4. TYPES OF PROBLEMS Pollution Littering Greenhouse Effect & Global Warming Deforestation

5. Pollution Pollution harms the Earth’s environment and its people in many ways. Land pollution is pollution of the Earth’s natural land surface by industrial, commercial, domestic and agricultural activities. Some of the main contributions to land pollution are deforestation, construction debris, industrial factories etc. Air pollution is the accumulation of harmful substances into the atmosphere that danger human life and other living matter on the earth. The number one way to prevent air pollution is to walk or bike more and drive less. This will prevent fossil fuels from further polluting the air.

7. Littering It is one of the most current bad customs of today’s society. Every year there are numerous vehicle accidents caused by litter. People in these accidents are injured and sometimes even killed in their attempts to avoid litter in the roadways. Young children fall on litter in playgrounds, get cut and need medical attention. Many small animals crawl into bottles or jars and get stuck and slowly starve to death.

8. Greenhouse effect & Global warming

10. This destruction is also bringing about changes in the climate, air pollution, flooding, drought and famine. If we continue to burn and cut down the rainforests, the earth will never be the same again. As you know, the rainforests in South America are home to half of the world's species and to millions of people. Moreover, the rainforests clean the air by absorbing carbon dioxide and giving out oxygen. The trees are being cut down for paper or to make room for cattle farms' As a result, birds and animals lose their homes and die.

11. We kill the lungs of our planet…

13. Water pollution Water pollution is the contamination of water bodies (e.g. lakes, rivers, oceans and groundwater). Water pollution occurs when pollutants are discharged directly or indirectly into water bodies. Without adequate treatment to remove harmful compounds Water pollution affects plants and organisms living in these bodies of water; and, in almost all cases the effect is damaging not only to individual species and populations, but also to the natural biological communities.

14. Do you like swimming in the sea or drinking a cool glass of water on a hot day? These simple pleasures may soon become a thing of the past. Factories are polluting our rivers and lakes with dangerous chemicals. Oil tankers are releasing thick, black oil into our oceans. Tons and tons of industrial and domestic waste аге poured into our seas. Consequently, sea life is threatened with extinction.

15. Reasons Industrial waste Marine dumping Oil pollution Global warming Radioactive waste Atmospheric deposition

16. Effects Machinery in the industries are cooled with water from lakes and rivers. This water reaches the river in a heated state. This water decreases the ability of the aquatic system to hold oxygen and raises the growth of warm water species. In rivers, oceans and seas, water pollution effects flora and fauna in them. Further, the birds and animals that consume this contaminated food supply can perish. Blood diseases, nervous system disorders and heart diseases are some of the effects of water pollution. Many toxins in polluted water lead to cancer. Rarely, the body's chromosomal makeup can be altered. Some of the less potent effects are skin lesions, vomiting and diarrhea.

17. Solutions: The solution begins at home. We can save the water from our baths and use it for the garden, instead of wasting hundreds of liters of clean water on our lawns and plants. This would help to save many liters of water everyday, especially in summer. Governments can help by passing laws to stop factories from wasting and polluting water. If factories recycled water and stopped pouring chemicals into our lakes and rivers, there would be a lot more clean water around. Governments could also stop water companies from wasting millions of litres of water because of leaking pipes. Many cities have successfully saved water by repairing pipes.
