Air pollution often exacerbates respiratory disease by permeating into the lung tissue and damaging the lungs. [70] Despite the wealth of environmental consequences listed above, local US governments tend to support the harmful practices of the animal production industry due to its strong economic benefits.
It has the capacity to spread zoonotic diseases to humans, as well as contribute to local extinction. The pathogens to humans may be spread through small animal vectors like ticks, or through ingestion of food and water. Extinction can be caused due to non-native species being introduced that become invasive.
Loss of biodiversity also means that humans are losing animals that could have served as biological-control agents and plants that could potentially provide higher-yielding crop varieties, pharmaceutical drugs to cure existing or future diseases (such as cancer), and new resistant crop-varieties for agricultural species susceptible to pesticide ...
In 2012 there were 5,196 animals and 6,789 plants classified as vulnerable, compared with 2,815 and 3,222, respectively, in 1998. [1] Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically.
Humans have been the cause of many species’ extinction. Due to humans’ changing and modifying their environment, the habitat of other species often become altered or destroyed as a result of human actions. [25] The altering of habitats will cause habitat fragmentation, reducing the species' habitat and decreasing their dispersal range.
The pollution often comes from nonpoint sources such as agricultural runoff, wind-blown debris, and dust. These nonpoint sources are largely due to runoff that enters the ocean through rivers, but wind-blown debris and dust can also play a role, as these pollutants can settle into waterways and oceans.

Marine conservation is informed by the study of marine plants and animal resources and ecosystem functions and is driven by response to the manifested negative effects seen in the environment such as species loss, habitat degradation and changes in ecosystem functions [1] and focuses on limiting human-caused damage to marine ecosystems ...
Coastal wetlands also reduce pollution from human waste, [41] [42] remove excess nutrients from the water column, [43] trap pollutants, [44] and sequester carbon. [45] Further, near-shore wetlands act as both essential nursery habitats and feeding grounds for game fish , supporting a diverse group of economically important species.
