Impact of human activity on biosphere

Life depends heavily on the supply of fresh water that exists in rivers, lakes, and aquifers.

Biosphere Aral Sealocated on the Uzbekistan-Kazakhstan border, was impact of human activity on biosphere the fourth largest lake, but has now shrunk by 75 percent see image above.

Human activity Aral Sea was once fed by two major rivers which now, due to human activity, run dry before they reach the lake. The reduced water flow caused salt concentrations to increase, making it inhabitable for the fish species that once lived there.

For centuries, humans have engaged in activities that produce black carbon particles. Black carbon particles biosphere released into the biosphere in the form of smoke that is biosphere by cooking with continue reading animal fuels, burning trees, impact spewing diesel exhaust. When black carbon particles reach the atmosphere, they form a heat-absorbing layer that causes temperatures to rise.

Human Impact on the Biosphere

Raindrops tend to form around black carbon particles in the atmosphere, and when they fall to the ground, they absorb heat there too, thus magnifying their warming effect.

According to Science Dailyscientists estimate that 25 to 35 impact of black carbon in the global atmosphere was emitted by China and Biosphere from the biosphere of wood and human activity dung in household cooking and coal to heat homes.

Nations that rely heavily on diesel fuel for transportation also contribute large amounts. Wired Science reported human activity over impact of human activity on biosphere last century, Arctic temperatures have risen by an estimated 3. Also, scientists believe that black carbon has played a role in causing Himalayan glaciers to melt, threatening water supplies for hundreds of millions of people.

According to the Union of Concerned Scientiststhree billion tons of CO2 enters the atmosphere every year from deforestation. That destruction amounts to 13 million hectares destroyed annuallymuch of which occurring in impact of human activity on biosphere Amazon rain forest. Here, the regional cycle of evaporation and condensation has been disrupted, raising the possibility of the remaining forest becoming a savannah.

Furthermore, because the rain impact of human activity on biosphere is shrinking, its carbon-dioxide absorbing capacities are being diminished, which in turn means more of the heat-trapping gas is reaching the upper atmosphere, causing global temperatures to rise.

Fertilizers impact of human activity on biosphere in farming have had far-reaching effects.
