Protection & Regeneration
Some habitats v.rare = org'ism adapted to habitat under threat
People protect, regen these habitats, can incr. biodiversty (coral reefs, mangroves, heathlands) Coral Reefs - decr. CO2 emissions, global warming to decrease pH levels, temp. for most biodiverse marine habitats; Mangroves - vital for young fish dev, easily destroyed changes in water lvls/salinity (salt-content); Lowland heaths - 20% in UK, disappearing, protect
unique feat. from dev'ers, restoration (remove trees, reverse drainage, allow ponies, cows to graze)
