    1. Air, water, land and noise pollution has greatly affected the environment. Environmental pollution has affected humans, animals, plants and ecosystem.
    2. Interference in cyclic flow of materials from abiotic environment to the biosphere and food webs affects ecological balance.
    3. The depletion of ozone layer allows entering of UV rays from sun into the earth’s atmosphere which is associated with a number of health related and environmental issues such as skin cancer, eye damage, The depletion of ozone layer has effects in the form of global warming, which in turn leads to melting of polar ice, which will lead to rising sea levels and climatic changes around the world.
    4. Environmental degradation has a host of negative outcomes that effect human beings both directly and indirectly such as increased poverty, famine, weather extremes and species loss.
    5. Garbage causes damage to local ecosystems, and it is a threat to plant and animal life. For example, landfills serve as a popular dining location for birds and other animals, but some of what they eat can cause diseases.Garbage and liquid waste that end up in water bodies negatively change the chemical composition of the water thereby causing water pollution.
