As you know, one Of the greatest problems that the world is facing today is that of environmental pollution, increasing with every passing year and causing grave and irreparable damage to the earth….. The main purpose The length of the presentation and the main parts ( Our presentation will last in about 20 minutes . There are four parts and each people will present one part) If you have any questions, please feel free to interrupt me, but I should also say there’ll be an opportunity to discuss issues at greater length after my talk.

Now, let’s start the Part l. 2. Body: Part 1: Real Situation: There are three kinds of pollution: Water pollution : In many places, the water quality has been highly degraded; parameters such as BODE, COD and concentrations of NH, N and P have been found to be by any times higher than the permitted levels. Surface water pollution in rivers, lakes, canals and cities continues to increase.. Coastal water: Pollution from oil, heehaw; metals and suspended solids has been found to exceed the permitted level in many coastal areas.

Land pollution: Land degradation appears to be a prevailing trend throughout the country as a result of erosion, leaching, loss of organic material, droughts, floods, land slides and subsidence, salt intrusion and illumination. Soil degradation has exhausted many areas and even led to desertification in some places. The over- and issue of chemicals and pesticides in agriculture pollute and degrade many areas nationwide.

Air pollution: almost cities are polluted dust, many places are polluted dust very serious air pollution serious from gas emissions from factories and industrial parks… Parameters such as CA, SIS,NON have been found to be by many times higher than the permitted levels. With each kind, we have some pictures, figures, examples. Part 2: Reasons and Consequences: Reasons: Water pollution: is usually 2 reasons: Water pollution comes naturally: Due to rain, snow melt, wind storms, flooding into the dirty waste water, organisms and harmful microorganisms including their corpses.

Water pollution comes from artificial origin : from process of toxic waste in liquid form mainly as domestic waste, chemical and industrial waste water, fertilizer and chemical fertilizer or animal waste in agriculture and transports in the seas with oil spill. Soil pollution: The causes of land pollution also include the garbage that is dumped every day, either into the streets, or into ground. Most of the materials like food leftovers, glass, plastic and all kinds of paper are not used up or recycled. Drive through any industrialized city and you will see factories still spewing pollution into the air and onto the land.

Factories that produce products made of metal, those making plastics, big animal farms, and even nuclear waste disposal activities are causes of land pollution. With growing human population, demand for food has increased considerably. Farmers often use highly toxic fertilizers and pesticides to get rid off insects, fungi and bacteria from their crops. Land pollution is also caused by deforestation which is the cutting down Of trees industrial waste such as nuclear substances mining and even some forms of mechanization.

Air Pollution: Consider a typical manufacturing plant: You will notice that there are long tubes (called chimneys) erected high into the air, with lots of smoke and fumes coming out of it. Waste incinerators, manufacturing industries and power plants emit high levels of carbon monoxide, organic compounds, and chemicals into the air. This happens almost everywhere that people live. After the industrial age, transportation has become a key part of our lives. Emissions from automobile and cars engines contain pollutants. There are aircraft diesel and railroads.

Crop dusting, fumigating homes, household cleaning products or painting supplies, over the counter insect/pest killers, fertilizer dust emit harmful chemicals into the air and cause pollution. Air becomes polluted with noxious gases or black carbon particulates are released into the air. Consequences of pollution : Humans: pollution is bad for our health it kills millions of people each year who get heart disease, skin diseases , lead poisoning and even some lung problems Animal: Pollution can cause declines in biodiversity , negatively effects development of marine organisms ,cause the death of fishes ,affect reproductive processes.

Trees and plants: Pollution will kill trees ,destroy the leaves of plants ,can alter plant metabolism and reduce crop yields Trees and plants: may absorb soil contaminants and pass them up the food chain. The earth: can ruin our ozone layer , cause the worth ‘ s global warming , a harmful greenhouse With this part, we also have some pictures, figures and examples. Part 3: Solution: You have just followed three parts and I think that you may be understand he problems of environment pollution nowadays.

How do we do to protect environment and make it be fresh? It is quite simple and easy. Solution: Reducing waste: reducing waste for instance you can reduce the amount of waste you create by choosing what rubbish you throw away and buy products that can be reused. Moreover , buy products with little packaging especially for those items you use regularly. This will save your money as well as reduce waste. Therefore, think before you throw! Reusing waste: reusing waste any items can be re-used, including mobile phones, computers, clothes ND so on.

Even if you have finished with something, someone else will often be able to use it. Recycling: recycling is processing materials used into new, useful products. Recycling also uses less energy and great way of controlling air, water and land pollution. Planting tree: planting tree is helpful thing. Trees act as natural air filters and improve air quality by trapping CA from the atmosphere and giving us oxygen, and by reducing ozone levels in busy urban areas. Trees also act as natural land erosion shields, by storing water and breaking the impact Of rain as it falls.

Finally, We must be aware Of environmental protection because we are polluters. 3. Conclusion: Summonses: In our presentation, we have presented an overview of the actual situation, the causes, consequences and solutions of environmental pollution nowadays.
