Pollution and depreciation of resources  All living things produce metabolic waste.  In animals and humans the waste material for this is in the form of gas, feces and urine, a very common gas formed is CO2 which enters the air and does not cause problems due to its low levels.  Other gases that often form are H2S that smell bad and are formed in the process of decomposing organic matter, for example at the time of decomposition of waste.  The gas is a pollutant that is found in many places.  Waste material is generally called waste.  Waste from households is often called domestic waste.  Waste from restaurants and hotels, because it resembles household waste, is often called domestic waste.  Waste, especially domestic waste, is actually also food for certain organisms, for example, CO2 is a staple for photosynthesis of green plants.  From CO2 gas and H2O water, sugar and O2 are formed.  O2 gas we need for our breathing.  So nature, in this case plants, from CO2 gas and H2O water,

In nature there are ecological processes that underpin our lives.  Damage to the ecological process will endanger life on Our Earth.  Energy for the ecological process is obtained from the sun.  Below are described some of the most important processes. • Photosynthesis  Photosynthesis is an essential process for maintaining survival on earth.  Photosynthesis is mainly carried out by green plants.  In this process the sun's energy is converted into chemical energy contained in plant organic matter.  This energy is used for the life of other living things that cannot carry out photosynthesis, including humans, animals and microorganisms  Photosynthesis also produces oxygen gas (O2).  Oxygen gas is essential for breathing many types of creatures, including humans.  Without oxygen in a short time humans will die.  Life in water is also supported by photosynthesis.  Photosynthesis is carried out by a ton bank of single-celled plants that float in water.  Plankton is a fis
