2. Biodiversity and
Ecosystem Services

Mr. Allah Dad Khan

4. Clean air:
From old-growth forests to ocean
phytoplankton, the oxygen we breathe is
generated by photosynthesizing members of
ecosystems around the world. Plants also
absorb a variety of pollutants from the air,
and sequester the excess carbon dioxide
emissions that fuel climate change.

5. Clean water:
Forests help soil absorb more water, which
can reduce flooding, limit erosion, filter out
contaminants and refill aquifers. Wetlands
also excel at "phytoremediation," or cleaning
hazardous chemicals from water and soil.
Different species bring different skills, so the
more the merrier

6. Healthy soil:
Soil naturally bustles with lots of arthropods
and microorganisms, which are easy to
overlook but provide a wide range of
benefits. They provide food for slightly larger
creatures, help nutrients cycle through soil,
boost nutrient availability to roots and
enhance plant health, among other things

7. Raw materials:
Biodiverse ecosystems supply us with a
diversity of raw materials, including wood,
biofuels and plant oils that come from both
wild and cultivated species. Materials from
different plants offer different properties,
such as harder or softer wood, or oils with
varying smoke points
