Animal Abuse Resulting from Wildlife Habitat Destruction 257 plants and tiny creatures) Agriculture and mining stand out as two of the most polluting activities here, along with the burgeoning extractive and resources industries and the use of chemicals Corporations are increasingly mining ever deeper into the earth to extract mineral reserves and burying some of the world’s most hazardous waste deep in the ground (e.g., radioactive waste) (White and Heckenberg 2014; see also Stretesky et al 2014) (see Box 2) Box Catchment Run-Offs Affect the Great Barrier Reef Pollution from mining and agricultural activities can have devastating impacts on marine environments, which are also habitats to many diverse species Catchment run-off is having major negative effects on the Great Barrier Reef, situated off the coast of Queensland, Australia As water runs towards the ocean, it collects farm fertiliser, pesticides and soil and flushes these pollutants onto the Reef: ‘The impact on corals and seagrass, and the species that rely on them for food and shelter, is immense’ (WWF 2014, p 119) A recent study pointed out that reef coral cover had halved since 1985 and that more than 40 % of this loss was due to outbreaks of the coral-eating crown of thorns starfish, which are fuelled by fertiliser run-off from farms (WWF 2014, p 119) The consequences of pollution, therefore, are not only demolition of habitat, but provision of an avenue for the advancement of invasive species (see discussions below) Water pollution occurs when contaminants, such as untreated sewerage waste and agricultural runoff containing chemical fertilisers, poison and alter existing surface and ground waters Surface run-off transfers contaminants from one place to another and harmful chemicals which are suspended in the air get dissolved in rainwater and pollute the soil when they come to the earth’s surface in the form of acid rain (Naik 2010) The scope of water pollution extends from small-scale ponds, to inland waterways, estuaries, to lakes and rivers, to the world’s oceans Sea currents transfer pollutants and wastes around the globe Of particular concern is the accumulation of plastics in the world’s oceans (see White 2013) Plastics have been found on beaches, in coastal waters and their sediments, and in the open ocean on the surface as well as in seabeds including the continental shelf Debris has been found in deep water canyons, at abyssal depths The environmental harm stemming from plastics in the ocean varies according to size and composition of the material Threats to biodiversity and individuals manifest in physical damage through ingestion and entanglement in plastic and other debris, and through chemical contamination by ingestion The importation of alien species can also alter endemic community structures of animals In general, ‘potential chemical effects are likely to
