WHY IS POLLUTION HARMFUL TO OUR ENVIRONMENT?:

WHY IS POLLUTION HARMFUL TO OUR ENVIRONMENT?

PowerPoint Presentation:

pollution of rivers and lakes caused by potential harm and is one of the biggest environmental problems of the 20 th century.

WHAT ARE SOME TYPE OF WATER POLLUTION?:

_There has been an increase thermal pollution due to mainly industrial manufacture.:

_There has been an increase thermal pollution due to mainly industrial manufacture. _Thermal pollution accurse when natural temperature water is interacted water.

And we could end up eating the fish or seafood. :

And we could end up eating the fish or seafood. Thermal pollution is harmful because it causes abnormal effect in our environment , for example a fish could eat some kind of the toxic pollution

If we use water as a coolant by power plants and then returned to the environment at a much higher temperature there a sudden change for animal to adapt to. :

TOXIC WASTE:

The toxic waste pollution has a huge impact on our health and can harm many plants and animals that live in the ocean. Toxic waste is poisonous to our ocean and to us humans too. Toxic waste ends up in the ocean by leaking from landfills , mines , farms etc. Transporting waste to another country runs the frightening risk of spillages. The receiving country often lacks the expertise and technology to deal with the toxic waste in the safest way. Local people are at risk. TOXIC WASTE

OIL POLLUTION:

Oil pollution is a disastrous problem to the ocean. small amounts of oil can form deadly oil slicks. 60 million gallons of oil are spilled into the ocean yearly. Tanker spills are an increasing environmental problem because its almost impossible to completely remove it. Attempts to chemically treat or sink the oil may further disrupt marine and beach ecosystems. OIL POLLUTION

HOW DOES POLLUTION START?:

HOW DOES POLLUTION START?

PowerPoint Presentation:

First of all pollution greatly increased during the industrial revolution in the 19 th century. The smoke in factories caused rivers and lake to become dirty and pollution . In 1952 the great smog in London greatly increase pollution because they burned more coal than usual. This fog lasted for three days killed 4000 people.

WHAT IS AIR POLLUTION?:

Air pollution is when the air is filled with toxins and it can affect our health in negative ways. The air can be contaminated because of acid rain and burning of fossil fuels. also some gases such as carbon dioxide , nitrogen oxide , sulfur oxide create smog and acid rain which is very harmful to the air. Air pollution is the introduction of harmful chemicals that can harm our world. It is one of the biggest concern on our planet , air pollution is most common near places with factories , farm and power plants. WHAT IS AIR POLLUTION?

WHAT CAN WE DO TO SAVE ENVIIROMENT?:

WHAT CAN WE DO TO SAVE ENVIIROMENT?

PowerPoint Presentation:

We should help to decrease and eliminate waste by not using materials that are toxic. Conserve energy by using the amount of energy by using the necessary in you household car pooling and another way to reduce air pollution by using fossil fuels. Plant trees to reduce the amount carbon dioxide in the atmosphere. Use methods to produce another source of electrical energy. recycle reusable items such as aluminum , plastic bottles , glass bottles , cans , paper , boxes and metal etc.
