Wildlife Overview
Wildlife traditionally refers to non-domesticated
vertebrates, but has come to broadly refer to all
wild plants, animals and other organisms.
Wildlife can be found in all ecosystems.
Deserts, forests, rain forests, plains, grasslands, and other areas including the most developed urban sites, all have distinct forms of wildlife.

Last concern is depleted uranium (DU) projectiles. Depleted uranium is very dense and is used in projectiles designed to pierce armour, reinforced bunkers and other similar targets. Depleted uranium projectiles create fragments and dust, which release uranium oxide into the air. Estimates of the amount of depleted uranium used by allied forces in the first Gulf War range from 290 ton
It would involve creating large dam-like structure extending from the coast straight to the ocean, with a perpendicular barrier at the far end, forming a large 'T' shape.
The plant is to open the existing dam to allow the circulation and exchange of water between the Lake Sihwa and the sea.
The tidal plant will improve the lake by circulating 60 billion tonnes of seawater annually
