Drilling may also result in a disruption of migratory pathways, degradation of important animal habitats.

The resulting residue has several compounds containing potential pollutants, which if incorrectly disposed of can pose several risks to terrestrial, aquatic, and aerial environments, including reducing soil fertility, affecting negatively the flora and fauna and causing health problems

However, people still do this due to high demand for energy worldwide.

  1. Water contamination: fracking requires large amounts of water, and natural gas leaks can contaminate nearby water sources with chemicals and pollutants. This can harm aquatic ecosystems and also make it difficult for humans to access clean drinking water.
  2. Greenhouse gas emissions: Natural gas is primarily composed of methane, which is a potent greenhouse gas that contributes to climate change. When natural gas leaks from fracking sites, it can release large amounts of methane into the atmosphere, contributing to global warming and climate change.

    1. 
    1. Oil spills: One of the most significant risks associated with deepwater drilling is the potential for oil spills. Oil spills can have devastating effects on the environment, including harming marine life, damaging ecosystems, and impacting local economies.
    2. Disruption of marine ecosystems: Deepwater drilling can also disrupt marine ecosystems by disturbing habitats, introducing pollutants and chemicals into the environment, and creating underwater noise pollution that can harm or disorient marine life.
    3. Climate change: Like all forms of oil and gas extraction, deepwater drilling contributes to climate change by releasing greenhouse gases when fossil fuels are burned. Additionally, oil spills can exacerbate climate change by releasing large amounts of methane into the atmosphere.
