HUMAN ACTIVITY AND CLIMATE CHANGE

       "Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to million of years. It may be a change in average weather conditions or the distribution of events around that average."

       Climate change is one of the biggest environmental issues of our time. We people should do something to prevent the irreversible damage to our planet.

       Many factors are contributing to climate change both natural and human-made process (anthropogenic). Climate change occurred due to natural causes but there should be no doubt that it is mainly caused by human activity.  The human influences on climate change arise from changes in land use and combustion of fossil fuels.
 

       Combustion of fossil fuels releases greenhouse gases. Green house gases are gases in the atmosphere that absorb and emit infrared or heat radiation, thus trapping heat in the lower atmosphere. More greenhouse gases, more infrared radiation trapped and held, which increases the temperature of the Earth surface and the air in the lower atmosphere.

       Also, deforestation and various agricultural and industrial practices are altering the composition of the atmosphere and contributing to climate change.

       Human activities have increased in abundance of small particles in the atmosphere, thus, lead to warming and cooling of the climate system.

POLLUTION - ONE OF THE TOP ENVIRONMENTAL ISSUE

       Pollution is one of the environmental issues that has huge impact on the planet and human beings. Water pollution, air pollution, land pollution, and noise pollution are all adversely affecting the environment and people.

       "Water pollution refers to the changes in the physical, biological, and chemical conditions of any body water which harmfully disrupts the balance of ecosystem. It is results by the wastes thrown to any bode of water. The pollutants coming from chemical and industrial processes is one of the major causes of water pollution that has caused serious environmental and health problems. Another causes of water pollution are from pesticides, garbage's specifically plastic, sewage coming from households.

       Meanwhile, air pollution is the introduction of chemicals, particulate matter, or biological materials into the atmosphere that cause harm to human and other living organism and can damage the natural environment. The causes of air pollution may be natural and human. But the majority of them can be attributed to man. Air pollutants came from burning of fossil fuel, exhaust from factories, vehicle, emission and many other. These human activity contributed to the emission of carbon dioxide and greenhouse gases which are the main pollutant that warmth the Earth and pollutes the air that human breathe.

       Also, one of the types of pollution is land pollution. Land pollution is the degradation of Earth's land surface often cause by human activities and their misuse to land resources. Like air pollution and many other environmental problems, causes of land pollution are either natural and human. The causes of land pollution are the increase in urbanization and agricultural land, agricultural and industrial activities and domestic wastes. 

       Another type of pollution is the noise pollution. It is the type of pollution which is distracting, irritating and unwanted sounds. Sounds are considered noise pollution of it disturbs human activity and causes human harm. The usual source of noise pollution are from the traffic noise, industrial activity, human activity and many other. But the main cause of noise is from the 'advancing technology'.

       Environmental pollution have largely affects human life and other living organism. Are we blind, deaf, numb, or fool for us not to see, hear, feel and realize that all of these are caused by US? We are the one who is suffering from our own indifference.Wake up and move because it's not yet too late. Initiate changes for a better world and better future.
