This was really exciting to see.. When any form of environmental degradation occurs in an area, species that cannot survive die off and some go into extinction. What are the 4 major Click to see full answer. Natural causes of environmental degradation include: An earthquake is the shaking caused by the rupture (breaking) and subsequent displacement of rocks (one body of rock moving to another) beneath the Earths surface. Reduced streamflow in rivers and lower water levels in reservoirs, lakes, and ponds are caused by drought. The economic impact can also be in terms of the loss of the tourism industry. This happens as a result of seismic waves passing through the earth. Floodwaters detrimental effects on coastal marine environments are mostly caused by the addition of too much silt, too many nutrients, and contaminants such as chemicals, heavy metals, and trash. Here is a list of 35 environmental non-profits worth supporting. The images below the line represent some of the 96 percent of marine species that died during the event. The dirty and disease ridden conditions that animals are forced to endure when farmed also encourages the outbreak of deadly pathogens in farmed animals, which can easily be spread to wildlife, and lead to massive species loss. And, when species become endangered, its a sign that an ecosystem is out of balance. The effect that climate has on extinction is very big. Natural Disasters such as volcanic eruptions, The extinction of any species is an irreversible loss of part of the biological richness of the Earth. Species loss occurs naturally over millions of years, and is a normal part of evolution.
