large original material such as bottles and bags, down to microplastics formed from the fragmentation of plastic material. Marine debris is mainly discarded human rubbish which floats on, or is suspended in the ocean.
