MAINTENANCE & CHANGES IN THE ECOSYSTEM Project CRITICAL By Sandy Tamayo, Teacher, FDA

Pollution Introducing to the environment substances that are harmful or poisonous effect. The three major type of pollutions are Land pollution Air pollution Water pollution

Land Pollution The major sources of land pollution are Solid waste Pesticides Fertilizers Deforestation Hunting and overfishing

What are the effects of Land Pollution Causes the disruption of habitat, the distuption food chain and the loss of biodiversity. Land pollution causes the contamination of underground water supply

Land pollution

Air Pollution The major sources of air pollution are Littering Burning of fossil fuel Wildfire Factories and industries CFC Chloro-floro-carbon found in air conditioner, refrigerator, Hair spray

How industries and factories contribute to air pollution

How the burning of garbage and wild fire contribute to air pollution

What causes Water pollution Oil spills Pesticides Fertilizers Organic waste Inorganic chemicals Disease causing microorganism Changes in water temp Radio active waste

How solid waste contributes to water pollution

What are the effects of Air pollution Causes the breakdown of the ozone layer that protects us against Ultra Violet light that causes skin cancer. Increases the temp of the earth Causes the green house effect Global warming Global warming causes the melt of the ice caps Raising of sea level Flood

Group activity Students will be divided into water, land and air groups. Students will brainstorm ideas and solutions to the pollution group. Students will share their findings with other group and then share out with the whole class.

How pesticide contributes to water pollution

Manufacturing in China

What can we do as individuals to reduce the Pollution Problems Use the information on the link below and then complete Worksheet 5 from the Public Policy Analyst http://flippedtips.com/plegal/tips/solutions.html

What can we do as individuals to reduce the Pollution Problems Use another type of energy instead of fossil fuel. Car pool or Public transportation, Hybrid cars Tougher Laws and fines, against illegal dumping and factories emission Use of Natural predators instead of pesticides Reduce Reuse Recycle
