Natural resources supplied by nature like air, water, soil, forests and wildlife are being depleted by human activity which causes issues like global warming and environmental harm. Resources can be renewable like forests which regrow, or non-renewable like fossil fuels which cannot be replaced once used up. Deforestation occurs for many reasons like obtaining land, materials, fuel and construction wood, but it leads to problems through soil erosion, flooding, desertification and climate changes by reducing rainfall. Protecting natural resources and reducing deforestation can help address these environmental impacts.

1. How do we affect the ecosystem
For levels 8

2. Natural Resources
• supplied by nature
• renewable and non- renwable sources
• being depleted by humans which causes
Global warming and harm to everyone.

3. Renewable Non- Renewable
• fossil fuels
• cannot be replaced
when they are used
• Air
• water
• soil
• forests
• wildlife
• should not be overused
• replaced by natural
cycles

4. Deforestations: Why are forests cleared?
• to meet increasing demands for land
• for materials (wood)
• needed for urban development
• growing grassland and animal grazing
• firewood is a source of fuel
• for growing crops
• wood is used as a construction material and
is turned into pulp for making paper

5. Effects of Deforestation
• Soil Erosion
• Flooding
• Desertification
• Climate Changes

6. Soil Erosion
• this is when the top soil (fertile layer) gets
eroded
• leads to flooding
• top soil is exposed to hard rains because the
tree leaves are not there to cover it

7. Flooding
• caused by soil erosion
• eroded soil will be deposited to the rivers,
therefore blocking the flow of water, hence
water level will increase causing flood.

8. Desertification
• it is also caused by over grazing
• since there is no more trees covering the soil,
the sunlight will hit the soil directly.
Therefore, the water in the soil will vaporize
causing the soil to harden and be barren

9. Climate Changes
• When trees are cleared, there will be fewer
clouds, less transpiration and less rainfall
therefore the area becomes dry and warm
hence, rainfall decreases.
