|
2. Sanctuaries |

a place where someone or something is protected or given shelter |
The government has constructed sanctuaries to protect endangered species of animals sduch as the big five. |
|
3. Terrestrial |

Biology immensely losses to the construction of new dams.
Currents efforts to address impacts of dams are insufficient.
New standards that factor this loss of species needs to be effected.
Summary of Article: construction of dams for hydro electric power has led to loss of species thereby leading to a huge loss to biology. This loss was unforeseen and therefore necessary changes need to be done to address this devastating trend. They include better assessment strategies and viability test on the constructions.
