Limited cognition barriers are barriers that arise from a lack of knowledge and awareness about environmental issues. For example, with a key environmental issue like climate change, a person might not engage in pro-environmental behaviour because they are: unaware that climate change is occurring; or aware that climate change is an issue, but are ill-informed about the science of climate ...
The effects of concern aren’t limited to reproductive effects, which have obvious implications for population vitality. For example, frogs exposed to pesticide-levels found in the environment demonstrate hyperactivity, whip-like convulsions, and depressed avoidance behaviour, which may increase their vulnerability to predation.

This is an alphabetical list of environmental issues, harmful aspects of human activity on the biophysical environment. They are loosely divided into causes, effects and mitigation, noting that effects are interconnected and can cause new effects.
Human impact on the environment. From top left, clockwise: satellite image of Southeast Asian haze; IAEA experts investigate the Fukushima disaster; a seabird during an oil spill; depiction of deforestation of Brazil's Atlantic forest by Portuguese settlers, c. 1820 –25; acid mine drainage in the Rio Tinto; industrial fishing in 1997, a practice that has led to overfishing.
Further, these issues can be caused by humans (human impact on the environment) [2] or they can be natural. These issues are considered serious when the ecosystem cannot recover in the present situation, and catastrophic if the ecosystem is projected to certainly collapse.
Solutions have a tradeoff, sometimes environmental, sometimes human, sometimes both. For example, moving to a world of all electric vehicles will require huge amounts of minerals that must be dug ...
An environmental disaster or ecological disaster is defined as a catastrophic event regarding the natural environment that is due to human activity. [2] This point distinguishes environmental disasters from other disturbances such as natural disasters and intentional acts of war such as nuclear bombings .
Despite this general lack of a singular theory, some of the approaches noted above indicate certain theoretical preferences. For example, as noted, the political economic approach to green criminology develops explanations of green crime, victimization and environmental justice consistent with several existing strains of political economic ...
