Development issues in the three biomes

Question 1

STATS.
Total land area protected (%).
Higher plants (number of species)/threatened (%).
Mammals (number of species)/threatened (%).
// Brazil (TRF), Tanzania (savanna grassland), Bangladesh (tropical monsoon forest)//.

Answer 1

Land - 18, 40, 0.5%.
Plants - 56,000 , 10,000,  5,000 
Plants threatened - 0.7,  2.4,  0.2%.
Mammals - 580, 375, 130.
Mammals threatened - 13, 9, 17.

Question 2

What can be noted regarding protection for the 3 different biomes?

Answer 2

Although Brazil has the greatest species diversity (56,000), a smaller proportion of its land (18%) is protected than in Tanzania, (nearly 40% is designated National Parkland).
Bangladesh - high population density, smallest land protection, lowest species diversity. highest % of animals under threat.

Question 3

Why is species diversity important? 4

Answer 3

1. Plants photosynthesise - produces the oxygen that we breathe.
2. Trees act as a carbon sink - absorbing fossil fuel emissions.
3. Some species keep the human race alive by purifying water, fixing nitrogen and recycling nutrients/waste.
4. Insects pollinate crops.

Question 4

Which biome is under the greatest threat (due to economic pressure and population growth)?

Answer 4

Tropical monsoon biome - 7%.
Unknown whether future sustainable development will allow these ecosystems to coexist with economic development and the predicted outcomes of climate change.
