• Remedial Measures:

1. Dispose the waste at proper place.

2. Proper sewerage system.

3. Industries should be outside the population.

4. Use mostly public transport instead of private vehicles.

5. Water should be treated before disposal.

6. Use of chemicals in agriculture as low as possible.

Deforestation • Deforestation is the permanent destruction of forests in order

to make the land available for other uses.

• Factors:

1. To make more land available for housing and urbanization

2. Timber to create commercial items

3. To create ingredients that are highly prized consumer items

• Effects:

1. climate change

2. Loss of species

3. Water cycle

4. Soil erosion

5. Life quality

Deforestation

• Remedial Measures:

1. Reduce population growth.

2. Public awareness should be created against the hazards of deforestation.

3. Increase the area of forest permanently reserved for timber production.

4. Promote sustainable management.

5. Grow more plants.

Natural Resource Depletion

• Resource depletion is the consumption of a resource faster than it can be replenished.

• Natural resources are commonly divided

1. Renewable resources

2. Non-renewable resources

• Factors:

1. Mining

2. Irrigation

3. Overpopulation

4. Pollution

5. Overconsumption

Natural Resource Depletion

• Effects:

1. Global warming.

2. Soil erosion.

3. decrease in biodiversity.

4. changing the water cycle.

5. increasing risks of landslides.

6. As forests get destroyed, so does the habitat for millions of animals.

Natural Resource Depletion

• Remedial Measure:

1. Energy saving homes

2. Replant our cities

3. Eco friendly energy

4. Garbage management

5. Stop using resources you don’t need

6. Be part of the conservation effort
