Animal agriculture worldwide encompasses 83% of farmland (but only accounts for 18% of the global calorie intake), and the direct consumption of animals as well as over-harvesting them is causing environmental degradation through habitat alteration, biodiversity loss, climate change, pollution, and trophic interactions. [174]
Noise pollution is especially damaging for marine mammals that rely on echolocation, such as whales and dolphins. These animals use echolocation to communicate, navigate, feed, and find mates, but excess sound interferes with their ability to use echolocation and, therefore, perform these vital tasks. [43]
Noise pollution is widespread, which is mostly a result of transportation networks. [9] Although there are many effects of noise pollution, two specific consequences are adjustments in population distribution and modified animal communication. Birds provide a clear example of both of these consequences.
Noise pollution has also altered avian communities and diversity. Noise can reduce reproductive success, minimize nesting areas, increase stress response, and reduce species abundance. [137] [132] Noise pollution can alter the distribution and abundance of prey species, which can then impact predator populations. [138]
These impacts can be split into operational impacts (fuel sourcing, global atmospheric and localized pollution) and construction impacts (manufacturing, installation, decommissioning, and disposal). All forms of electricity generation have some form of environmental impact, [ 210 ] but coal-fired power is the dirtiest.
Breaking it down by impact category: 98% of the parks they studied suffered from haze pollution, 96% faced ozone pollution that impacts humans and 96% of national parks have plants and animals ...
Plastic pollution has the potential to poison animals, which can then adversely affect human food supplies. [ 161 ] [ 162 ] Plastic pollution has been described as being highly detrimental to large marine mammals , described in the book Introduction to Marine Biology as posing the "single greatest threat" to them. [ 163 ]
Even if we somehow made all the right decisions, many animals would still suffer and die from our extreme impacts on the environment. Still, we should avoid letting the perfect be the enemy of the ...
