Pollution

1. Desertification

1.1. Desertification is a type of land degradation in drylands in which biological productivity is lost due to natural processes or induced by human activities whereby fertile areas become increasingly more arid.

1.2. In Asia, Iraq has lost over 70 percent of its irrigated land to salt accumulation. In Russia, much of the irrigated land located where the Volga River runs into the Caspian Sea may last only until the middle of the 21st century before the buildup of salts makes it virtually unusable.

1.3. Adjust human cultivation methods and regions, encourage tree planting

2. Deforestation

2.1. Deforestation is the permanent cutting trees to make room for the space outside the forest. Many countries are still deforestation, resulting in climate change and changes in the geographical environment. Because there is not enough afforestation after deforestation, the result is destruction of water and soil, climate change, reduced species diversity and reduced quality of life.

2.2. In countries like Uganda, people rely on trees for firewood, timber and charcoal. Over the past 25 years, Uganda has lost 63% of its forest cover, Reuters reported. Families send children — primarily girls — to collect firewood, and kids have to trek farther and farther to get to the trees. Collecting enough wood often takes all day, so the children miss school.

2.3. Establish legal provisions that stipulate the amount of felling and encourage students or volunteers to participate in tree planting activities

3. The Greenhouse Effect

3.1. The greenhouse effect is a natural process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases.

3.2. Since the Industrial Revolution in the late 1700s and early 1800s, people have been releasing large quantities of greenhouse gases into the atmosphere. That amount has skyrocketed in the past century. Greenhouse gas emissions increased 70 percent between 1970 and 2004. Emissions of carbon dioxide, the most important greenhouse gas, rose by about 80 percent during that time. The amount of carbon dioxide in the atmosphere today far exceeds the natural range seen over the last 650,000 years.

3.3. Buy items with less packaging, don't buy items for the beauty and gorgeousness of packaging. Classify garbage in the home, recycle recyclable garbage and reuse it

4. Ozone Depletion

4.1. The Earth's ozone layer protects all life from the sun's harmful radiation, but human activities have damaged this shield. Less ozone-layer protection from ultraviolet (UV) lightHelpUVUltraviolet radiation is a portion of the electromagnetic spectrum with wavelengths shorter than visible light.

4.2. Arctic ozone decreases of as much as 40 percent have been measured. This thinning typically occurs during years when lower-stratospheric temperatures in the Arctic vortex have been sufficiently low to lead to ozone-destruction processes similar to those found in the Antarctic ozone hole.

4.3. Check air conditioners, refrigerators or other refrigeration equipment to prevent refrigerant leakage. Reduce the use of chemicals, including weed and insecticides for crops

5. Acid Rain

5.1. The ecological effects of acid rain are most clearly seen in aquatic environments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife. As it flows through the soil, acidic rain water can leach aluminum from soil clay particles and then flow into streams and lakes.

5.2. Covering areas of the Czech Republic, Germany and Poland, the Black Triangle is an area that received heavy acid rain throughout the 1970s and 80s. In parts of the Black Triangle, entire forests were dead or dying and even railroad tracks were being corroded by the acidic precipitation.

5.3. Reduce the use of fossil fuels and use renewable energy, such as solar or wind energy, to reduce pollution

6. Air Pollution

6.1. Air pollution is a mixture of solid particles and gases in the air. Car emissions, chemicals from factories, dust, pollen and mold spores may be suspended as particles.

6.2. In London, England in 1952 when thick, deadly pollution known as the Great Smog, caused by people burning coal in home fires and coal-fired power plants, killed over 4000 people (the official death toll at the time, though later estimates suggest many more).

6.3. Reduce the use of vehicles, travel in an environmentally friendly way, take a bus or bike. Prohibit the burning of garbage, and manage the factory to emit harmful gases

7. Water Pollution

7.1. Water pollution is the contamination of water bodies, usually as a result of human activities. Water bodies include for example lakes, rivers, oceans, aquifers and groundwater.

7.2. The river “Yamuna India”, which takes over 70% of sources of New Delhi”s water supply, is a perfect example of a polluted river. The water contamination of this Indian river is horrible. Death, disease, cancer, organ damage appears in people’s life because of the river. Not only the pesticides cause the pollution of river, the heavy metals, such as copper, lead, zinc and nickel are also the causes.

7.3. Reduce the use of plastics and manage factory sewage discharge and rainwater recycling. The most important thing is to promote water conservation, everyone does not waste water
