Aquaculture - 4Habitat DestructionDeforestation for land and space= CO2
Habitat Fragmentation
Chemical waste - 5Extraction of natural resourcesMining= soil erosion
Sand extraction= altered volume and flow - 6Acid RainCombustion of fossil fuels

Acid rain p.H= 4.2-4.4
Effects on soil= acidic, leached nutrients and intoxicated with heavy metals. - 7Destructed Food ChainsExtinction= disrupts the ecosystem
Hunting and poaching
Excessive grazing
Overbreeding
Migration of animals - 8PlasticsLandfill
